The following patch adds support for the XScale performance monitoring unit
to OProfile.  It uses not only the performance monitoring counters, but
also the clock cycle counter (CCNT) allowing for upto 5 usable counters.

The code has been developed and tested on an IOP331 (hardware courtesy of
Intel) therefore i haven't been able to test it on XScale PMU1 systems. 
Testing on said systems would be appreciated, and if done, please uncomment
the #define DEBUG line at the top of op_model_xscale.c

OProfile userspace support has already been committed and should be
available via CVS.

Only x86 implements pmdisk_arch_suspend().  So mark pmdisk as ia32-only, to
avoid breaking allyesconfig.

This patch fixes a bug where /proc displays 1 less logical volume than is
actually configured.  This causes problems for some installers.

Here is a patch to make sysfs optional.  Note that with CONFIG_SYSFS=n you
must specify the boot device's major:minor on the kernel boot command line
with

	root=03:01

For embedded systems, it will save a significant amount of memory during
runtime.  And, it saves 4k from the built kernel image for me.

Based on initial patch from Andreas Gruenbacher there is now better support
for building external modules with kbuild.

The preferred syntax is now:
make -C $KERNELSRC M=$PWD

but the old syntax:
make -C $KERNELSRC SUBDIRS=$PWD modules
will remain supported.

The major differences compared to before are that:
1) No attempt is made to neither check nor update any files in $KERNELSRC
2) Module versions are now supported

During stage 2 of kernel compilation where the modules are built, a new file
Module.symvers is created.  This file contains the version for all symbols
exported by the kernel and any module compiled within the kernel tree.

When the external module is build the Module.symvers file is being read and
symbol versions are used from that file.

The purpose of avoiding any updates in the kernel src is that usually in a
distribution the kernel src will be read-only, and there is no need to try to
update it.  And when building an external module the focus is on the module,
not the kernel.

I expect the distributions will start using something like this:

kernel src - with no generated files. Not even .config:
/usr/src/linux-<version>

Output from build:
/lib/modules/linux-<version>/build

where build is a real directory with relevant output files and the
appropriate .config.

I have some Documentation in the pipe-line, but wants to see how this
approach is received before completing it.

This patch is made on top of the previously posted patch to divide
make clean in three steps.

And you may need to edit the following line in the patch to make it apply:
 %docs: scripts_basic FORCE
to
 %docs: scripts FORCE

From: Sam Ravnborg <sam@ravnborg.org>

Previously 'make clean' deleted all automatically generated files.  The
following patch revert this behaviour, and now 'make clean' leaves enough
behind to allow external modules to be built.

The cleaning is now done in three steps:

make clean     - delete everything not needed for building external modules
make mrproper  - delete all generated files, including .config
make distclean - delete all temporary files such as *.orig, *~, *.rej etc.

This fixes reports about nvidia and vmware build issues.

From: Sam Ravnborg <sam@ravnborg.org>

From: Herbert Xu <herbert@gondor.apana.org.au>

It seems that the %docs targets only needs scripts_basic.  The following
patch does just that.  This removes its dependency on the existence of a
.config file.

fb_copy_cmap() takes an argument about wether to do memcpy, copy_from_user or
copy_to_user.  0 is memcpy, 2 is copy_to_user.  In the ioctl you want
copy_to_user for copying the colormap to userspace.

From: Arjan van de Ven <arjanv@redhat.com>

Patch below fixes a thinko in the frame buffer drivers; the code does

cursor.image.data = kmalloc(size, GFP_KERNEL);
....
cursor.mask = kmalloc(size, GFP_KERNEL);
....
                if (copy_from_user(&cursor.image.data, sprite->image.data, size) ||
                    copy_from_user(cursor.mask, sprite->mask, size)) {
....

where it's clear that the & in the first copy_from_user is utterly bogus
since the destination is the content of the newly allocated buffer, and not
the pointer to it as the code does.

oopses have been reported in do_acct_process(), with premption enabled, when
threaded applications are exitting.

It appears that we're racing with another thread which is nulling out
current->tty.  I think this race is still there after we moved current->tty
into current->signal->tty, so let's take the needed lock.

clear_bit(n, addr) clears the nth bit.
test_and_clear_bit(n, addr) clears the nth bit.
cpu_clear(n, cpumask) clears the nth bit (vs. cpus_clear()).
bitmap_clear(bitmap, n) clears out all the bits up to n.

Moreover, there's a CLEAR_BITMAP() in linux/types.h which bitmap_clear() is
a wrapper for.

Rename bitmap_clear to bitmap_zero, which is harder to confuse (yes, it bit
me), and make everyone use it.

From: Rusty Russell <rusty@rustcorp.com.au>

Sam Ravnborg found these.

1) have_vmlinux is a global, and should not be reset every time.

2) We pretend every module needs cleanup_module so it gets versioned,
   but that isn't defined for CONFIG_MODULE_UNLOAD=n.

3) The visible effect of this is that modpost will start complaning about
   undefined symbols - previously this happened only when the module was
   isntalled.

From: <john.l.byrne@hp.com>

In do_fork(), if an error occurs after the mm_struct for the child has been
allocated, it is never freed.  The exit_mm() meant to free it increments
the mm_count and this count is never decremented.  (For a running process
that is exitting, schedule() takes care this; however, the child process
being cleaned up is not running.) In the CLONE_VM case, the parent's
mm_struct will get an extra mm_count and so it will never be freed.

This patch should fix both the CLONE_VM and the not CLONE_VM case; the test
of p->active_mm prevents a panic in the case that a kernel-thread is being
cloned.

particular, and studied the other uses and definitions of

This patch makes serial line registration in the ibmasm service processor
driver depend on CONFIG_SERIAL_8250.  Previously the driver wouldn't
compile when serial driver support wasn't enabled.

From: Evan Felix <evan.felix@pnl.gov>

Here is a patch that fixes a major issue in the raid5/6 code.  It seems
that the code:

logical_sector = bi->bi_sector & ~(STRIPE_SECTORS-1);
(sector_t)     = (sector_t)    & (constant)

that the right side of the & does not get extended correctly when the
constant is promoted to the sector_t type.  I have CONFIG_LBD turned on so
sector_t should be 64bits wide.  This fails to properly mask the value of
4294967296 (2TB/512) to 4294967296.  in my case it was coming out 0.  this
cause the loop following this code to read from 0 to 4294967296 blocks so
it could write one character.

As you might imagine this makes a format of a 3.5TB filesystem take a very
long time.
