nfs must not use MINORBITS - that fails with 32-bit dev_t

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.

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.

We need to validate that the address and length of a MAP_FIXED request are
suitable for hugetlb pages.

Patch from James Curbo <phoenix@sandwich.net>

The amd74xx IDE driver in 2.5.59 has support for the nforce IDE controller,
but not explicitly for the nforce2 IDE controller (which has a different PCI
ID, which is in the kernel already).  I'm not sure if the nforce and nforce2
controllers are identical, but I made a small patch that made the amd74xx
driver recognize the nforce2 IDE, and it boots for me, seems to work fine, as
my drives were tuned to their highest transfer rate automatically (udma5).

I don't know if this patch is proper or correct, but it Works for Me [tm].
Patch is attached.

This was found by the Standford Checker.
The LogicalDeviceNumber bad range test was changed from > to >=
I also replaced a couple of panic() calls with error messages,
since panic-ing seemed a little extreme.

journal_try_start() is a function which nonblockingly attempts to open a JBD
transaction handle.  It was added a long time ago when there were concerns
that ext3_writepage() could block kswapd for too long.

It was never clearly necessary.

So the patch throws it all away and just calls the blocking journal_start()
from ext3_writepage().

uninline get_jiffies_64() for 32-bit architectures

Quote ',$ before passing them to the shell - ' must be escaped for
echo, $$ will be converted to $ by make.

This allows to use e.g. perl commands in the build with support

When the user selects CONFIG_MODVERSIONS but doesn't build anything
modular, the post-processing step does nothing (right, as there is
nothing to be done), but it also gave an error, which it shouldn't.

Some versions of sed seem to think \w, as in word, doesn't include
digits, which breaks the build with CONFIG_MODVERSIONS. So we
just use the more compatible [<space><tab>]*.
