The bash completion does not support listing options for 'perf
kvm|kmem|mem|lock|sched --<TAB>', where 'kvm|kmem|mem|lock|sched' are
all subcommands of perf.
Example:
Before this patch:
$ perf kvm --<TAB>
$
As shown above, the options of perf kvm does not come out.
After this patch:
$ perf kvm --<TAB>
--alloc --caller --input --line --raw-ip --sort
--verbose
As shown above, the options of perf kvm can come out now.

Commit:
c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on")
removed the definition of IS_X86_64 but not all places using it, with
the consequence that perf-read-vdsox32 would not be built anymore, and
the default lib install directory was 'lib' instead of 'lib64'.
Also needs to go to v3.19.

Several tests that rely on implicit build rules fail to build,
when invoked from the main Makefile kselftest target. These
failures are due to --no-builtin-rules and --no-builtin-variables
options set in the inherited MAKEFLAGS.
--no-builtin-rules eliminates the use of built-in implicit rules
and --no-builtin-variables is for not defining built-in variables.
These two options override the use of implicit rules resulting in
build failures. In addition, inherited LDFLAGS result in build
failures and there is no need to define LDFLAGS. Clear LDFLAGS
and MAKEFLAG when make is invoked from the main Makefile kselftest
target. Fixing this at selftests Makefile avoids changing the main
Makefile and keeps this change self contained at selftests level.

The socfpga.dtsi currently has the wrong interrupt number set for SPI master 1
Trying to use the master without this change results in the kernel boot
process waiting forever for an interrupt that will never occur while
attempting to probe any slave devices configured in the device tree as being
under SPI master 1.
The change works for the Cyclone V, and according to the Arria 5 handbook
should be good there too.

The misc subsystem (which is used for /dev/fuse) initializes private_data to
point to the misc device when a driver has registered a custom open file
operation, and initializes it to NULL when a custom open file operation has
*not* been provided.
This subtle quirk is confusing, to the point where kernel code registers
*empty* file open operations to have private_data point to the misc device
structure. And it leads to bugs, where the addition or removal of a custom open
file operation surprisingly changes the initial contents of a file's
private_data structure.
So to simplify things in the misc subsystem, a patch [1] has been proposed to
*always* set the private_data to point to the misc device, instead of only
doing this when a custom open file operation has been registered.
But before this patch can be applied we need to modify drivers that make the
assumption that a misc device file's private_data is initialized to NULL
because they didn't register a custom open file operation, so they don't rely
on this assumption anymore. FUSE uses private_data to store the fuse_conn and
errors out if this is not initialized to NULL at mount time.
Hence, we now set a file's private_data to NULL explicitly, to be independent
of whatever value the misc subsystem initializes it to by default.

Commit 106937e8ccdc ("of: fix handling of '/' in options for
of_find_node_by_path()") caused a regression in OF handling of
stdout-path. While it fixes some cases which have '/' after the ':', it
breaks cases where there is more than one '/' *before* the ':'.
For example, it breaks this boot string
stdout-path = "/rdb/serial@f040ab00:115200";
So rather than doing sequentialized checks (first for '/', then for ':';
or vice versa), to get the correct behavior we need to check for the
first occurrence of either one of them.
It so happens that the handy strcspn() helper can do just that.

The error code paths that require cleanup use a goto to jump to the
cleanup code and return an error code. However, the error code variable
res, which is initialized to -EINVAL when declared, is then overwritten
with the return value of of_parse_phandle_with_args(), and reused as the
return code from of_irq_parse_one(). This leads to an undetermined error
being returned instead of the expected -EINVAL value. Fix it.

Since fab4085 ("netfilter: log: nf_log_packet() as real unified
interface"), the loginfo structure that is passed to nf_log_packet() is
used to explicitly indicate the logger type you want to use.
This is a problem for people tracing rules through nfnetlink_log since
packets are always routed to the NF_LOG_TYPE logger after the
aforementioned patch.
We can fix this by removing the trace loginfo structures, but that still
changes the log level from 4 to 5 for tracing messages and there may be
someone relying on this outthere. So let's just introduce a new
nf_log_trace() function that restores the former behaviour.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
Some urgent regression fixes to booting failures Exynos DRM occured.
Summary:
- Fix two urgent null pointer dereference bugs in case of enabling
or disabling IOMMU. There was two cases to these issues.
One is that plane->crtc is accessed by exynos_disable_plane()
when device tree binding is broken so device driver tries
to release, which means that the mode set operation isn't invoked yet
so plane->crtc is still NULL and exynos_disable_plane() will access
NULL pointer. This issue is fixed by checking if the plane->crtc
is NULL or not in exynos_disable_plane()
Other is that fimd_wait_for_vblank() is called to avoid from page fault
with IOMMU before the ctx object is created. At this time,
fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc
is still NULL because exynos_drm_crtc_create() isn't called yet.
This issue is fixed by creating a crtc object and setting it to
ctx->crtc prior to fimd_wait_for_vblank() call.
For more details, you can refer to below an e-mail thread,
http://www.spinics.net/lists/linux-samsung-soc/msg42436.html
- Remove unnecessary file not used and fix trivial issues.

When allocating from the reserved tags pool, bt_get() is called with
a NULL hctx. If all tags are in use, the hw queue is kicked to push
out any pending IO, potentially freeing tags, and tag allocation is
retried. The problem is that blk_mq_run_hw_queue() doesn't check for
a NULL hctx. So we avoid it with a simple NULL hctx test.
Tested by hammering mtip32xx with concurrent smartctl/hdparm.

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the GPIO interrupts earlier until I found some suitable pins
to test with. We can mux the MMC card detect and write protect pins
from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that
are also suitable for the MMC subsystem.
This turned out several issues that need to be fixed:
- I set the GPIO type wrong to be compatible with omap3 instead
of omap4. The GPIO controller on dm816x has EOI interrupt
register like omap4 and am335x.
- I got the GPIO interrupt numbers wrong as each bank has two
and we only use one. They need to be set up the same way as
on am335x.
- The gpio banks are missing interrupt controller related
properties.
With these changes the GPIO interrupts can be used with the
MMC card detect pin, so let's wire that up. Let's also mux all
the MMC lines for completeness while at it.
For the first GPIO bank I tested using GPMC lines temporarily
muxed to GPIOs on the dip switch 10.

We should signal connect (pull up dp) after we have already
at peripheral mode, otherwise, the dp may be toggled due to
we reset controller or do disconnect during the initialization
for peripheral, then, the host may be confused during the
enumeration, eg, it finds the reset can't succeed, but the
device is still there, see below error message.

A new uas compatible controller has shown up in some people's devices from
the manufacturer Initio Corporation, this controller needs the US_FL_NO_ATA_1X
quirk to work properly with uas, so add it to the uas quirks table.

radeon_bo_create() calls radeon_ttm_placement_from_domain()
before ttm_bo_init() is called. radeon_ttm_placement_from_domain()
uses the ttm bo size to determine when to select top down
allocation but since the ttm bo is not initialized yet the
check is always false. It only took effect when buffers
were validated later. It also seemed to regress suspend
and resume on some systems possibly due to it not
taking effect in radeon_bo_create().
radeon_bo_create() and radeon_ttm_placement_from_domain()
need to be reworked substantially for this to be optimally
effective. Re-enable it at that point.

Commit b11db6581beaccef8ae9a388ae96074aa5cc144f ("perf tools: Fix build
error on ARCH=i386/x86_64/sparc64") uses sed on ARCH, which triggers a
bug in sequence of sed expression, where 's/arm.*/arm/' will replace
'arm64' to 'arm', causes arm64 building failure.
This patch prevent 'arm64' to be mached for 'arm.*' case.

The EHCI IP only needs the UTMI/UPLL (uclk) and the peripheral (iclk)
clocks to work properly. Remove the useless system clock (fclk).
Avoid calling set_rate on the fixed rate UTMI/IPLL clock and remove
useless IS_ENABLED(CONFIG_COMMON_CLK) tests (all at91 platforms have been
moved to the CCF).
This patch also fixes a bug introduced by 3440ef1 (ARM: at91/dt: fix USB
high-speed clock to select UTMI), which was leaving the usb clock
uninitialized and preventing the OHCI driver from setting the usb clock
rate to 48MHz.
This bug was caused by several things:
1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate
cannot be changed once the clock is prepared
2/ The EHCI driver was retrieving and preparing/enabling the uhpck
clock which was in turn preparing its parent clock (the usb clock),
thus preventing any rate change because of 1/

Since commit 0f04cf8df0b20a97369cb634663fef0578cbf273 ("drm/exynos:
fix wrong pipe calculation for crtc"), fimd_clear_channel() can be
called when is_drm_iommu_supported() returns true. In this case,
the kernel is going to be panicked because crtc is not set yet.

The commit "drm/exynos: remove exynos_plane_dpms" (d9ea6256) removed the
use of the enabled flag, which means that the code may attempt to call
win_enable on a NULL crtc. This results in the following oops on
Arndale:

This patch adds in a check to ensure exynos_crtc is not NULL before it
is dereferenced.
