is a forwards jump instead of a backwards jump that a P4 will mispredect (and
probably immediatly get a cache-line miss due to the way the code gets
aligned).
extra argument to ensure that 'off_t' parameters are even numbered
parameters for stack alignment reasons on 32 bit systems) to use a normal
'syscall' wrapper for __foo instead of using __syscall(SYS_foo, ... ).
This saves all the faffing needed to get a 32bit return value on sparc.
Auto-generate the extra syscall wrappers.
Move swapon.c into the correct list (swapon() uses swapctl()).
This probably means there are very few users of syscall() and __syscall() left.
also synchronizes with puffs_mount() and does not return (exit) in the
parent process until the file system has been mounted. This makes
it possible to reliably run e.g. mount_foo jippi /kai ; cd /kai/ee
- Play scrooge again and chop more cycles off acquire/release.
- Spin while the lock holder is running on another CPU (adaptive mutexes).
- Do non-atomic release.
Threadreg:
- Add the necessary hooks to use a thread register.
- Add the code for i386, using %gs.
- Leave i386 code disabled until xen and COMPAT_NETBSD32 have the changes.
- Override __libc_thr_init() instead of using our own constructor.
- Add pthread__getenv() and use instead of getenv(). This is used before
we are up and running and unfortunatley getenv() takes locks.
Other changes:
- Cache the spinlock vectors in pthread__st. Internal spinlock operations
now take 1 function call instead of 3 (i386).
- Use pthread__self() internally, not pthread_self().
- Use __attribute__ ((visibility("hidden"))) in some places.
- Kill PTHREAD_MAIN_DEBUG.
for misc support routines and put it there.
- Add a libc constructor. Use this to initialize threading and the
stack protector stuff. libpthread cannot be initialized safely using
its own constructor because libc and libpthread are deeply intertwined.

This adds reachover Makefiles to build the libatf library and enables it in
the parent Makefile.
Things to review in this change:
* Add proper version numbers in the shlib_version files.
* Is libatf properly listed in lib/Makefile? It theoretically needs
libstdc++, but the resulting binary library is not linked against it.
This function allows the caller finer control of how the writes happen
and doesn't force stdio as interface. Optimise clear_gap a bit to not
fill the gap byte-wise. Bump minor version of libkvm.
we try to set both in one ioctl, to the same value, which fails if not
both record and play direction support that many channels. (Having
more play than record channels is common these days.)
This does likely address part of the problem described in PR pkg/35444
by Mihai Chelaru, and it helped Matthew R. Green about half a year
ago -- see the thread in tech-misc in April.
