b1b09da029 When using clang, do not use the sparc64 code as it doesn't provide the 
full set of symbols and clang in -m32 defaults to sparcv8, not
sparcv8plus.

98e9d5f901 Put back the rump-disabling of mcount for librump. Otherwise the world 
breaks because the mcount assembly code is written to call __mcount via
the PLT.

c2acaf5fa5 __mcount_lock is moved to MI from MD. 
because it is needed for all MULTIPROCESSOR arch, but it is exists only in i386 and amd64.

ed17c7296b Use gcc 4.4 and later operation for nand, i.e. 
*ptr = ~(tmp & value) instead of *ptr = ~tmp & value

There was also another bug in sync_fetch_and_nand_8 which I've also fixed.

3940a87a45 Improve the code in __sync_bool_compare_and_swap_{1,2,4}. 
- bccs is smaller and faster than bcc(.w) in this case.
- it can be used movql in this case (assembler optimise it though).

1ce375c3b8 Always use sync if mips3 or later or not using O32 ABI. (A little redundant 
since not using O32 means you are using mips3 or later.)

272b1fe359 Don't treat NUL (EOF) as SPACE. All the code that uses _PROP_ISSPACE() checks 
explicitly for _PROP_EOF() anyway, and this can be abused to cause run beyond

5a2ca44c60 Switch to the suggested constant-time result conversion. 
Not hard to find CPU/compiler combinations with branches for `!res'.

While here, make everything unsigned for good measure.

6d40f9ff57 add a new "fo_mmap" fileops method to allow use of arbitrary uvm_objects for 
mappings of file objects.  move vnode-specific details of mmap()ing a vnode
from uvm_mmap() to the new vnode-specific vn_mmap().  add new uvm_mmap_dev()
and uvm_mmap_anon() convenience functions for mapping character devices
and anonymous memory, and replace all other calls to uvm_mmap() with those.
use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).
