Impact: fix failed EFI bootup in certain circumstances
Ying Huang found init_memory_mapping() has problem with small ranges
less than 2M when he tried to direct map the EFI runtime code out of
max_low_pfn_mapped.
It turns out we never considered that case and didn't check the range...

The following patch enables SMC911x support to work on the OMAP LDP
board. Although the SMC911x driver will eventually be obsoleted, the
smsc911x patches are rather invasive for the -rc kernels.
Rather than risk destablising smsc911x, this simpler patch is preferred
to allow the network interface to work.

* 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
fix warning in io_mapping_map_wc()
x86: i915 needs pgprot_writecombine() and is_io_mapping_possible()
|

On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with
ljmp, and then use the "syscall" instruction to make a 64-bit system
call. A 64-bit process make a 32-bit system call with int $0x80.
In both these cases under CONFIG_SECCOMP=y, secure_computing() will use
the wrong system call number table. The fix is simple: test TS_COMPAT
instead of TIF_IA32. Here is an example exploit:
/* test case for seccomp circumvention on x86-64
There are two failure modes: compile with -m64 or compile with -m32.
The -m64 case is the worst one, because it does "chmod 777 ." (could
be any chmod call). The -m32 case demonstrates it was able to do
stat(), which can glean information but not harm anything directly.
A buggy kernel will let the test do something, print, and exit 1; a
fixed kernel will make it exit with SIGKILL before it does anything.

There was a theoretical possibility to a race between arming a page in
post_kmmio_handler() and disarming the page in
release_kmmio_fault_page():
cpu0 cpu1
------------------------------------------------------------------
mmiotrace shutdown
enter release_kmmio_fault_page
fault on the page
disarm the page
disarm the page
handle the MMIO access
re-arm the page
put the page on release list
remove_kmmio_fault_pages()
fault on the page
page not known to mmiotrace
fall back to do_page_fault()
*KABOOM*
(This scenario also shows the double disarm case which is allowed.)
Fixed by acquiring kmmio_lock in post_kmmio_handler() and checking
if the page is being released from mmiotrace.

Blindly setting _PAGE_PRESENT in disarm_kmmio_fault_page() overlooks the
possibility, that the page was not present when it was armed.
Make arm_kmmio_fault_page() store the previous page presence in struct
kmmio_fault_page and use it on disarm.

Print a full warning once, if arming or disarming a page fails.
Also, if initial arming fails, do not handle the page further. This

Virtex FPGA designs have two serial port logic cores to choose from; the
simple uartlite, and the full featured uart16550. Both cores are in
common use so the defconfig should support both of them. Currently
only console on uartlite is supported in the defconfig. This patch adds
console support for the 16550 core.
The Virtex reference designs do not work without this patch.

Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:
- Use clk_enable()/clk_disable() ... the "always enable USB clocks"
code this originally relied on has since been removed.
- Initialize the USB device only after the relevant I2C GPIOs are
available, so the host side can properly enable VBUS.
- Tweak init sequencing to cope with mainline's relatively late init
of the I2C system bus for power switches, transceivers, and so on.
Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also
verified on OMAP3.
(Unrelated: correct the MODULE_PARM_DESC spelling of musb_debug.)

arch_initcall() runs after the machine init function which means that
any configuration of GPIO pins must currently be done later on, for
example in callbacks from drivers. Move the initialisation earlier in
order to allow machines to configure GPIOs directly in their init
functions rather than having to have a callback invoked later on.
Some other ARM platforms use this method. Other solutions for this
include providing a special interface for setting up GPIOs en masse,
adding callbacks to do the GPIO configuration from devices and doing
the GPIO configuration implicitly.

The PCI 2.x cells used on some 44x SoCs only let us configure the decode
for the low 32-bit of the incoming PLB addresses. The top 4 bits (this
is a 36-bit bus) are hard wired to different values depending on the
specific SoC in use. Our code used to work "by accident" until I added
support for the ISA memory holes and while at it added more validity
checking of the addresses.
This patch should bring it back to working condition. It still relies
on the device-tree being correct but that's somewhat a pre-requisite
for anything to work anyway.

With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first. The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.
As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.
As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest. Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.

it here too. The fix is the same as that applied to memcpy() with the
addition of fixes for the exception handling code required for
__copy_tofrom_user().

This fixes a regression introduced by commit
25d6e2d7c58ddc4a3b614fc5381591c0cfe66556 ("powerpc: Update 64bit memcpy()
using CPU_FTR_UNALIGNED_LD_STD").
This commit allowed CPUs that have the CPU_FTR_UNALIGNED_LD_STD CPU
feature bit present to do the memcpy() with unaligned load doubles. But,
along with this came a bug where our final load double would read bytes
beyond a page boundary and into the next (unmapped) page. This was caught
by enabling CONFIG_DEBUG_PAGEALLOC,
The fix was to read only the number of bytes that we need to store rather
than reading a full 8-byte doubleword and storing only a portion of that.
In order to minimise the amount of existing code touched we use the
original do_tail for the src_unaligned case.
Below is an example of the regression, as reported by Sachin Sant:
