- We don't need to test the console right before we vfprintf() the panicstr
message. The printing of the panic message is a fine console test by
itself and doesn't make useful messages scroll off the screen or tick
developers off in quite the same.

* Switch to proc0's stack and backing store before calling ia64_init
so that we don't rely on the loader's stack at all.
* Change kernel entry point name from locorestart to __start.
'struct tty' was out of sync in user and kernel due to dev_t/udev_t
mixups. This takes advantage of the fact that dev_t changes type in
userland, so it isn't too pretty.
overflow if uap->nsops (which is already unsigned) is over INT_MAX;
consequently, the bounds check below becomes valid. Previously, if a
value over INT_MAX was passed in uap->nsops, the bounds check wouldn't
catch it, and the value would be used to compute copyin()'s third
argument.

and linux_sendsig functions guarded their debugging output with
ldebug(sigreturn). This has been mistaken for a cut-n-paste bug,
and was replaced by ldebug(rt_sendsig) and ldebug(sendsig) resp.
Since the sendsig functions are not syscalls, this brokei any
build that defines DEBUG.
The fix maps both functions to the unused syscall 0 so that they
can be enabled/disabled independently from sigreturn, but not
independently from each other.
it to the MI area. KSE touched cpu_wait() which had the same change
replicated five ways for each platform. Now it can just do it once.
The only MD parts seemed to be dealing with fpu state cleanup and things
like vm86 cleanup on x86. The rest was identical.
XXX: ia64 and powerpc did not have cpu_throw(), so I've put a functional
stub in place.

an array "fs_contigdirs[]" to avoid too many directories getting
created in each cylinder group. The memory required for this and
two other arrays (fs_csp[] and fs_maxcluster[]) is allocated with
a single malloc() call, and divided up afterwards. However, the
'space' pointer is not advanced correctly, so fs_contigdirs and
fs_maxcluster end up pointing to the same address.
Add the missing code to advance the 'space' pointer, and remove
an unnecessary update of the pointer that follows.
This is likely to fix the "ffs_clusteralloc: map mismatch" panics
that have been reported recently.

should fix a number of memory corruption problems and also should stop the
mtimes of executables changing all the time.

ELFMAG is the magic; SELFMAG is the size of the magic. Use with
strncmp() or memcmp().

me (addition of vn_rdwr_inchunks). The problem Yahoo is solving is that
if you have large process images core dumping, or you have a large number of
forked processes all core dumping at the same time, the original coredump code
would leave the vnode locked throughout. This can cause the directory vnode
to get locked up, which can cause the parent directory vnode to get locked
up, and so on all the way to the root node, locking the entire machine up
for extremely long periods of time.
This patch solves the problem in two ways. First it uses an advisory
non-blocking lock to abort multiple processes trying to core to the same
file. Second (my contribution) it chunks up the writes and uses bwillwrite()
to avoid holding the vnode locked while blocking in the buffer cache.
