We tried linking in a single built object to hold the device table,
but only works if all of the sparc64 crypto modules get built the same
way (modular vs. non-modular).
Just include the device ID stub into each driver source file so that
the table gets compiled into the correct result in all cases.

Sparc32 already supported it, as a consequence of using the
generic atomic64 implementation. And the sparc64 implementation
is rather trivial.
This allows us to set ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE for all
of sparc, and avoid the annoying warning from lib/atomic64_test.c

for sparc again
This bug-fix makes sure that of_address_to_resource is defined extern for sparc
so that the sparc-specific implementation of of_address_to_resource() is once
again used when including include/linux/of_address.h in a sparc context. A
number of drivers in mainline relies on this function working for sparc.
The bug was introduced in a850a7554442f08d3e910c6eeb4ee216868dda1e, "of/address:
add empty static inlines for !CONFIG_OF". Contrary to that commit title, the
static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never
defined for sparc. This is good behavior for the other functions in
include/linux/of_address.h, as the extern functions defined in
drivers/of/address.c only gets linked when OF_ADDRESS is configured. However,
for of_address_to_resource there exists a sparc-specific implementation in
arch/sparc/arch/sparc/kernel/of_device_common.c

This adds sparc support for platform_get_irq that in the normal case use
platform_get_resource() to get an irq. This standard approach fails for sparc as
there are no resources of type IORESOURCE_IRQ for irqs for sparc.
Cross platform drivers can then use this standard platform function and work on
sparc instead of having to have a special case for sparc.

If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.
For example:
~# ifconfig eth0 down
~# echo disk > /sys/power/state
<trigger a restore from hibernation>
~# ifconfig eth0 up
SIOCSIFFLAGS: No such device
This happens because the restore function bails out early upon
finding devices that were not up at hibernation. In doing so,
it never gets to the netif_device_attach call at the end of
the restore function. Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

when something goes wrong, a flood of these messages can be
generated by usbnet (thousands per second). This doesn't
generally *help* the condition so this patch ratelimits the
rate of their generation.
There's an underlying problem in usbnet's kevent deferral
mechanism which needs fixing, specifically that events *can*
get dropped and not handled. This patch doesn't address this,
but just mitigates fallout caused by the current implemention.

When pairing fails due to wrong confirm value, the management layer
doesn't report a proper error status. It sends
MGMT_STATUS_CONNECT_FAILED instead of MGMT_STATUS_AUTH_FAILED.
Most of management functions that receive a status as a parameter
expects for it to be encoded as a HCI status. But when a SMP pairing
fails, the SMP layer sends the SMP reason as the error status to the
management layer.
This commit maps all SMP reasons to HCI_ERROR_AUTH_FAILURE, which will
be converted to MGMT_STATUS_AUTH_FAILED in the management layer.

The mgmt_read_index_list uses one loop to calculate the max needed size
of its response with the help of an upper-bound of the controller count.
The second loop is more strict as it checks for HCI_SETUP (which might
have gotten set after the first loop) and could result in some indexes
being skipped. Because of this the function needs to readjust the event
length and index count after filling in the response array.

jffs2_write_begin() first acquires the page lock, then f->sem. This
causes an AB-BA deadlock with jffs2_garbage_collect_live(), which first
acquires f->sem, then the page lock:
jffs2_garbage_collect_live
mutex_lock(&f->sem) (A)
jffs2_garbage_collect_dnode
jffs2_gc_fetch_page
read_cache_page_async
do_read_cache_page
lock_page(page) (B)
jffs2_write_begin
grab_cache_page_write_begin
find_lock_page
lock_page(page) (B)
mutex_lock(&f->sem) (A)
We fix this by restructuring jffs2_write_begin() to take f->sem before
the page lock. However, we make sure that f->sem is not held when
calling jffs2_reserve_space(), as this is not permitted by the locking
rules.
The deadlock above was observed multiple times on an SoC with a dual
ARMv7 (Cortex-A9), running the long-term 3.4.11 kernel; it occurred
when using scp to copy files from a host system to the ARM target
system. The fix was heavily tested on the same target system.

That error blocks I/O in some cases as -EINTR error was returned

configure hardware to sleep mode on every case after tuning is
stopped. That kind of behavior blocks it, leaving hardware some
unwanted state in worst case.
That error was seen every time when af9015 was plugged to USB1.1

For non MIPSr2 processors, such as the BMIPS 5000, calls to
arch_local_irq_disable() and others may be preempted, and in doing
so a stale value may be restored to c0_status. This fix disables
preemption for such processors prior to the call and enables it
after the call.
Those functions that needed this fix have been "outlined" to
mips-atomic.c, as they are no longer good candidates for inlining.
This bug was observed in a BMIPS 5000, occuring once every few hours
in a continuous reboot test. It was traced to the write_lock_irq()
function which was being invoked in release_task() in exit.c.
By placing a number of "nops" inbetween the mfc0/mtc0 pair in
arch_local_irq_disable(), which is called by write_lock_irq(), we
were able to greatly increase the occurance of this bug. Similarly,
the application of this commit silenced the bug.

So far is_compat_task() was testing for 32-bit registers if O32 support
was enabled and if O32 support was disabled but N32 enabled it was testing
for 32-bit address space. So if both O32 and N32 were enabled a N32
task was not considered a compat task, whops.
This still leaves potential cases where O32 and N32 need different treatment
unsolved. But that's another commit.

All the headers but kvm_para.h use the Kbuild infrastructure to
get to the asm-generic headers.

between native and cross compiler
For kernel/bound.c being compiled by native compiler, it will generate following errors in gcc 4.4.3:
CC kernel/bounds.s
In file included from include/linux/bug.h:4,
from include/linux/page-flags.h:9,
from kernel/bounds.c:9:
arch/unicore32/include/asm/bug.h:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
arch/unicore32/include/asm/bug.h:23: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
So, we moved definitions in asm/bug.h to arch/unicore32/kernel/setup.h to solve the problem.

When disintegrate system.h, I left an error in asm/cmpxchg.h, which

Because our PCI-bus handler confines dma zone into 128M, we should add
CONFIG_ZONE_DMA for all boards. Otherwise, all memory bigger than 128M
will be pushed into ZONE_MOVABLE.

Commit d065bd810b6deb67d4897a14bfe21f8eb526ba99
(mm: retry page fault when blocking on disk transfer) and
commit 37b23e0525d393d48a7d59f870b3bc061a30ccdb
(x86,mm: make pagefault killable)
The above commits introduced changes into the x86 pagefault handler
for making the page fault handler retryable as well as killable.
These changes reduce the mmap_sem hold time, which is crucial
during OOM killer invocation.
Port these changes to unicore32.

If the cipher suites need to be allocated, but this
allocation fails, this leaks the internal scan request.
Fix that by going to the correct error handling label.
