      tgafb: fix an out-of-range shift in mono imageblit · b738b990
      由 Maciej W. Rozycki 提交于 
      The pixel mask calculation in tgafb_mono_imageblit() uses a variable
left-shift on a 32-bit data type by up to 32.  Shifting by the width of a data
type or more produces an unpredictable result according to the C standard.

Rather than widening the data type this fix makes sure the count is between 0
and 31.  The reason is not to penalise 32-bit platforms with operation on a
"long long" type for a marginal case that is meant not to happen (blitting an
image of a zero width).

The reason it has escaped for so long is the Alpha, being purely 64-bit, :-)
does not mask the shift out to 32 bits.  This is a valid implementation --
producing the correct result certainly falls within "unpredictable behaviour".
 It does trigger on MIPS though and it is the recent merge of the TC support
which only enabled the driver for use on anything other than the Alpha.  For
MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as
it should be and the frame buffer is not updated.

      PCI: Change all drivers to use pci_device->revision · 44c10138
      由 Auke Kok 提交于 
      Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      由 Tim Schmielau 提交于 
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

      [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon · c465e05a
      由 Antonino A. Daplas 提交于 
      According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant.  The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit.  And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.

Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank.  For drivers that do, they can fill up this field with their own
version.

The end result is a smaller code size.  And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
