e92e1d0d78 MIPS: Netlogic: Core wakeup improvements
Move wakeup to after early console. This will allow us to display error
messages when cores are not woken up.  Also reduce the wait time for core
to come up.

194d315da8 MIPS: Netlogic: Remove XLR early serial setup
The early serial code is not needed because we already have early
printk support provided by common/earlycons.c

This change also fixes the following build error that occurs when
CONFIG_SERIAL_8250 is not configured for Netlogic XLR boards:

arch/mips/built-in.o: In function `nlm_early_serial_setup':

c24a8a7a99 MIPS: Netlogic: Add MSI support for XLP
Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

27547abf36 MIPS: malta: Incorporate PIIX4 ACPI I/O region in PCI controller resources
Boot log says:

pci 0000:00:0a.3: no compatible bridge window for [io  0x1000-0x103f]
pci 0000:00:0a.3: no compatible bridge window for [io  0x1100-0x110f]

The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.

This patch actually reverts the change made by c5de50dada. And with this
fix, log says:

pci 0000:00:0a.3: quirk: [io  0x1000-0x103f] claimed by PIIX4 ACPI
pci 0000:00:0a.3: quirk: [io  0x1100-0x110f] claimed by PIIX4 SMB

These things may not be used but as part of platform resources are better
off to be included.

7c71ee7803 xfs: allow logical-sector sized O_DIRECT
Some time ago, mkfs.xfs started picking the storage physical
sector size as the default filesystem "sector size" in order
to avoid RMW costs incurred by doing IOs at logical sector
size alignments.

However, this means that for a filesystem made with i.e.
a 4k sector size on an "advanced format" 4k/512 disk,
512-byte direct IOs are no longer allowed.  This means
that XFS has essentially turned this AF drive into a hard
4K device, from the filesystem on up.

XFS's mkfs-specified "sector size" is really just controlling
the minimum size & alignment of filesystem metadata.

There is no real need to tightly couple XFS's minimal
metadata size to the minimum allowed direct IO size;
XFS can continue doing metadata in optimal sizes, but
still allow smaller DIOs for apps which issue them,
for whatever reason.

This patch adds a new field to the xfs_buftarg, so that
we now track 2 sizes:

 1) The metadata sector size, which is the minimum unit and
    alignment of IO which will be performed by metadata operations.
 2) The device logical sector size

The first is used internally by the file system for metadata
alignment and IOs.
The second is used for the minimum allowed direct IO alignment.

This has passed xfstests on filesystems made with 4k sectors,
including when run under the patch I sent to ignore
XFS_IOC_DIOINFO, and issue 512 DIOs anyway.  I also directly
tested end of block behavior on preallocated, sparse, and
existing files when we do a 512 IO into a 4k file on a 
4k-sector filesystem, to be sure there were no unexpected
behaviors.

85ba7b7d39 Revert "drm/i915: Mask reserved bits in display/sprite address registers"
This reverts commit 446f254566.

I've left the masking in the pageflip code since that seems to be some
useful piece of preemptive robustness.

Iirc I've merged this patch under the assumption that the BIOS leaves
some random gunk in the lower bits and gets unhappy if we trample on
them. We have quite a few case like this, so this made sense.

Now I've just learned that there's actual hardware features bits in
the low 12 bits, and the kernel needs to preserve them to allow a
userspace blob to do its job. Given Dave Airlie's clear stance on
userspace blob drivers I've quickly chatted with him and he doesn't
seem too happy. So let's revert this.

If there are indeed bits that we must preserve in this range then we
can ressurrect this patch, but with proper documentation for those
bits supplied. And we probably also need to think a bit about
interactions with our driver.

fb4a96029c arm64: kernel: fix per-cpu offset restore on resume
The introduction of percpu offset optimisation through tpidr_el1 in:

Commit id :7158627686
"arm64: percpu: implement optimised pcpu access using tpidr_el1"

requires cpu_{suspend/resume} to restore the tpidr_el1 register upon resume
so that percpu variables can be addressed correctly when a CPU comes out
of reset from warm-boot.

This patch fixes cpu_{suspend}/{resume} tpidr_el1 restoration on resume, by
calling the set_my_cpu_offset C API, as it is done on primary and secondary
CPUs on cold boot, so that, even if the register used to store the percpu
offset is changed, the save and restore of general purpose registers does not
have to be updated.

07be038209 s390/hypfs: add interface for diagnose 0x304
To provide access to the set-partition-resource-parameter interface
to user space add a new attribute to hypfs/debugfs:
 * s390_hypsfs/diag_304
The data for the query-partition-resource-parameters command can
be access by a read on the attribute. All other diagnose 0x304
requests need to be submitted via ioctl with CAP_SYS_ADMIN rights.

7e21774db5 The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions of
 existing drivers to the common-clock Device Tree binding, and a few
 non-critical fixes to the framework.
 
 Due to an entirely unnecessary cyclical dependency with the arm-soc tree
 this pull request is broken into two pieces. The second piece will be
 sent out after arm-soc sends you the pull request that merged in core
 support for the HiSilicon 3620 platform. That same pull request from
 arm-soc depends on this pull request to merge in those HiSilicon bits
 without causing build failures.
