martin ececdb7913 When passing char (or unsigned char) arguments as int, assign them to a
temporary char (resp. unsigned char) before comparing, to force truncation
to the proper domain. This makes the coresponding regression tests succeed.

ad 9324487752 Include sys/simplelock.h in prop_object_impl.h. 2008-01-05 01:15:02 +00:00
mjf 83535b7f11 Nuke prop_dictionary_capacity, there was no implementation for it.
No objections on tech-kern.

mrg 97e461c633 - provide 32 bit versions of the sparc v9 atomic ops.
- use them on sparc64 32 bit kernels.

fixes issues on 32 bit sparc64 kernels that were using sparc v8 ops.
tested by rjs@.

tsutsui 3e9910f3b8 Disable a sanity check output buffer != NULL in _STANDALONE case.
Some kernels are loaded at address 0x0 by bootloaders and
output buffer address could be zero in such case.

Fixes "read text" errors on loading install floppy of NetBSD/news68k 4.0,
reported by KIYOHARA Takashi on port-news68k.

ad e16a661bf3 - Make __cpu_simple_lock and similar real functions and patch at runtime.
- Remove old x86 atomic ops.
- Drop text alignment back to 16 on i386 (really, this time).
- Minor cleanup.

the includes.

joerg 22ac6fc0fb Add x86emu for in-kernel use. This is a 386 real mode emulator that can
be used to run ROM code inside the kernel without having to setup vm86
and without having a x86 CPU at hand.

This code was originally written by SciTech and released under MIT/X11
license for XFree86. It has been refactored be less than half of the
original size, the compiled code being around a third of the former
size. The interface was changed to be a real library, e.g. no global
variables are used.
