The BCM47XX SoC code missed a cpu-feature-overrides.h header file, this
patch adds it. This code supports a long line of SoCs with different
features so for some features we still have to rely on the runtime
detection.
This was crated by checking the features of a BCM4712, BCM4704,
BCM5354, BCM4716 and BCM4706 SoC and then tested on these SoCs. There
are some SoCs missing but I hope they do not have any more or less

CPUs implementing MIPS32 R2 may include a 64-bit FPU, just as MIPS64 CPUs
do. In order to preserve backwards compatibility a 64-bit FPU will act
like a 32-bit FPU (by accessing doubles from the least significant 32
bits of an even-odd pair of FP registers) when the Status.FR bit is
zero, again just like a mips64 CPU. The standard O32 ABI is defined
expecting a 32-bit FPU, however recent toolchains support use of a
64-bit FPU from an O32 MIPS32 executable. When an ELF executable is
built to use a 64-bit FPU a new flag (EF_MIPS_FP64) is set in the ELF
header.
With this patch the kernel will check the EF_MIPS_FP64 flag when
executing an O32 binary, and set Status.FR accordingly. The addition
of O32 64-bit FP support lessens the opportunity for optimisation in
the FPU emulator, so a CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option is
introduced to allow this support to be disabled for those that don't
require it.
Inspired by an earlier patch by Leonid Yegoshin, but implemented more
cleanly & correctly.

ARM: shmobile: kzm9g: Fix coherent DMA mask
ARM: shmobile: armadillo: Fix coherent DMA mask
Helge Deller noted a few weeks ago problems with the AIO support on
parisc. This change is the result of numerous iterations on how best to
deal with this problem.
The solution adopted here is to provide full cache coherency in a
uniform manner on all parisc systems. This involves calling
flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on
kunmap operations. As a result, the copy_user_page() and
clear_user_page() functions can be removed and the overall code is
simpler.
The change ensures that both userspace and kernel aliases to a mapped
page are invalidated and flushed. This is necessary for the correct
operation of PA8800 and PA8900 based systems which do not support
inequivalent aliases.
With this change, I have observed no cache related issues on c8000 and
rp3440. It is now possible for example to do kernel builds with "-j64"
on four way systems.
On systems using XFS file systems, the patch recently posted by Mikulas
Patocka to "fix crash using XFS on loopback" is needed to avoid a hang
caused by an uninitialized lock passed to flush_dcache_page() in the
page struct.

it is only partially successful. Instead of returning the number
of bytes not copied, it now returns 1. This translates to the
wrong value being returned by iov_iter_copy_from_user_atomic.
xfstests generic/246 and LTP writev01 both fail on btrfs and nfs
because of this.

Most of other architectures have below suggested order.
So lets do the same to fit generic idle loop scheme better.

Merge patches from Andrew Morton:
"Ten fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
epoll: do not take the nested ep->mtx on EPOLL_CTL_DEL
sh: add EXPORT_SYMBOL(min_low_pfn) and EXPORT_SYMBOL(max_low_pfn) to sh_ksyms_32.c
drivers/dma/ioat/dma.c: check DMA mapping error in ioat_dma_self_test()
mm/memory-failure.c: transfer page count from head page to tail page after split thp
MAINTAINERS: set up proper record for Xilinx Zynq
mm: remove bogus warning in copy_huge_pmd()
memcg: fix memcg_size() calculation
mm: fix use-after-free in sys_remap_file_pages
mm: munlock: fix deadlock in __munlock_pagevec()
mm: munlock: fix a bug where THP tail page is encountered
Min_low_pfn and max_low_pfn were used in pfn_valid macro if defined
CONFIG_FLATMEM. When the functions that use the pfn_valid is used in
driver module, max_low_pfn and min_low_pfn is to undefined, and fail to
build.
ERROR: "min_low_pfn" [drivers/block/aoe/aoe.ko] undefined!
ERROR: "max_low_pfn" [drivers/block/aoe/aoe.ko] undefined!

Pull s390 fixes from Martin Schwidefsky:
"Two small bug fixes and a follow-up to the CONFIG_NR_CPUS change.
A kernel compiled with CONFIG_NR_CPUS=256 will waste quite a bit of
memory for the per-cpu arrays. Under z/VM the maximum number of CPUs
is 64, the code now limits the possible cpu mask to 64 if running
under z/VM"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/pci: obtain function handle in hotplug notifier
s390/3270: fix allocation of tty3270_screen structure
s390/smp: improve setup of possible cpu mask
Three reasons for doing this: 1. arch.walk_mmu points to arch.mmu anyway
in case nested EPT wasn't in use. 2. this aligns VMX with SVM. But 3. is
most important: nested_cpu_has_ept(vmcs12) queries the VMCS page, and if
one guest VCPU manipulates the page of another VCPU in L2, we may be
fooled to skip over the nested_ept_uninit_mmu_context, leaving mmu in
nested state. That can crash the host later on if nested_ept_get_cr3 is
invoked while L1 already left vmxon and nested.current_vmcs12 became
NULL therefore.

Update arch.apic_base before triggering recalculate_apic_map. Otherwise
the recalculation will work against the previous state of the APIC and
will fail to build the correct map when an APIC is hardware-enabled
again.
This fixes a regression of 1e08ec4a13.
