It just includes <asm-generic/dma-mapping-broken.h>, which is already
handled by <linux/dma-mapping.h> for the !CONFIG_HAS_DMA case (score sets
CONFIG_NO_DMA=y).
h8300/boot: Use POSIX "$((..))" instead of bashism "$[...]"
On Ubuntu, where /bin/sh -> dash, "make ARCH=h8300 clean" gives:
printf: 1: $[0x00400000+0x00140000]: expected numeric value
Replace the bash-specific "$[...]" by POSIX "$((..))" for arithmetic
expansion to fix this.
Note that according to the bash 4.1 manpage, "$[...]" is deprecated, and
will be removed in upcoming versions of bash.
arch/h8300/include/asm/io.h supports only H83007 (H8/3006,3007), H83068
(H8/3065,3066,3067,3068,3069), and H8S2678 (H8S/2670,2673,2674R,2675,2676)
CPU types.
Hence disable H83002 (H8/3001,3002,3003) and H83048
(H8/3044,3045,3046,3047,3048,3052) CPU support at the Kconfig level.
This fixes build failures in allmodconfig/allyesconfig builds, as these
always choose the first CPU type (H83002), which was unsupported:
arch/h8300/include/asm/io.h:13:2: error: #error UNKNOWN CPU TYPE
arch/h8300/kernel/timer/itu.c and arch/h8300/kernel/timer/tpu.c
only support 0--4 for CONFIG_H8300_ITU_CH resp. H8300_TPU_CH, hence limit
them to that range in Kconfig.
Ten years ago, a mismerge happened, concatenating two slightly different
versions of the same file. As a consequence, <asm-generic/tlb.h> was never
included, leading to a build failure only now:
kernel/cpu/idle.c: In function 'cpu_idle_loop':

Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

"This contains 4 fixes.
The first two fix the case where full RCU debugging is enabled,
enabling function tracing causes a live lock of the system. This is
due to the added debug checks in rcu_dereference_raw() that is used by
the function tracer. These checks are also traced by the function
tracer as well as cause enough overhead to the function tracer to slow
down the system enough that the time to finish an interrupt can take
longer than when the next interrupt is triggered, causing a live lock
from the timer interrupt.
Talking this over with Paul McKenney, we came up with a fix that adds
a new rcu_dereference_raw_notrace() that does not perform these added
checks, and let the function tracer use that.
The third commit fixes a failed compile when branch tracing is
enabled, due to the conversion of the trace_test_buffer() selftest
that the branch trace wasn't converted for.
The forth patch fixes a bug caught by the RCU lockdep code where a
rcu_read_lock() is performed when rcu is disabled (either going to or
from idle, or user space). This happened on the irqsoff tracer as it
calls task_uid(). The fix here was to use current_uid() when possible
that doesn't use rcu locking. Which luckily, is always used when
irqsoff calls this code."

From Shawn Guo, mxs fixes for 3.10:
- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
valid interrupt number, the irq of gpio bank 0. That unnecessary
polling results in the driver not detecting when irq 0x7f is active
which makes the machine effectively dead lock. The fix removes the
interrupt poll loop and allows usage of gpio0 interrupt without an
infinite loop.

From Shawn Guo, imx fixes for 3.10, take 2:
- One device tree fix for all spi node to have per clock added.
The clock is needed by spi driver to calculate bit rate divisor.
The spi node in the current device trees either does not have the
clock or is defined as dummy clock, in which case the driver probe
will fail or spi will run at a wrong bit rate.
- Two imx6q clock fixes, which correct axi_sels and ldb_di_sels.

ARM: exynos: add debug_ll_io_init() call in exynos_init_io()
If the early MMU mapping of the UART happens to get booted out of the
TLB between the start of paging_init() and when we finally re-add the
UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if
we've got early_printk enabled. Avoid this hang by calling
debug_ll_io_init() early.
Without this patch, you can reliably reproduce a hang when early
printk is enabled by adding flush_tlb_all() at the start of
exynos_init_io(). After this patch the hang goes away.

ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is defined
Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.
Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.
With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

tracing: Use current_uid() for critical time tracing
The irqsoff tracer records the max time that interrupts are disabled.
There are hooks in the assembly code that calls back into the tracer when
interrupts are disabled or enabled.
When they are enabled, the tracer checks if the amount of time they
were disabled is larger than the previous recorded max interrupts off
time. If it is, it creates a snapshot of the currently running trace
to store where the last largest interrupts off time was held and how
it happened.

What happened was entering into the user code, the interrupts were enabled
and a max interrupts off was recorded. The trace buffer was saved along with
various information about the task: comm, pid, uid, priority, etc.
The uid is recorded with task_uid(tsk). But this is a macro that uses rcu_read_lock()
to retrieve the data, and this happened to happen where RCU is blind (user_enter).
As only the preempt and irqs off tracers can have this happen, and they both
only have the tsk == current, if tsk == current, use current_uid() instead of
task_uid(), as current_uid() does not use RCU as only current can change its uid.
This fixes the RCU suspicious splat.

xfs: inode unlinked list needs to recalculate the inode CRC
The inode unlinked list manipulations operate directly on the inode
buffer, and so bypass the inode CRC calculation mechanisms. Hence an
inode on the unlinked list has an invalid CRC. Fix this by
recalculating the CRC whenever we modify an unlinked list pointer in
an inode, ncluding during log recovery. This is trivial to do and
results in unlinked list operations always leaving a consistent
inode in the buffer.

xfs: fix log recovery transaction item reordering
There are several constraints that inode allocation and unlink
logging impose on log recovery. These all stem from the fact that
inode alloc/unlink are logged in buffers, but all other inode
changes are logged in inode items. Hence there are ordering
constraints that recovery must follow to ensure the correct result
occurs.
As it turns out, this ordering has been working mostly by chance
than good management. The existing code moves all buffers except
cancelled buffers to the head of the list, and everything else to
the tail of the list. The problem with this is that is interleaves
inode items with the buffer cancellation items, and hence whether
the inode item in an cancelled buffer gets replayed is essentially
left to chance.
Further, this ordering causes problems for log recovery when inode
CRCs are enabled. It typically replays the inode unlink buffer long before
it replays the inode core changes, and so the CRC recorded in an
unlink buffer is going to be invalid and hence any attempt to
validate the inode in the buffer is going to fail. Hence we really
need to enforce the ordering that the inode alloc/unlink code has
expected log recovery to have since inode chunk de-allocation was
introduced back in 2003...

xfs: fix remote attribute invalidation for a leaf
When invalidating an attribute leaf block block, there might be
remote attributes that it points to. With the recent rework of the
remote attribute format, we have to make sure we calculate the
length of the attribute correctly. We aren't doing that in
xfs_attr3_leaf_inactive(), so fix it.

xfs: rework dquot CRCs
Calculating dquot CRCs when the backing buffer is written back just
doesn't work reliably. There are several places which manipulate
dquots directly in the buffers, and they don't calculate CRCs
appropriately, nor do they always set the buffer up to calculate
CRCs appropriately.
Firstly, if we log a dquot buffer (e.g. during allocation) it gets
logged without valid CRC, and so on recovery we end up with a dquot
that is not valid.
Secondly, if we recover/repair a dquot, we don't have a verifier
attached to the buffer and hence CRCs are not calculated on the way
down to disk.
Thirdly, calculating the CRC after we've changed the contents means
that if we re-read the dquot from the buffer, we cannot verify the
contents of the dquot are valid, as the CRC is invalid.
So, to avoid all the dquot CRC errors that are being detected by the
read verifier, change to using the same model as for inodes. That
is, dquot CRCs are calculated and written to the backing buffer at
the time the dquot is flushed to the backing buffer. If we modify
the dquot directly in the backing buffer, calculate the CRC
immediately after the modification is complete. Hence the dquot in
the on-disk buffer should always have a valid CRC.

it frees pages first and invalidates TLBs later.
However now we can get concurrency and stuff goes *bang*.

option vs trying to patch the hole by entangling tlb invalidation with

ACPI / scan: do not match drivers against objects having scan handlers
With the introduction of ACPI scan handlers, an ACPI device object
with an ACPI scan handler attached to it must not be bound to an ACPI
driver any more. Therefore it doesn't make sense to match those
ACPI device objects against a newly registered ACPI driver in
acpi_bus_match(), so make that function return 0 if the device
object passed to it has an ACPI scan handler attached.
This also addresses a regression related to a broken ACPI table in
the BIOS, where it has defined a _ROM method under the PCI root
bridge object. This causes the video module to treat that object
as a display controller device (since only display devices are
supposed to have a _ROM method defined according to the ACPI spec).
As a result, the ACPI video driver binds to the PCI root bridge
object and overwrites the previously assigned driver_data field of
it, causing subsequent calls to acpi_get_pci_dev() to fail.

acpi-cpufreq: set current frequency based on target P-State
Commit 4b31e774 (Always set P-state on initialization) fixed bug

Commit 5a1c0228 (cpufreq: Avoid calling cpufreq driver's target()

this behavior.
This fixes the regression by setting policy->cur based on the CPU's
target frequency rather than the CPU's current reported frequency
(which may be different). This means that the P-State will be set
initially if the CPU's target frequency is different from the
governor's target frequency.

Three regression fixes and one no-lvds quirk update. The regression Egbert
Eich tracked down goes back to 2.6.37 ... ugh. The other two are pretty
minor: One bogus modeset state checker WARN and a patch to prevent X
dying in a SIGBUS after a gpu hang with failed (or not implement as on
gen2/3) gpu reset.
