If the DIU framebuffer driver is not enabled, then there's no point in
compiling any platform DIU code, because it will never be used. Most of
the platform code was protected in the appropriate #ifdef, but not all.
This caused a break in some randconfig builds.
This is only a problem on the 512x platforms. The P1022DS and MPC8610HPCD
platforms are already correct.
This patch reverts commit 12e36309f8 ("powerpc:
Option FB_FSL_DIU is not really optional for mpc512x") and restores the
ability to configure DIU support.

The usual rules for open()/openat()/open_by_handle_at() are
1) native 32bit - don't force O_LARGEFILE in flags
2) native 64bit - force O_LARGEFILE in flags
3) compat on 64bit host - as for native 32bit
4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for
native 64bit
There are only two exceptions - s390 compat has open() forcing
O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same
thing. The same binaries on native host (s390/31 and arm resp.) will
*not* force O_LARGEFILE, so IMO both are emulation bugs.

When a cpu enters S3 state, the FPU state is lost.
After resuming for S3, if we try to lazy restore the FPU for a process running
on the same CPU, this will result in a corrupted FPU context.
Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU,
so nobody will try to lazy restore a state which doesn't exist in the hardware.
Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off,
by doing thousands of suspend/resume cycles with 4 processes doing FPU
operations running. Without the patch, a process is killed after a
few hundreds cycles by a SIGFPE.

The SP804 driver statically initialises the cpumask of the clock event
device to be cpu_all_mask, which is derived from the compile-time
constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback
on the irq_chip, because the common timer code fails to identify the
device as cpu-local and ends up treating it as a broadcast device
instead.
This patch fixes the problem by using cpu_possible_mask at runtime,
which will correctly represent the possible CPUs when SMP_ON_UP is being
used.

There appear to have been some 486 clones, including the "enhanced"
version of Am486, which have CPUID but not CR4. These 486 clones had
only the FPU flag, if any, unlike the Intel 486s with CPUID, which
also had VME and therefore needed CR4.
Therefore, look at the basic CPUID flags and require at least one bit
other than bit 0 before we modify CR4.

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities. This is useful for the C
decompressor implementations used for unpacking compressed kernels.
This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.
The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.
For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

The new EEH code introduced a small regression, if the EEH PEs
are missin (which happens currently in qemu for example), it
will deref a NULL pointer in the MSI code.

A few more fixes for final 3.7. Two dealing with pinmux setup on OMAP, and
one dealing with TV output on DaVinci. And one small MAINTAINER update.

The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not
allowed because of the const-ness.
Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.
Without this patch, building ixp4xx_defconfig results in:

It doesn't make much sense to map QMgr dynamically - we almost always need it
and the static mapping will be needed for little-endian data-coherent operation
(to make QMgr region value-coherent).
