4ad8530004 sun4v: Rename TLB_ defines to SUN4U_TLB_ so entries created using TSB_DATA() are properly setup for sun4u and sun4v. Relocate the cputyp variable from autoconf.c to locore.s and make it const in param.h so optimized code can be generated. Parts from OpenBSD. Optimization suggested by nakayama@.

7c166415e7 Remove the #include <sys/user.h> from all of libkvm. 
sys/user.h is a stub that just #includes sys/pcb.h.
There are no 'struct pcb' anywhere in here, so I'm extremely doubtful
any of the builds will fail.
OTOH it might be relying on a header that pcb.h includes.
In any case i386 and amd64 build.

ce92aca1d5 Bounce the minimum allocation alignement for sparc64 and amd64 as well, 
to sync with their default gcc configuration.
We could relax this again later, after a filing a defect report with the
ISO C comitee and getting an answer contradicting the gcc teams
interpretation (and then fix the gcc target configurations instead).

177c2413c9 minor clarification: rumpuser_thread_create() is used to create the host 
thread context for kernel threads, never for application threads.

03dbd38792 Err on the safe side for small memory allocations and provide 4byte 
alignment by default.  Override this to 8byte alignment for alpha and arm
eabi.

Someone (tm) can review this change once the standards and compiler(s)
have sorted themselves out.

2e17c78b61 pthread__mutex_lock_slow: fix the handling of a potential race with the 
non-interlocked CAS in the fast unlock path -- it is unsafe to test for
the waiters-bit while the owner thread is running, we have to spin for
the owner or its state change to be sure about the presence of the bit.
Split off the logic into the pthread__mutex_setwaiters() routine.

This is a partial fix to the named lockup problem (also see PR/44756).
It seems there is another race which can be reproduced on faster CPUs.

2934fa70dc Limit the amount of kernel memory a posix_spawn syscall can use (for handling 
the file action list) by limiting the maximum number of file actions to
twice the current file descriptor limit.
Fix a few bugs in the support functions and document the new limit.

shuffle register argument so the kernel won't need to access the stack to

de79b4937c PR/44756: Sad Clouds: Prevent leakage of errno = ESRCH from _lwp_park. This 
has two parts:
	- in pthread_cond_timedwait() if the thread we are trying to unpark
	  exited, retry the the _lwp_park call without it.
	- pthread_mutex() was affecting errno since it is calling _lwp_park()
	  from pthread_mutex_lock_slow(). preserve the original errno.
Note that the example problem still causes an occassional deadlock on machines
with many CPUs and it is the same deadlock we observe with named.

969b8a91e4 Since N32/N64 pass the first 8 arguments in registers, we can load all 
the arguments into those registers before invoking the syscall having
the kernel syscall handler from having to do that.
