Since the secondary CPUs will not be operating in symetric mode
while they are held in the pen, we need to ensure that the write
to pen_release is visible to them, by flushing the cache.

Since ARMv6 CPUs will not flush the TLB on context switches, it is
possible that we may end up with some global TLB entries remaining
present, eventually upsetting userspace.  Explicitly flush the
entire TLB on secondary CPUs as they startup, after we have switched
to the init_mm page tables.

If we haven't configured the qla24xx driver, then the Makefile shouldn't
do it for us.

This also means that we can avoid the unnecessary selection of FC_ATTRS.

On 8xx, in the case where a pagefault happens for a process who's not
the owner of the vma in question (ptrace for instance), the flush
operation is performed via the physical address.

Unfortunately, that results in a strange, unexplainable "icbi"
instruction fault, most likely due to a CPU bug (see oops below).

Avoid that by flushing the page via its kernel virtual address.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

The fb_info struct, as defined in include/linux/fb.h, contains an element
that is supposed to hold the current color map:
  struct fb_cmap cmap;            /* Current cmap */

This cmap is currently never updated when either fb_set_cmap() or
fb_set_user_cmap() are called.  As a result, info->cmap contains the
default cmap that was set by a device driver/fbcon and a userspace
application using the FBIOGETCMAP ioctl will not always get the *currently*
used color map.

The patch fixes this by making sure the cmap is copied to info->cmap after
it is set correctly.  It moves most of the code that is responsible for
setting the cmap to fb_set_cmap() and out of fb_set_user_cmap() to avoid
code-duplication.

Currently even when the cursor is disabled (`setterm -cursor off`), it is
still repainted as a black rectangle the size of a single char.  This can
be seen, for example, by chvt'ing to a free tty, disabling the cursor and
doing `dd if=3D/dev/urandom of=3D/dev/fb0`.

The patch changes this behaviour by avoiding painting anything when the
cursor is disabled.

Color maps have up to 256 entries.  4096/256 allows for 16 characters per
line.  The format for a cmap entry is "%02x%c%4x%4x%4x\n" %02x entry %c
transp %4x red %4x blue %4x green

You can read the color_map with cat fb0/color_map.

m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early
on boot because the VM is not fully up yet.  Change it to use the on-board
DPRAM instead.

The current code relies on the "bootmem_page" allocated by
m8xx_cpm_reset(), which must be killed.

This is done in v2.4 but has never been forward ported to v2.6.

I am changing the name of this module now so that hopefully the name will
be changed before the release of 2.6.13 ...  It wouldn't make sense to
release 2.6.13 with the name lgdt3302 in it, which will only be renamed to

I noticed that some past changes to the gerneric Video4Linux tuner module
for analog tuners broke my "Multimedia eXtension Board" driver.

The tuner driver was made aware of Video4Linux2 tuning ioctls, but my
driver was not ported and still uses the Video4Linux1 ioctls.  This does
not work anymore as intendend, the tuning is currently broken.

The attached patch fixes non-working tuning in MXB driver introduced by
some recent generic tuner changes by replacing Video4Linux1 tuner ioctls
with proper Video4Linux2 tuner ioctls.

It is a small modification to the table that defines the way that the
LG-Z201 tuner is controlled for the DVICO Fusion DVB-T1 tuner card.

I believe that a mistake was made when the dvb tuner code was reorganised
(to use a generic table for the tuner information instead of inline code)
and as a result, the DVICO card doesn't tune properly.

The modification I have made to the table makes it behave like it did with
the old inline tuner code that worked.  The patch is on top of the 2.6.12
kernel.
