{Free,Open}BSD say that we have to do some work to make fxp
stable.

dfe7b794ce Always make sure that kte_entry is aligned appropriately so register_t can 
be stored there.  (not really a problem right now since time_t is now 64bit
bit and it just works but it's better to be explicit).

0e730cfa32 Use a alternative dedicated signal stack for the sigsegv errors; the userland 
stack like that of ld.elf_so can be too short to allow for such deep
stacktraces.

acf0c89366 redo vfs_lookup.c rev.1.126. 
when crossing a mount point, don't keep the parent vnode locked.
ie. don't lock a vnode while holding another vnode which belongs to a
different filesystem.  otherwise we propagate slowness (or deadness) of a
filesystem to another via vnode lock chain.

fc8de2b005 Enhance debugging capabilities of NetBSD/usermode by allowing `trap.c' to 
write a system image of the memory it traps. Its extremely dirty but at least
you can look at the data and code thats giving the trouble. Its memory or
state is NOT saved in the coredump of the NetBSD/usermode program.

c41a9ea5e1 It seems mvsata_bio_ready() is actually needed, and it seems 
to work better if we always poll for completion for the
duration of this function.

883c2687f6 We occasionally will try to set up the multicast filter in a context that 
kmem(9) is unusable (such as transmit timeout). Thus, put the filter table
on the stack instead, all 528 bytes of it.

74623c9c5f Initialize MVGBE_MTU to 0, as suggested by the Orion databook. 
If the platform firmware did not initialize this to 0 for us,
we were unable to transmit frames.

1641c82fac Update pcc snapshot to 1.1.0.DEVEL 20110901 
Continual development has happened since the previous 0.9.9
snapshot of 20100603 and the full commit log is too long to
include here, but can be seen at

 http://pcc.ludd.ltu.se/fisheye/changelog/~date=2011-09-01T06%3A00%3A00/pcc

Many bugs were reported and fixed, along with reworks of the compiler
internals in several areas, notable milestones were

 * more builtins, libpcc is no longer required on NetBSD
 * improved gcc compatibility (eg gnu-inline semantics)
 * NetBSD/VAX kernel compiles and boots
 * using cpp as backend for lint now fully working
 * PIC support seems complete
 * NetBSD/i386 kernel can be compiled and booted
 * better float/double/complex support
 * amd64 support on OSX
 * reworked Makefiles
 * pcc 1.0.0 was release on April 1 2011
 * several xasm improvements
 * FreeBSD/amd64 system can be compiled with very few changes
 * DragonFly fixes from downstream
 * rewritten #pragma support
 * TLS support added
 * many regression tests
 * rewrite of internal attribute handling

9a1b6b7c8b Minor nit: avoid kpreempt_disable() if cold (as we return early and do 
not reenable it; actually makes no difference but looks more balanced
this way)

207bff18bc Forward some UVM from matt-nb5-mips64. Add UVM_KMF_COLORMATCH flag. 
When uvm_map gets passed UVM_FLAG_COLORMATCH, the align argument contains
the color of the starting address to be allocated (0..colormask).
When uvm_km_alloc is passed UVM_KMF_COLORMATCH (which can only be used with
UVM_KMF_VAONLY), the align argument contain the color of the starting address
to be allocated.
Change uvm_pagermapin to use this.  When mapping user pages in the kernel,
if colormatch is used with the color of the starting user page then the kernel
mapping will be congruent with the existing user mappings.
