POWER architecture CPUs (Book-S) require natural alignment for
cache-inhibited storage accesses. Since we can't know the caching model
for a page ahead of time, always enforce natural alignment in bcopy.
This fixes a SIGBUS when calling the function with misaligned pointers
on POWER7.

The computed IPOIB_CM_RX_SG is too small. It doesn't account for fallback
to mbuf clusters when jumbo frames are not available and it also doesn't
account for the packet header and trailer mbuf.
This causes a memory overwrite situation when IPOIB_CM is configured.
While at it add a kernel assert to ensure the mapping array is not overwritten.

Currently running `truss -a -e` does not decode any
argument values for freebsd32_* syscalls (open/readlink/etc.)
This change checks whether a syscall starts with freebsd{32,64}_ and if
so strips that prefix when looking up the syscall information. To ensure
that the truss logs include the real syscall name we create a copy of
the syscall information struct with the updated.
The other problem is that when reading string array values, truss
naively iterates over an array of char* and fetches the pointer value.
This will result in arguments not being loaded if the pointer is not
aligned to sizeof(void*), which can happens in the compat32 case. If it
happens to be aligned, we would end up printing every other value.
To fix this problem, this changes adds a pointer_size member to the
procabi struct and uses that to correctly read indirect arguments
as 64/32 bit addresses in the the compat32 case (and also compat64 on
CheriBSD).
The motivating use-case for this change is using truss for 64-bit
programs on a CHERI system, but most of the diff also applies to 32-bit
compat on a 64-bit system, so I'm upstreaming this instead of keeping it
as a local CheriBSD patch.

This fixes a long-standing but very obscure bug in fsck_ffs when
it is run with the -R (rerun after unexpected errors). It only
occurs if fsck_ffs finds duplicate blocks and they are all contained
in inodes that reside in the first block of inodes (typically among
the first 128 inodes).
Rather than use the usual ginode() interface to walk through the
inodes in pass1, there is a special optimized `getnextinode()'
routine for walking through all the inodes. It has its own private
buffer for reading the inode blocks. If pass 1 finds duplicate
blocks it runs pass 1b to find all the inodes that contain these
duplicate blocks. Pass 1b also uses the `getnextinode()' to search
for the inodes with duplicate blocks. Pass 1b stops when all the
duplicate blocks have been found. If all the duplicate blocks are
found in the first block of inodes, then the getnextinode cache
holds this block of bad inodes. The subsequent cleanup of the inodes
in passes 2-5 is done using ginode() which uses the regular fsck_ffs
cache.
When fsck_ffs restarts, pass1() calls setinodebuf() to point at the
first block of inodes. When it calls getnextinode() to get inode
2, getnextino() sees that its private cache already has the first
set of inodes loaded and starts using them. They are of course the
trashed inodes left over from the previous run of pass1b().
The fix is to always invalidate the getnextinode cache when calling
setinodebuf().

documention.
Commit SVN r364219 / Git 8a0edc914f changed random(9) to be a shim around
prng32(9) and inadvertently caused random(9) to begin returning numbers in the
range [0,2^32-1] instead of [0,2^31-1], where the latter has been the documented
range for decades.
The increased output range has been identified as the source of numerous bugs in
code written against the historical output range e.g. ipfw "prob" rules and
stats(3) are known to be affected, and a non-exhaustive audit of the tree
identified other random(9) consumers which are also likely affected.
As random(9) is deprecated and slated for eventual removal in 14.0, consumers
should gradually be audited and migrated to prng(9).

During a recent NFSv4 testing event a test server caused a hang
where "umount -N" failed. The renew thread was sleeping on "nfsv4lck"
and the "umount" was sleeping, waiting for the renew thread to
terminate.
This is the second of two patches that is hoped to fix the renew thread
so that it will terminate when "umount -N" is done on the mount.
This patch adds a 5second timeout on the msleep()s and checks for
the forced dismount flag so that the renew thread will
wake up and see the forced dismount flag. Normally a wakeup()
will occur in less than 5seconds, but if a premature return from
msleep() does occur, it will simply loop around and msleep() again.
The patch also adds the "mp" argument to nfsv4_lock() so that it
will return when the forced dismount flag is set.
While here, replace the nfsmsleep() wrapper that was used for portability
with the actual msleep() call.
