(xen) bug-fixes for 3.0-rc2: stable/bug.fixes (and potentially stable/vga.support)

Hey Linus,

Please git pull the two (or one) following branches:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/bug.fixes stable/vga.support

The #stable/bug.fixes is based on (v3.0-rc1) tag and has two bug-fixes:
1). Dan found an past the array comparison. That bug has been in the code
since 2.6.27 - so lurking for quite a while.
2). Based on testing we found a bug in the IRQ code where we would "forget" to
ACK edge interrupts (such as PS/2 keyboard) and the user would be left without the usage of a keyboard. This only happened during guest creation on specific hardware - but the bug is generic that it could happened on any hardware.

The #stable/vga.support is based off 2.6.39 and here I am going to defer to your judgment whether you would be OK pulling it in or if I should defer to v3.1 with it.

The patch adds VGA text support for the Linux kernel to boot under the Xen hypervisor. In the past we have been using the frame-buffer (so KMS) or serial console so it never occurred to me to actually look at the VGA text output (and hence the reason why I did not include it in the initial git pull for 3.0-rc1) - but it is still important for users with servers where they don't want to use KMS or Xorg - and without this patch they won't be able to see anything. Furthermore folks have been popping up on the mailing list testing 3.0-rc1 and this is the first thing they notice not working right :-(

The patch is contained within the Xen code base so the potential regression impact on other platforms is nill.

xen: allow enable use of VGA console on dom0

Hello,

If still possible, stable/vga.support branch is important for Linux 3.0,
since many people have already gotten bitten by the (accidently) missing vga text console support..

That vga text console patch only affects Xen, so it's safe to pull, even for 3.0-rc4 ..

Thanks,
