Define preprocessor symbols (__HAVE_OPENFIRMWARE_VARIANT_AAPL and
__HAVE_OPENFIRMWARE_VARIANT_SUNW) that lets generic OpenFirmware
code deal with differences / quirks among implementation variants.

branches: 1.28.16;
Overhaul the API used to fetch and store individual memory cells in
userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms. The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Welcome to NetBSD 8.99.37.

branches: 1.27.14;
provide __HAVE_COMPAT_NETBSD32 and fix multiple include protection consistently.

branches: 1.26.6; 1.26.10; 1.26.14;
Allow TOPDOWN-VM only for binaries compiled with appropriate code model.
No change yet, as __HAVE_TOPDOWN is not yet defined.

merge ktrace-lwp.

Now that sparc has syscall intern, no need to define it here too.

Re-factor syscall, and make it use syscall_{plain,fancy}.

branches: 1.22.6;
use <sparc/foo.h> where appropriate. now these files become very
very difficult to get out of sync. add bootinfo.h and promlib.h
(using the same method) so that sparc64 headers can build sparc
stand (not yet finished.)

branches: 1.21.2;
Revert revision 1.20.

Provide _LP64 definition if we are generating LP64 binaries.

Use "#define<tab>".

defopt "options SUN4*", put #define for each of SUN4, SUN4C, SUN4M and SUN4U
into opt_arch_sparc.h and include this wherever they are used.

branches: 1.17.2; 1.17.8;
Delint my previous change.

* Move definitions of exact-width integer types from <machine/types.h>
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.

branches: 1.15.2;
Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS,
and place the definition in <machine/types.h>. This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.

replace 'long long' with int64_t to compile stand alone program with
compiler other than GCC.

Remove __BROKEN_CONFIG_UNIT_USAGE. (sync with sparc)

add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very
wrong things with device configuration data "cf_unit" information.

#define __HAVE_DEVICE_REGISTER on ports that have it, and check for
that, rather than a list of architecture defines, in config_attach

Apparently sys/sysctl.h includes vm/vm_map.h which makes use of vaddr_t,

merge sparc64 types.h; these files are now identical.

branches: 1.8.8; 1.8.14;
retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.

Make register32_t unsigned so we don't have sign extension problems.

Some more 64-bit cleanup. Now everything compiles.

Fix typo in previous fix.

64-bit-ify this. Depend on _lp64.

Merge paddr_t changes into the main branch.

branches: 1.2.2;
Merge in recent changes:
GC the unused `physadr' type, which was not able to hold a complete physical
address on 2 architectures anyhow. Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.
