8b96cb8a97 Back out the per-cpu arena changes. With this, ld.so magically stops 
loading libc/libpthread twice -- which does not make sense, because it
has its own private malloc().

b565a56cfb - On 64-bit platforms 1/2 the default tsd values were garbage. Fix it. 
- The lwpctl block is now needed on uniprocessors, for pthread_curcpu_np().

21913eabe5 Rototill. 
Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?).  Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it.  This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.

There's still a little to do on this front, but this was the major
fs interface blast.

aadcb17f11 * allocate pcc as a slice from the stack instead of allocating it 
separately

This is in preparation for the removal of you-should-guess-what as
an argument to routines here and there and everywhere.

f6cecc05cf Sync phk malloc.c with the latest one from FreeBSD. This gives us the 
same api as jemalloc by:

    - adding posix_memalign()
    - moving calloc in the same file
    - renaming malloc_options -> _malloc_options

d8e8042c1c Add a note about the difficulty of actually looking at the return value 
of __syscall() caused by ABIs (eg sparc) that don't pass the low bits of
a 64 bit result in the same register as a 32 bit result.

3ba44b945b Reorder the code for i386 and amd64 syscall stubs so that the 'jc' on error 
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).

b0b7248d92 Change all the syscall C 'glue' functions (most of which just add in an 
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.

3537e99eb1 Introduce puffs_daemon(), which works like daemon(3) except that it 
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

66ac2ffaf2 Mutexes: 
- 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.
