Make the coredump routine exec-format/emulation specific. Split
out traditional NetBSD coredump routines into core_netbsd.c and
netbsd32_core.c (for COMPAT_NETBSD32).

add RCSIDs, and in some cases, slightly cleanup #include order

uvm_coredump32() moved into compat/netbsd32.

replace vm_map{,_entry}_t with struct vm_map{,_entry} *.

remove trailing whitespace.

In sys_obreak(), the return value of atop() was being used to change
the process dsize for both positive and negative changes. Since atop()
casts its result to a paddr_t (which is unsigned), negative changes in
process data size resulted in unrealistic dsizes being set. Use
"dsize -= atop(-diff)" for a negative diffs. Fixes the "Impossible
process sizes" mentioned on current-users.

Unsigned cast catch and much debugging help from Martin Laubach.

eliminate the KERN_* error codes in favor of the traditional E* codes.
the mapping is:

KERN_SUCCESS 0
KERN_INVALID_ADDRESS EFAULT
KERN_PROTECTION_FAILURE EACCES
KERN_NO_SPACE ENOMEM
KERN_INVAL

Add an align argument to uvm_map() and some callers of that
routine. Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got

How we ever got along without this for so long is beyond me.

fix uvm_coredump32() just like uvm_coredump().

in uvm_coredump(), avoid dumping parts of the stack multiple times
while skipping parts of the stack that hasn't been used.
pointed out by SAITOH Masanobu <masanobu@iij.ad.jp>.

fix a cast for sparc64.

- Avoid an integer overflow when checking if we have exceeded our
rlimit in sbrk. Slightly modified from a patch from Artur Grabowski.
- Rearrange code slightly, partially from Artur Grabowski.

Merge parts of chs-ubc2 into the trunk:

Merge parts of chs-ubc2 into the trunk:
Add a new type voff_t (defined as a synonym for off_t) to describe offsets
into uvm objects, and update the appropriate interfaces to use it, the
most visible effect being the ability to mmap() file offsets beyond
the range of a vaddr_t.

Originally by Chuck Silvers; blame me for problems caused by merging this
into non-UBC.

I should have made uvm_page_physload() take paddr_t's instead of vaddr_t's.
Also, add uvm_coredump32().

CL* clearout

remove now >1 year old pre-release message.

remove unused share map code from UVM:
- update calls to uvm_unmap_remove/uvm_unmap (mainonly boolean arg
has been removed)
- replace UVM_ET_ISMAP checks with UVM_ET_ISSUBMAP checks

Merge paddr_t changes into the main branch.

Don't cast the null residual pointer passed to vn_rdwr().
