Add a nearly-complete ARMv7 short descriptor implementation, omitting
only a few legacy and CPU-centric aspects which shouldn't be necessary
for IOMMU API use anyway.

The 'umidi' object will be free'd on the error path by snd_usbmidi_free()
when tearing down the rawmidi interface. So we shouldn't try to free it
in snd_usbmidi_create() after having registered the rawmidi interface.

Fix the RC QPs send queue overhead computation to take into account

operations.
The ATOMIC and UMR segments can't coexist together, so chose maximum out

states, but added the code to UC transport.

Changes from v4:
- as suggested by Doug Ledford, optimized spinlock usage,
i.e. ipoib_mcast_join() is called with lock held.
Changes from v3:
- sync with priv->lock before flag check.
Chages from v2:
- Move check for OPER_UP flag state to mcast_join() to
ensure no event worker is in progress.
- minor style fixes.
Changes from v1:

ASoC: Fixes for v4.5
A rather large batch of fixes here, almost all in the Intel driver.
The changes that got merged in this merge window for Skylake were rather
large and as well as issues that you'd expect in a large block of new
code there were some problems created for older processors which needed
fixing up. Things are largely settling down now hopefully.

This patch fixes vulnerability CVE-2016-2085. The problem exists
because the vm_verify_hmac() function includes a use of memcmp().
Unfortunately, this allows timing side channel attacks; specifically
a MAC forgery complexity drop from 2^128 to 2^12. This patch changes
the memcmp() to the cryptographically safe crypto_memneq().

MMUv4 supports 2 concurrent page sizes: Normal and Super [4K to 16M]
So far Linux supported a single super page size for a given Normal page,
depending on the software page walking address split.
e.g. we had 11:8:13 address split for 8K page, which meant super page
was 2 ^(8+13) = 2M (given that THP size has to be PMD_SHIFT)
Now we turn this around, by allowing multiple Super Pages in Kconfig
(currently 2M and 16M only) and forcing page walker address split to
PGDIR_SHIFT and PAGE_SHIFT
For configs without Super page, things are same as before and
PGDIR_SHIFT can be hacked to get non default address split
The motivation for this change is a customer who needs 16M super page
and a 8K Normal page combo.

The pfn_t type uses an unsigned long to store a pfn + flags value. On a
64-bit platform the upper 12 bits of an unsigned long are never used for
storing the value of a pfn. However, this is not true on highmem
platforms, all 32-bits of a pfn value are used to address a 44-bit
physical address space. A pfn_t needs to store a 64-bit value.

Mike said:
: CONFIG_UBSAN_ALIGNMENT breaks x86-64 kernel with lockdep enabled, i. e
: kernel with CONFIG_UBSAN_ALIGNMENT fails to load without even any error
: message.
:
: The problem is that ubsan callbacks use spinlocks and might be called
: before lockdep is initialized. Particularly this line in the
: reserve_ebda_region function causes problem:
:
: lowmem = *(unsigned short *)__va(BIOS_LOWMEM_KILOBYTES);
:
: If i put lockdep_init() before reserve_ebda_region call in
: x86_64_start_reservations kernel loads well.
Fix this ordering issue permanently: change lockdep so that it uses
hlists for the hash tables. Unlike a list_head, an hlist_head is in its
initialized state when it is all-zeroes, so lockdep is ready for
operation immediately upon boot - lockdep_init() need not have run.
The patch will also save some memory.
lockdep_init() and lockdep_initialized can be done away with now - a 4.6
patch has been prepared to do this.

This showed up on ARC when running LMBench bw_mem tests as Overlapping
TLB Machine Check Exception triggered due to STLB entry (2M pages)
overlapping some NTLB entry (regular 8K page).
bw_mem 2m touches a large chunk of vaddr creating NTLB entries. In the
interim khugepaged kicks in, collapsing the contiguous ptes into a
single pmd. pmdp_collapse_flush()->flush_pmd_tlb_range() is called to
flush out NTLB entries for the ptes. This for ARC (by design) can only
shootdown STLB entries (for pmd). The stray NTLB entries cause the
overlap with the subsequent STLB entry for collapsed page. So make
pmdp_collapse_flush() call pte flush interface not pmd flush.
Note that originally all thp flush call sites in generic code called
flush_tlb_range() leaving it to architecture to implement the flush for
pte and/or pmd. Commit 12ebc1581ad11454 changed this by calling a new
opt-in API flush_pmd_tlb_range() which made the semantics more explicit
but failed to distinguish the pte vs pmd flush in generic code, which is
what this patch fixes.
Note that ARC can fixed w/o touching the generic pmdp_collapse_flush()
by defining a ARC version, but that defeats the purpose of generic
version, plus sementically this is the right thing to do.
Fixes STAR 9000961194: LMBench on AXS103 triggering duplicate TLB
exceptions with super pages
Fixes: 12ebc1581ad11454 ("mm,thp: introduce flush_pmd_tlb_range")

DAX implements split_huge_pmd() by clearing pmd. This simple approach
reduces memory overhead, as we don't need to deposit page table on huge
page mapping to make split_huge_pmd() never-fail. PTE table can be
allocated and populated later on page fault from backing store.
But one side effect is that have to check if pmd is pmd_none() after
split_huge_pmd(). In most places we do this already to deal with
parallel MADV_DONTNEED.
But I found two call sites which is not affected by MADV_DONTNEED (due
down_write(mmap_sem)), but need to have the check to work with DAX
properly.

The kptr_restrict flag, when set to 1, only prints the kernel address
when the user has CAP_SYSLOG. When it is set to 2, the kernel address
is always printed as zero. When set to 1, this needs to check whether
or not we're in IRQ.
However, when set to 2, this check is unneccessary, and produces
confusing results in dmesg. Thus, only make sure we're not in IRQ when
mode 1 is used, but not mode 2.
