Since daemonize now blocks all signals, this simplification is trivially
correct.

Not that it makes any difference on x86, but there may be
architectures that actually need it.

Add a name argument to daemonize() (va_arg) to avoid all the
kernel threads having to duplicate the name setting over and
over again.

Make daemonize() disable all signals by default, and add a
"allow_signal()" function to let daemons say they explicitly
want to support a signal.

Make flush_signal() take the signal lock, so that callers do
not need to.

Patch from Roland McGrath.

This patch replaces the assumption that > PAGE_OFFSET == kernel address
with testing for user_mode(regs) and inserting switch codes instead.

This patch allows the oprofilefs files to take entry in any base
instead of just base 10

This patch updates the horrible enum for the logical CPU type with a
string instead.

The below patch implements a P4 driver for OProfile, mostly written
by Graydon Hoare.

tasks (even if we don't otherwise need to wake anything up), since
otherwise later signals would see that signals are already pending and
wouldn't cause wakeups.

wake_up_forked_process() unconditionally enables interrupts.  It is called
from sched_init().  Enabling interrupts that early makes Anton's ppc64
machine lock up.

This fixes several trivial bounds/limits errors that were pointed out by
the Stanford Checker.

This fixes a potential divide-by-zero found by the Stanford Checker.

The few platforms that cannot use the generic
get_signal_to_deliver implementation cannot do
so because they do special things for ptraced
children.  This can be easily avoided and thus
all of the signal handling code duplication can
be eliminated.

This is the first part, which adds a platform hook
right before the parent of the ptraced child is woken.
Data can be passed in via a cookie argument.

The next part will be dealing with platforms
that need to muck with breakpoints in the child
in this same code block.

My previous round of EISA hacking left the 3c59x driver unable to
compile on non-PCI systems (that is, EISA only...).

This small patch fixes it.

Fix compilation of 3c509.c

Patch from: Eric Lammerts <eric@lammerts.org>

Every time you do a loop mount, a kernel thread is started (those
processes are called "loop0", "loop1", etc.). The problem is that when
it starts, it's counted as one of your processes. Then, it's
changed to be a root-owned process without correcting that count.

Patch below fixes the problem. It moves the bookkeeping of changing
current->user to a new function switch_uid() (which is now also used
by exec_usermodehelper() in kmod.c). The patch is tested.

mempools have the wrong semantics for use by buffer_heads.  The problem
scenario:

- Process A calls mempool_alloc(), asking for a buffer_head.

- While process A sleeps, process B frees up a ton of memory.

That's it.  There is no longer any memory pressure, so nobody frees any
buffer_heads, so process A does not get woken up.  I managed to trigger this
in some testing recently.

One approach would be to use a schedule_timeout(2) in mempool_alloc().

Anyway, the importance of buffer_head allocation was lessened when swapout
stopped using them, so let's just drop the mempool out of it for now.

A very long time ago ext3_fill_super() was beng called under the VFS's
lock_super(), and it had to drop that lock for deadlock avoidance reasons.

But the VFS was later changed to not take lock_super() across ->fill_super(),
so we're upping a non-downed semaphore.

Just take it out.

Redo the (strange) layout of some of Roger's comments.

No need to check root->rnode in the loop. In the loop it remains nonzero.
