66e1a311f5 Fix brk(3). The stack was unbalanced when we jumped to cerror. Oops! 
This causes nasty things like SEGV or a cpu spin when we return.

b4f9f84b96 1. Move thread list flags into new separate member, and atomically 
put DEAD thread on GC list, this closes a race between pthread_join
   and thr_cleanup.
2. Introduce a mutex to protect tcb initialization, tls allocation and
   deallocation code in rtld seems no lock protection or it is broken,
   under stress testing, memory is corrupted.

d4ddb4f67f Revert 1.18: It broke Athlon64 builds, which 
probably means it also requires a .so version

5dbd7addb0 1. Now that it's a thread's state is changed from within the kernel, where 
no userland locks are heald, the dead thread lock can no longer protect
   access to it. Therefore, instead of using an if (!dead)...else clause
   after walking the active threads list test the thread pointer before
   deciding not to walk the dead threads list. If the thread pointer is null
   it means it was not found in the active threads list and the dead threads
   list should be checked.

2. Do not free the stack of a thread that is not marked dead. This is the
   2nd and final part of eliminating the race to free a thread's stack.

2bdd560907 Belatedly catch up with the dev_t/cdev changes from a few months back. 
Extract the struct cdev pointer and the tty device from inside rather than
incorrectly casting the 'struct cdev *' pointer to a 'dev_t' int.  Not
that this was particularly important since it was only used for reading
vmcore files.

dbc8f2b5ce More updates for math(3): 
- Make some minor rearrangements in the introduction.
- Mention the problem with argument reduction on i386.
- Add recently-implemented functions to the table.
- Un-document the error bounds that only apply to the old 4BSD math
  library, and fill in the correct values where I know them.  No
  attempt has been made to document bounds lower than 1 ulp, although
  smaller bounds are usually achievable in round-to-nearest mode.
