a26164117a Reorganize symbol table embedding. The existing option SYMTAB_SPACE is 
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

95739e63cd Remove __HAVE_PROCESS_XFPREGS and add the extra parameter for the size 
of the fp save area to all the process_read_fpregs() and
  process_write_fpregs() functions.
None of the functions have been modified to use the new parameters.
The size is set for all the writes, but some of the arch-specific reads
  just pass NULL.
The amd64 (and i386) need variable sized fp register save areas in order
  to support AVX and other enhanced register areas.
These functions are rarely called - so the extra argument won't matter.

8a7df726af Fix IO lockups in NetBSD/usermode. 
1) Don't block IO signals since the return path is not garanteed to enable the
signal again.
2) Since signals can get dropped, do a 2nd pass over the routines.

8ce4433821 Do not call setroot() from MD code and from MI code, which has 
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

88bfa5cb05 Move from pool(9) to kmem_zalloc(9) for L2 page tables. A pool with PAGE_SIZE 
elements is accepted but seems to panic now and then claiming it can't find
the header info.

XXX should this be PR'd?

54e9432c0a Prevent recursive IO signals. This prevents crashes when pieces of text are
