The 'latency timer' of PCI devices, both Type 0 and Type 1,
is setup in architecture-specific code [see: 'pcibios_set_master()'].
There are two approaches being taken by all the architectures - check
if the 'latency timer' is currently set between 16 and 255 and if not
bring it within bounds, or, do nothing (and then there is the
gratuitously different PA-RISC implementation).There is nothing architecture-specific about PCI's 'latency timer' so
this patch pulls its setup functionality up into the PCI core by
creating a generic 'pcibios_set_master()' function using the '__weak'
attribute which can be used by all architectures as a default which,
if necessary, can then be over-ridden by architecture-specific code.No functional change.

After changing all consumers of atomics to include , we
ran into some compile time errors due to this dependency chain:linux/atomic.h
-> asm/atomic.h
-> asm-generic/atomic-long.hwhere atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype. This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.Archs that need need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).Compile tested on i386 and x86_64 with allnoconfig.

Do not trace arch_local_save_flags(), arch_local_irq_*() and friends.
Although they are marked inline, gcc may still make a function out of
them and add it to the pool of functions that are traced by the function
tracer. This can cause undesirable results (kernel panic, triple faults,
etc).Add the notrace notation to prevent them from ever being traced.

Re-architect how we save/restore the gpio/port logic that only pertains
to bf538/bf539 parts by pulling it out of the core code paths and pushing
it out to bf538-specific locations.Signed-off-by: Mike Frysinger
-
The current save logic used in hibernation is to do a MMR load (base +
offset) into a register, and then push that onto the stack. Then when
restoring, pop off the stack into a register followed by a MMR store
(base + offset). These use plenty of 32bit insns rather than 16bit,
are pretty long winded, and full of pipeline bubbles.So, by taking advantage of MMRs that are contiguous, the multi-register
push/pop insn, and register abuse, we can shrink this code considerably.When saving, the new logic does a lot of loads into the data and pointer
registers before executing a single multi-register push insn. Then when
restoring, we do a single multi-register pop insn followed by a lot of
stores. Overall, this allows us to cut the insn count by ~30%, the code
size by ~45%, and drastically reduce the register hazards that trigger
bubbles in the pipeline.Signed-off-by: Mike Frysinger

* setns:
ns: Wire up the setns system callDone as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call -
32bit and 64bit on x86 are tested and working. The rest I have looked
at closely and I can't find any problems.setns is an easy system call to wire up. It just takes two ints so I
don't expect any weird architecture porting problems.While doing this I have noticed that we have some architectures that are
very slow to get new system calls. cris seems to be the slowest where
the last system calls wired up were preadv and pwritev. avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h. frv is
behind with perf_event_open being the last syscall wired up. On h8300
the last system call wired up was epoll_wait. On m32r the last system
call wired up was fallocate. mn10300 has recvmmsg as the last system
call wired up. The rest seem to at least have syncfs wired up which was
new in the 2.6.39.v2: Most of the architecture support added by Daniel Lezcano
v3: ported to v2.6.36-rc4 by: Eric W. Biederman
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall conflicts.
v7: ported to Linus's latest post 2.6.39 tree.> arch/blackfin/include/asm/unistd.h | 3 ++-

The Blackfin arch, like the x86 arch, needs to adjust the PC manually
after a breakpoint is hit as normally this is handled by the remote gdb.
However, rather than starting another arch ifdef mess, create a common
GDB_ADJUSTS_BREAK_OFFSET define for any arch to opt-in via their kgdb.h.Signed-off-by: Mike Frysinger

The BF537 SIC combines the gpio port H mask A interrupts with the
emac rx interrupt, so we need to demux this in software.It also combines the gpio port H mask B and the emac tx interrupts,
and the watchdog and port F mask B interrupts, but since we don't
support mask B yet, just add the defines for now.Signed-off-by: Mike Frysinger
