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.

Lock iir(4) and mark it MPSAFE. - Add a per-device mutex to the softc and use it for bus_dma tags, CAM SIMs, callouts, and interrupt handler. - Switch from timeout(9) to callout(9). - Add a separate global mutex to protect the global event buffer ring. - Return completed index from iir_intr_locked() and remove the global gdt_wait_* variables. - Remove global list of gdt softcs and replace its use with devclass_get_device(). - Use si_drv1 to store softc pointer in the SDEV_PER_HBA case instead of minor numbers. - Do math on osreldate instead of dubious char math on osrelease[] that didn't work on 10.0+. - Use bus_*() instead of bus_space_*(). - Use device_printf() instead of printf() with a unit number.

Re-do r255853. Along with adding back the API/ABI changes from the original, this hides the contents of cam_compat.h from ktrace/kdump/truss, avoiding problems there. There are no user-servicable parts in there, so no need for those tools to be groping around in there.

Update the CAM API for FreeBSD 10:
- Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0; MPSAFE drivers should be managing their own timeout storage. The remaining non-MPSAFE drivers have been modified to also manage their own storage, and should be considered for updating to MPSAFE (or removal) during the FreeBSD 10.x lifecycle.
- Add fields related to soft timeouts and quality of service, to be used in upcoming work.
- Add room for more flags in the CCB header and path_inq structures.
- Begin support for extended 64-bit LUNs.
- Bump the CAM version number to 0x18, but add compat shims. Tested with camcontrol and smartctl.

Prepare for future integration between CAM and newbus. xpt_bus_register now takes a device_t to be the parent of the bus that is being created. Most SIMs have been updated with a reasonable argument, but a few exceptions just pass NULL for now. This argument isn't used yet and the newbus integration likely won't be ready until after 7.0-RELEASE.

Big update to the iir driver: - Don't use a common buffer in the softc to store per-command data. Reserve a buffer in the command itself. - Don't allocate DMA memory for the kernel command structures when all you really need is DMA memory for the scratch buffer embedded in them. Instead allocate a slab for the scratch buffers and divide it up as needed. - Call bus_dmamap_unload() at the completion of commands. - Preserve and clear the CAM CCB status flags at completion. - Reorder some low-level command operations to try to close races. - Limit the simq to 32 commands for now. There are some serious problems with the driver under load that are not well understood, so keeping the simq lower helps avoid this. It has been tested at a higher value, but this is a safe value that doesn't show much performance degredation.
These changes allow the driver to work reliably with >4GB of memory on i386 and amd64, and also work around deadlocks seen under very high load in certain situations. The work-around is far from ideal, but without and documentation it is hard to know what the right fix is.

netchild's mega-patch to isolate compiler dependencies into a central place.
This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.
By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

These are changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. It doesn't affect the operation if gcc.
Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as icc v8 may define __GNUC__ some parts may look strange but are necessary.
Additional changes: - in_cksum.[ch]: * use a generic C version instead of the assembly version in the !gcc case (ASM code breaks with the optimizations icc does) -> no bad checksums with an icc compiled kernel Help from: andre, grehan, das Stolen from: alpha version via ppc version The entire checksum code should IMHO be replaced with the DragonFly version (because it isn't guaranteed future revisions of gcc will include similar optimizations) as in: ---snip--- Revision Changes Path 1.12 +1 -0 src/sys/conf/files.i386 1.4 +142 -558 src/sys/i386/i386/in_cksum.c 1.5 +33 -69 src/sys/i386/include/in_cksum.h 1.5 +2 -0 src/sys/netinet/igmp.c 1.6 +0 -1 src/sys/netinet/in.h 1.6 +2 -0 src/sys/netinet/ip_icmp.c

and finally remove sys/i386/i386 in_cksum.c sys/i386/include in_cksum.h ---snip--- - endian.h: * DTRT in C++ mode - quad.h: * we don't use gcc v1 anymore, remove support for it Suggested by: bde (long ago) - assym.h: * avoid zero-length arrays (remove dependency on a gcc specific feature) This change changes the contents of the object file, but as it's only used to generate some values for a header, and the generator knows how to handle this, there's no impact in the gcc case. Explained by: bde Submitted by: Marius Strobl <marius@alchemy.franken.de> - aicasm.c: * minor change to teach it about the way icc spells "-nostdinc" Not approved by: gibbs (no reply to my mail) - bump __FreeBSD_version (lang/icc needs to know about the changes)
Incarnations of this patch survive gcc compiles since a loooong time, I use it on my desktop. An icc compiled kernel works since Nov. 2003 (exceptions: snd_* if used as modules), it survives a build of the entire ports collection with icc.
Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.

Add the following functions/macros to support byte order conversions and device drivers for bus system with other endinesses than the CPU (using interfaces compatible to NetBSD):
- bwap16() and bswap32(). These have optimized implementations on some architectures; for those that don't, there exist generic implementations. - macros to convert from a certain byte order to host byte order and vice versa, using a naming scheme like le16toh(), htole16(). These are implemented using the bswap functions. - stream bus space access functions, which do not perform a byte order conversion (while the normal access functions would if the bus endianess differs from the CPU endianess).
htons(), htonl(), ntohs() and ntohl() are implemented using the new functions above for kernel usage. None of the above interfaces is currently exported to user land.
Make use of the new functions in a few places where local implementations of the same functionality existed.
