xen pvfb: Dynamic mode support (screen resizing)
The pvfb backend indicates dynamic mode support by creating node
feature_resize with a non-zero value in its xenstore directory.
xen-fbfront sends a resize notification event on mode change. Fully
backwards compatible both ways.
Framebuffer size and initial resolution can be controlled through
kernel parameter xen_fbfront.video. The backend enforces a separate
size limit, which it advertises in node videoram in its xenstore
directory.
xen-kbdfront gets the maximum screen resolution from nodes width and
height in the backend's xenstore directory instead of hardcoding it.
Additional goodie: support for larger framebuffers (512M on a 64-bit
system with 4K pages).
Changing the number of bits per pixels dynamically is not supported,
yet.

xen: Enable console tty by default in domU if it's not a dummy
Without console= arguments on the kernel command line, the first
console to register becomes enabled and the preferred console (the one
behind /dev/console). This is normally tty (assuming
CONFIG_VT_CONSOLE is enabled, which it commonly is).
This is okay as long tty is a useful console. But unless we have the
PV framebuffer, and it is enabled for this domain, tty0 in domU is
merely a dummy. In that case, we want the preferred console to be the
Xen console hvc0, and we want it without having to fiddle with the
kernel command line. Commit
b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7
did that for us.
Since we now have the PV framebuffer, we want to enable and prefer tty
again, but only when PVFB is enabled. But even then we still want to
enable the Xen console as well.
Problem: when tty registers, we can't yet know whether the PVFB is
enabled. By the time we can know (xenstore is up), the console setup
game is over.
Solution: enable console tty by default, but keep hvc as the preferred
console. Change the preferred console to tty when PVFB probes
successfully, unless we've been given console kernel parameters.

ipsec: Use the correct ip_local_out function
Because the IPsec output function xfrm_output_resume does its
own dst_output call it should always call __ip_local_output
instead of ip_local_output as the latter may invoke dst_output
directly. Otherwise the return values from nf_hook and dst_output
may clash as they both use the value 1 but for different purposes.
When that clash occurs this can cause a packet to be used after
it has been freed which usually leads to a crash. Because the
offending value is only returned from dst_output with qdiscs
such as HTB, this bug is normally not visible.

down.

a device that has been removed from the system. The node_id and
generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET

And if you guess the correct generation to use, you can send requests to

x86: strengthen 64-bit p?d_bad()
The x86_64 pgd_bad(), pud_bad(), pmd_bad() inlines have differed from
their x86_32 counterparts in a couple of ways: they've been unnecessarily
weak (e.g. letting 0 or 1 count as good), and were typed as unsigned long.
Strengthen them and return int.
The PAE pmd_bad was too weak before, allowing any junk in the upper half;
but got strengthened by the patch correcting its ~PAGE_MASK to ~PTE_MASK.
The PAE pud_bad already said ~PTE_MASK; and since it folds into pgd_bad,
and we don't set the protection bits at that level, it'll do as is.

Fix the warning:
include2/asm/pgtable.h: In function `pte_modify':
include2/asm/pgtable.h:290: warning: left shift count >= width of type
On 32-bit PAE the virtual and physical addresses are both 32-bits,
so it ends up evaluating 1<<32. Do the shift as a 64-bit shift then
cast to the appropriate size. This should all be done at compile time,
and so have no effect on generated code.

x86: define PTE_MASK in a universally useful way
Define PTE_MASK so that it contains a meaningful value for all x86
pagetable configurations. Previously it was defined as a "long" which
means that it was too short to cover a 32-bit PAE pte entry.
It is now defined as a pteval_t, which is an integer type long enough
to contain a full pte (or pmd, pud, pgd).
This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the
NX bit in mprotect due to the incorrect type/value of PTE_MASK reported
by Hugh Dickins:
"Yes, thanks Jeremy: I've checked that each stage builds and runs X on
my boxes here, x86_32 and x86_32+PAE and x86_64. (So even 1/8 is
enough to fix the PAT pte_modify issue, though 2/8 then fixes
compiler warnings.)"

HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.
This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.
If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.
Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.
