Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Replace several bus_alloc_resource() calls using default arguments with bus_alloc_resource_any()
Since these calls only use default arguments, bus_alloc_resource_any() is the right call.

Converted the isa probe and attach to new-bus so that this driver works without the (defunct) isa compatibility shims. The new-bus-specific parts are very similar to the ones for the pci probe and attach.
This was held up too long waiting for a repo copy to src/sys/dev/cy, so I decided to fix the files in their old place. This gives easier to read and merge diffs anyway.
The "count" line in src/sys/conf/files won't be changed until after the repo copy, so old kernel configs that specify a count need not be (and must not be) changed until then. The count is just ignored in the driver. One unfinished detail is dynamic allocation of arrays with <count> and (<count> * 32) entries, and iteration over the arrays. This is now kludged with a fixed count of 10 (up to 10 cards with up to 32 ports each).

Fixed breakage of the pci case of the cy driver by the new interrupt code. Both the driver and the new code were wrong. Driver interrupt handlers are supposed to take "void *vsc" arg, but some including all COMPAT_ISA drivers and the pci part of the cy driver want an "int unit" arg. They got this using bogus casts of function pointers which should have kept working despite their bogusness. However, the new interrupt code doesn't honor requests to pass an arg of ((void *)0), so things are very broken if the arg is actually a representation of unit 0.
The fix is to use a normal "void *vsc" arg for the pci case and a wrapper for the COMPAT_ISA case (of the cy driver). This cleans up new-busification of the pci case but takes the COMPAT_ISA case a little further from new-bus. The corresponding bug for the COMPAT_ISA case has already been fixed similarly using a wrapper in compat_isa.c and we need another wrapper just to undo that.
Fixed some directly related style bugs (mainly by removing compatibility cruft).
cy.c: Fixed an indirectly related old bug in cyattach_common(). A wrong status was returned in the unlikely event that malloc() failed.

Restored the call to schedsofttty() (now spelled swi_sched(...)) again. Its restoration in rev.1.102 was mistranslated to the equivalent of setsofttty() in rev.1.105. This increased overheads by causing a context switch to the SWI handler after almost every interrupt. The increase was approx. 50% on a Celeron 366 (from 23 usec to 34 usec per interrupt).

Quick fix for bitrot in locking in the SMP case. cd_getreg() and cd_setreg() were still using !(read_eflags() & PSL_I) as the condition for the lock hidden by COM_LOCK() (if any) being held. This worked when spin mutexes and/or critical_enter() used hard interrupt disablement, but it has caused recursion on the non-recursive mutex com_mtx since all relevant interrupt disablement became soft. The recursion is harmless unless there are other bugs, but it breaks an invariant so it is fatal if spinlocks are witnessed.

Change the suser() API to take advantage of td_ucred as well as do a general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

Change the preemption code for software interrupt thread schedules and mutex releases to not require flags for the cases when preemption is not allowed:
The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent switching to a higher priority thread on mutex releease and swi schedule, respectively when that switch is not safe. Now that the critical section API maintains a per-thread nesting count, the kernel can easily check whether or not it should switch without relying on flags from the programmer. This fixes a few bugs in that all current callers of swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from fast interrupt handlers and the swi_sched of softclock needed this flag. Note that to ensure that swi_sched()'s in clock and fast interrupt handlers do not switch, these handlers have to be explicitly wrapped in critical_enter/exit pairs. Presently, just wrapping the handlers is sufficient, but in the future with the fully preemptive kernel, the interrupt must be EOI'd before critical_exit() is called. (critical_exit() can switch due to a deferred preemption in a fully preemptive kernel.)
I've tested the changes to the interrupt code on i386 and alpha. I have not tested ia64, but the interrupt code is almost identical to the alpha code, so I expect it will work fine. PowerPC and ARM do not yet have interrupt code in the tree so they shouldn't be broken. Sparc64 is broken, but that's been ok'd by jake and tmm who will be fixing the interrupt code for sparc64 shortly.

Modify the critical section API as follows: - The MD functions critical_enter/exit are renamed to start with a cpu_ prefix. - MI wrapper functions critical_enter/exit maintain a per-thread nesting count and a per-thread critical section saved state set when entering a critical section while at nesting level 0 and restored when exiting to nesting level 0. This moves the saved state out of spin mutexes so that interlocking spin mutexes works properly. - Most low-level MD code that used critical_enter/exit now use cpu_critical_enter/exit. MI code such as device drivers and spin mutexes use the MI wrappers. Note that since the MI wrappers store the state in the current thread, they do not have any return values or arguments. - mtx_intr_enable() is replaced with a constant CRITICAL_FORK which is assigned to curthread->td_savecrit during fork_exit().

- Overhaul the software interrupt code to use interrupt threads for each type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD.

* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be preempted (i386 only).

Flush the fifos at the correct place in cyopen(). Various things in cyopen() were done in a different order than in sioopen(), partly to (ab)use a side effect of comparam() and partly because I didn't understand what the reset was doing (it flushes the fifos). This turned out to be more than a cosmetic problem. Flushing the fifos quite late is good for discarding input that arrived while the line state was being initialized, and in the cy driver it also seems to reduce a problem with input that arrived long ago during the previous close (the UART loses sync too easily and for too long).

Wait for channel commands to complete after issuing the commands. The optimisation of only waiting before issuing new commands is obviously invalid in general and it caused many errors in NIST-PCTS. I think the errors were mostly for characters sent with the wrong parity, etc., after a half complete tcsetattr().
Use microtime() instead of a magic loop count to limit the wait. The wait is a busy-wait :-( and normally takes about 500 usec.

Flush the tx fifo in cystop(). Now ttyflush() (and thus tcflush(3)) almost works properly. Unfortunately, there is no way to flush the rx fifo without resetting the channel, which also flushes the tx fifo. We avoid resetting even when both fifos need to be flushed, since resetting seems to cause the rx to lose sync if it is done while data is arriving.

Implemented sending of BREAKs. This is quite complicated because the hardware is interrupt-driven to a fault and sending a BREAK requires mode switching. Always running in the BREAK-capable mode as in PR 8318 would double the overhead for sending \0's.

Fixed sloppy clearing of TS_BUSY. Don't clear it until the transmitter is completely empty. There is an interrupt for output completion. It is painful to use, but polling method used in the corresponding fix in sio.c (rev.1.152) can't be used because there is no status bit for transmitter-empty. Now ttywait() works right.

Untangled the Cyclades offsets a little. CY16_RESET and CY_CLEAR_INTR were half of their physical offsets for ISA and 1/4 of their physical offsets for PCI, while all other Cyclades offsets were physical/1 for ISA and physical/2 for PCI. Logically wrong macros were used to scale CY16_RESET and CY_CLEAR_INTR to the correct physical offsets.
Fixed some style bugs (mostly long lines).

Reduce i/o overheads by not preserving the channel access register in interrupt handlers. Instead, load and use it atomically as necessary. This reduces mode switching overhead for "polled" mode interrupt handling from 5 i/o's to 3 (per service type, per port) so that polled mode is only slightly more inefficient than "interrupt" mode.

Don't call ttsetwater() explicitly in open(). It is now called for the TTYDISC l_open() and should be static.

Pass 3 of the great devsw changes most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter)
If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job.. (pass 5 :)
pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

OK, that's it.. That's EVERY SINGLE driver that has an entry in conf.c.. my next trick will be to define cdevsw[] and bdevsw[] as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry that comes in very early.. and asks teh driver to add it's own entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT stuff and some usually wrong but token DEVFS entries to all these devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside? seems we don't actually have a 'ataopen() etc...
If you want to add a new device in conf.c please make sure I know so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD) (and #ifdef DEVFS in parts)

the second set of changes in a move towards getting devices to be totally dynamic.
this is only the devices in i386/isa I'll do more tomorrow. they're completely masked by #ifdef JREMOD at this stage... the eventual aim is that every driver will do a SYSINIT at startup BEFORE the probes, which will effectively link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn) The ioconf lines generated by config will also end up in the device's own scope as well, so ioconf.c will eventually be gutted the SYSINIT call to the driver will include a phase where the driver links it's ioconf line into a chain of such. when this phase is done then the user can modify them with the boot: -c config menu if he wants, just like now.. config will put the config lines out in the .h file (e.g. in aha.h will be the addresses for the aha driver to look.) as I said this is a very small first step.. the aim of THIS set of edits is to not have to edit conf.c at all when adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made, all teh time still having a fully working kernel tree, but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as run-time loaded drivers, except they JUST HAPPEN to already be linked and present at startup.. the SYSINIT calls will be the equivalent of the "init" call made to a newly loaded driver in every respect.
For this edit, each of the files has the following code inserted into it:
obviously, tailored to suit.. ----------------------somewhere at the top: #ifdef JREMOD #include <sys/conf.h> #define CDEV_MAJOR 13 #define BDEV_MAJOR 4 static void sd_devsw_install(); #endif /*JREMOD */ ---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT #ifdef JREMOD sd_devsw_install(); #endif /*JREMOD*/ -----------------------at the bottom: #ifdef JREMOD struct bdevsw sd_bdevsw = { sdopen, sdclose, sdstrategy, sdioctl, /*4*/ sddump, sdsize, 0 };
struct cdevsw sd_cdevsw = { sdopen, sdclose, rawread, rawwrite, /*13*/ sdioctl, nostop, nullreset, nodevtotty,/* sd */ seltrue, nommap, sdstrategy };

sio.c: Fix the tests for being a console by reverting to the ones that were used before the the RB_SERIAL changes. RB_SERIAL only needs to be tested in one place. The initialization of comconsole was wrong before the RB_SERIAL changes for the COMCONSOLE case. This may have been the cause of the unnecessary changes.
Start eliminating #includes of <i386/i386/cons.h>. This header is supposed to be included from <machine> although it should be completely machine-independent and included from <sys>.
Remove a wrong XXX comment. `comconsole' is used to test for being a console and even the tests for deciding the default termios state are necessary (the semi-reentrant i/o routines don't handle ordinary device i/o).

Improve input flow control.
Use input buffer watermarks of TTYHOG-512 (high) and (high)*7/8 (low) instead of TTYHOG/2 (high) and TTYHOG/5 (low) to agree with some drivers. 512 is magic and some things depended on TTYHOG/2 >= TTYHOG-512 to work; now they depend on the 512 magic not changing and TTYHOG-512 being significantly larger than 0. This should be handled in ttsetwater().
Separate the decision about whether to do input flow control from doing it. ttyblock() now just starts input flow control (hardware and/or software) and there is a new function ttyunblock() to stop it. The decisions are the same except for the watermark changes and allowing for input expansion for PARMRK.
When flushing input, try harder at first to send a start character if required, but give up if the first attempt fails.
cy.c, rc.c, sio.c: Simplify: let ttyinput() handle input flow control if it is not being bypassed. Use ttyblock() to start flow control otherwise.
rc.c: Use same input flow control test as elsewhere: test in a more efficient order and start flow control at >= highwater instead of at > highwater.

Move the inline code for waking up writers to a new function ttwwakeup(). The conditions for doing the wakeup will soon become more complicated and I don't want them duplicated in all drivers.
It's probably not worth making ttwwakeup() a macro or an inline function. The cost of the function call is relatively small when there is a process to wake up. There is usually a process to wake up for large writes and the system call overhead dwarfs the function call overhead for small writes.

(a) remove the pointer to each driver's tty structure array from cdevsw (b) add a function callback vector to tty drivers that will return a pointer to a valid tty structure based upon a dev_t (c) make syscons structures the same size whether or not APM is enabled so utilities don't crash if NAPM changes (and make the damn kernel compile!) (d) rewrite /dev/snp ioctl interface so that it is device driver and i386 independant

Avoid duplicating ttselect() so that we don't have to change cyselect() when ttselect() is improved. This requires using an array of tty structs and not using ttymalloc().
Fix an off by 1 error. Some caclulations seem to be off by a factor of NCY. NCY defaults to 16, which gives 256 tty structs occupying 0xd000 bytes. The minor number encoding only allows 16 ttys.
Update the types of timeout functions to 2.0.
