Add support in the NFIT BLK I/O path for the "latch" flag
defined in the "Get Block NVDIMM Flags" _DSM function:
http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf
This flag requires the driver to read back the command register after it
is written in the block I/O path. This ensures that the hardware has
fully processed the new command and moved the aperture appropriately.

Update the nfit block I/O path to use the new PMEM API and to adhere to
the read/write flows outlined in the "NVDIMM Block Window Driver
Writer's Guide":
http://pmem.io/documents/NVDIMM_Driver_Writers_Guide.pdf
This includes adding support for targeted NVDIMM flushes called "flush
hints" in the ACPI 6.0 specification:
http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf
For performance and media durability the mapping for a BLK aperture is
moved to a write-combining mapping which is consistent with
memcpy_to_pmem() and wmb_blk().

In preparation for fixing the BLK path to properly use "directed
pcommit" enable the unit test infrastructure to emit mock "flush"
tables. Writes to these flush addresses trigger a memory controller to
flush its internal buffers to persistent media, similar to the x86

We currently set x27 in compat_sys_sigreturn_wrapper and
compat_sys_rt_sigreturn_wrapper, similarly to what we do with r8/why on
32-bit ARM, in an attempt to prevent sigreturns from being restarted.
However, on arm64 we have always used pt_regs::syscallno for syscall
restarting (for both native and compat tasks), and x27 is never
inspected again before being overwritten in kernel_exit.
This patch removes the pointless register assignments.

Implement the mips_cdmm_phys_base() platform callback to provide a
default Common Device Memory Map (CDMM) physical base address for the
Pistachio SoC. This allows the CDMM in each VPE to be configured and
probed for devices, such as the Fast Debug Channel (FDC).
The physical address chosen is just below the default CPC address, which
appears to also be unallocated.
The FDC IRQ is also usable on Pistachio, and is routed through the GIC,
so implement the get_c0_fdc_int() platform callback using
gic_get_c0_fdc_int(), so the FDC driver doesn't have to fall back to
polling.

Wider testing reveals that the Fast Debug Channel (FDC) interrupt is
routed through the GIC just fine on Pistachio SoC, even though it
contains interAptiv cores. Clearly the FDC interrupt routing problems
previously observed on interAptiv and proAptiv cores are specific to the
Malta FPGA bitstreams.
Move the workaround for interAptiv and proAptiv out of
gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's
get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use
the FDC interrupt.

MT_SMP is not the only SMP option for MT cores. The MT_SMP option
allows more than one VPE per core to appear as a secondary CPU in the
system. Because of how CM works, it propagates the address-based
cache ops to the secondary cores but not the index-based ones.
Because of that, the code does not use IPIs to flush the L1 caches on
secondary cores because the CM would have done that already. However,
the CM functionality is independent of the type of SMP kernel so even in
non-MT kernels, IPIs are not necessary. As a result of which, we change
the conditional to depend on the CM presence. Moreover, since VPEs on
the same core share the same L1 caches, there is no need to send an
IPI on all of them so we calculate a suitable cpumask with only one
VPE per core.

The pointer to an AFU in the adapter's list of AFUs can be null
if we're in the process of removing AFUs. The afu_list_lock
doesn't guard against this.
Say we have 2 slices, and we're in the process of removing cxl.
- We remove the AFUs in order (see cxl_remove). In cxl_remove_afu
for AFU 0, we take the lock, set adapter->afu[0] = NULL, and
release the lock.
- Then we get an slbia. In cxl_slbia we take the lock, and set
afu = adapter->afu[0], which is NULL.
- Therefore our attempt to check afu->enabled will blow up.
Therefore, check if afu is a null pointer before dereferencing it.

Pull Ceph fixes from Sage Weil:
"There is a fix for CephFS and RBD when used within containers/namespaces,

There are also two patches updating MAINTAINERS. One breaks out the

The goal here is to move closer to a situation where Ilya Dryomov or

At present we don't create efficient ebitmaps when importing NetLabel
category bitmaps. This can present a problem when comparing ebitmaps
since ebitmap_cmp() is very strict about these things and considers
these wasteful ebitmaps not equal when compared to their more
efficient counterparts, even if their values are the same. This isn't
likely to cause problems on 64-bit systems due to a bit of luck on
how NetLabel/CIPSO works and the default ebitmap size, but it can be
a problem on 32-bit systems.
This patch fixes this problem by being a bit more intelligent when
importing NetLabel category bitmaps by skipping over empty sections
which should result in a nice, efficient ebitmap.

The firmware class uevent function accessed the "fw_priv->buf" buffer

(looks like it goes back to 2012 and commit 1244691c73b2: "firmware

only now in 4.2-rc1.
Shuah Khan is trying to bisect what it is that causes this to trigger

Reading page fault handler code I've noticed that under right
circumstances kernel would map anonymous pages into file mappings: if
the VMA doesn't have vm_ops->fault() and the VMA wasn't fully populated
on ->mmap(), kernel would handle page fault to not populated pte with
do_anonymous_page().
Let's change page fault handler to use do_anonymous_page() only on
anonymous VMA (->vm_ops == NULL) and make sure that the VMA is not
shared.
For file mappings without vm_ops->fault() or shred VMA without vm_ops,
page fault on pte_none() entry would lead to SIGBUS.

addr_is_blank() should return true if family is neither AF_INET nor
AF_INET6. This is what its counterpart entity_addr_t::is_blank_ip() is
doing and it is the right thing to do: in process_banner() we check if
our address is blank and if it is "learn" it from our peer. As it is,
we never learn our address and always send out a blank one. This goes
way back to ceph.git commit dd732cbfc1c9 ("use sockaddr_storage; and
some ipv6 support groundwork") from 2009.
While at at, do not open-code ipv6_addr_any() and use INADDR_ANY

Take a GEM reference for and pin the new cursor BO, unpin and drop the
GEM reference for the old cursor BO in radeon_crtc_cursor_set2, and use
radeon_crtc->cursor_addr in radeon_set_cursor.
This fixes radeon_cursor_reset accidentally incrementing the cursor BO
pin count, and cleans up the code a little.
