There is a missing curly brace here so we might print some extra debug

Commit 198d208df4371734ac4728f69cb585c284d20a15 ("x86: Keep
thread_info on thread stack in x86_32") made 32-bit kernels use
kernel_stack to point to thread_info. That change missed a couple of
updates needed by Xen's 32-bit PV guests:
1. kernel_stack needs to be initialized for secondary CPUs
2. GET_THREAD_INFO() now uses %fs register which may not be the
kernel's version when executing xen_iret().
With respect to the second issue, we don't need GET_THREAD_INFO()
anymore: we used it as an intermediate step to get to per_cpu xen_vcpu
and avoid referencing %fs. Now that we are going to use %fs anyway we
may as well go directly to xen_vcpu.

I hit another BUG_ON with e240c1839d11152b0355442. In __get_priority_stripe(),
stripe count equals to 0 initially. Between atomic_inc and BUG_ON,
get_active_stripe() finds the stripe. So the stripe count isn't 1 any more.
V2: keeps the BUG_ON suggested by Neil.

Pull fbdev renaming patches from Tomi Valkeinen:
"Reorder drivers/video/ directory so that all fbdev drivers are now
located in drivers/video/fbdev/ and the fbdev framework core files are
located in drivers/video/fbdev/core/

menu options are in separate submenus, instead of both being mixed in
the same 'Graphics support' menu level"

At the moment the "Device Drivers / Graphics support" kernel config page
looks rather messy, with DRM and fbdev driver selections on the same
page, some on the top level Graphics support page, some under their
respective subsystems.
If I'm not mistaken, this is caused by the drivers depending on other
things than DRM or FB, which causes Kconfig to arrange the options in
not-so-neat manner.
Both DRM and FB have a main menuconfig option for the whole DRM or FB
subsystem. Optimally, this would be enough to arrange all DRM and FB
options under the respective subsystem, but for whatever reason this
doesn't work reliably.
This patch adds an explicit submenu for DRM and FB, making it much
clearer which options are related to FB, and which to DRM.

Instead of having fbdev framework core files at the root fbdev
directory, mixed with random fbdev device drivers, move the fbdev core
files to a separate core directory. This makes it much clearer which of
the files are actually part of the fbdev framework, and which are part
of device drivers.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

Steve reported a reboot hang and bisected it back to this commit:
a4f1987e4c54 x86, reboot: Add EFI and CF9 reboot methods into the default list
He heroically tested all reboot methods and found the following:
reboot=t # triple fault ok
reboot=k # keyboard ctrl FAIL
reboot=b # BIOS ok
reboot=a # ACPI FAIL
reboot=e # EFI FAIL [system has no EFI]
reboot=p # PCI 0xcf9 FAIL
And I think it's pretty obvious that we should only try PCI 0xcf9 as a
last resort - if at all.
The other observation is that (on this box) we should never try
the PCI reboot method, but close with either the 'triple fault'
or the 'BIOS' (terminal!) reboot methods.
Thirdly, CF9_COND is a total misnomer - it should be something like
CF9_SAFE or CF9_CAREFUL, and 'CF9' should be 'CF9_FORCE' ...
So this patch fixes the worst problems:
- it orders the actual reboot logic to follow the reboot ordering
pattern - it was in a pretty random order before for no good
reason.
- it fixes the CF9 misnomers and uses BOOT_CF9_FORCE and
BOOT_CF9_SAFE flags to make the code more obvious.
- it tries the BIOS reboot method before the PCI reboot method.
(Since 'BIOS' is a terminal reboot method resulting in a hang
if it does not work, this is essentially equivalent to removing
the PCI reboot method from the default reboot chain.)
- just for the miraculous possibility of terminal (resulting
in hang) reboot methods of triple fault or BIOS returning
without having done their job, there's an ordering between
them as well.

When we build an already built kernel again, arch/x86/syscalls/Makefile
and arch/x86/tools/Makefile emits "Nothing to be done for ..."
messages.
Here is the command log:
$ make defconfig
[ snip ]
$ make
[ snip ]
$ make
make[1]: Nothing to be done for `all'. <-----
make[1]: Nothing to be done for `relocs'. <-----
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
Besides not emitting those, "all" and "relocs" should be added to PHONY as well.

Have the KB(),MB(),GB() macros produce unsigned longs to avoid
unintended sign extension issues with the gen2 memory size
detection.
What happens is first the uint8_t returned by
read_pci_config_byte() gets promoted to an int which gets
multiplied by another int from the MB() macro, and finally the
result gets sign extended to size_t.
Although this shouldn't be a problem in practice as all affected
gen2 platforms are 32bit AFAIK, so size_t will be 32 bits.

Running:

make O=dir kvmconfig
the second command dirties the source tree with file ".config",
symlink "source" and objects in folder "scripts".
Fixed by using properly prefixed paths in the arch Makefile.

perf stat did initialize the stats structure used to compute
stddev etc. incorrectly. It merely zeroes it. But one member
(min) needs to be set to a non zero value. This causes min
to be not computed at all. Call init_stats() correctly.
It doesn't matter for stat currently because it doesn't use
min, but it's still better to do it correctly.
The other users of statistics are already correct.

Currently,
$ perf bench numa mem
errors out with usage information. To make this more user-friendly, let
us provide a minimum set of default values required for a test
run. As an added bonus,
$ perf bench all
now goes all the way to completion.

At the end of

the program segfaults because it attempts to dereference a NULL

The dwarf_getcfi() only checks .debug_frame section for CFI, but as
most binaries only have .eh_frame it'd return NULL and it makes
some variables inaccessible.
Using dwarf_getcfi_elf (along with dwarf_getelf()) allows to show and
add probe to more variables.

As Namhyung reported(https://lkml.org/lkml/2014/4/1/89),
current perf-probe -L option doesn't handle errors in line-range
searching correctly. It causes a SEGV if an error occured in the
line-range searching.
----
$ perf probe -x ./perf -v -L map__load
Open Debuginfo file: /home/namhyung/project/linux/tools/perf/perf
fname: util/map.c, lineno:153
New line range: 153 to 2147483647
path: (null)
Segmentation fault (core dumped)
----
This is because line_range_inline_cb() ignores errors
from find_line_range_by_line() which means that lr->path is
already freed on the error path in find_line_range_by_line().
As a result, get_real_path() accesses the lr->path and it
causes a NULL pointer exception.
This fixes line_range_inline_cb() to handle the error correctly,
and report it to the caller.
Anyway, this just fixes a possible SEGV bug, Namhyung's patch
is also required.

The commit 5a62257a3ddd1 ("perf probe: Replace line_list with
intlist") replaced line_list to intlist but it has a problem that if a
same line was added again, it'd return -EEXIST rather than 1.
Since line_range_walk_cb() only checks the result being negative, it
resulted in failure or segfault sometimes.

The Makefile logic sets FEATURE_CHECKS_CFLAGS-libdw-dwarf-unwind and
FEATURE_CHECKS_LDFLAGS-libdw-dwarf-unwind only if LIBDW_DIR is
defined. This means that under a normal setup,
$ make NO_LIBUNWIND=1
won't automatically pick up libdw. Fix this.

The patch 3a3ffa2e82205 ("tools lib traceevent: Report better error
message on bad function args") added the error message but it seems
there's no reason to call warning() directly.
So change it to do_warning_event() to provide event information too.

It turns out all Haswell processors (including the Desktop
variant) support RAPL DRAM readings in addition to package,
pp0, and pp1.
I've confirmed RAPL DRAM readings on my model 60 Haswell
desktop.
See the 4th-gen-core-family-desktop-vol-2-datasheet.pdf
available from the Intel website for confirmation.

We are flagging the parent IRQ as chained, then we must also

Pull liblockdep fixes from Sasha Levin:
" 1. There was a build breakage caused by marking a function 'asmlinkage'
in lockdep.h. Fix that by ignoring asmlinkage and visible annotations.
2. Josh Boyer mentioned that Fedora would like to include liblockdep
as a package, so we had to fix our versioning methods from being dumb
and pointless to something actually usable. So now liblockdep.so tracks
the kernel version which makes lives of distro folks much easier. "

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added
asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep.
Since we don't need asmlinkage in liblockep, just ignore it.

DSS uses shared irq handlers for DISPC and DSI, because on OMAP3, the
DISPC and DSI share the same irq line.
However, the irq handlers presume that the hardware is enabled, which,
in theory, may not be the case with shared irq handlers. So if an
interrupt happens while the DISPC/DSI is off, the kernel will halt as
the irq handler tries to access the DISPC/DSI registers.
In practice that should never happen, as both DSI and DISPC are in the
same power domain. So if there's an IRQ for one of them, the other is
also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will
generate a spurious IRQ, which then causes the problem.
This patch adds an is_enabled field for both DISPC and DSI, which is
used to track if the HW is enabled. For DISPC the code is slightly more
complex, as the users of DISPC can register the interrupt handler, and
we want to hide the is_enabled handling from the users of DISPC.

FB driver uses lowlevel controls for LCD powering and contrast changing.
Since LCD class cannot be used as an optional feature and should be
compiled for using in the driver, this patch selects LCD_CLASS_DEVICE
symbol for the driver.

"clk: divider: fix rate calculation for fractional rates" patch (and
similar for TI specific divider) fixes the clk-divider's rounding. This
patch updates the DSS driver to round the rates accordingly.
This fixes the DSS's warnings about clock rate mismatch, and also fixes
the wrong fclk rate being set.
