The timer-sp h/w used on versatile platforms can also be used for other
platforms, so move it to a common location.

Since commit 7a5b4e16c880f8350d255dc188f81622905618c1, simpad devices don't
boot anymore, since platform devices are registered too early. Fix by moving
the registration from map_io to arch_initcall as done on other sa1100 boards.

This patch fixes a nasty initialization condition on the RTSR register.
Sometimes, bit 1 will wake up set, sometimes not. This can be seen
by checking the value of the RTSR by typing '$ cat /proc/driver/rtc',
which has been provided by the previous patch.
If this bit is set, the command '$ cat /dev/rtc0' will lock the system
in an endless interrupt routine calling loop.
This patch fixes the issue both at sa1100_rtc_probe(), where it avoids
a spurious interrupt from happening, and at sa1100_rtc_interrupt(),
which is the robust solution, though it does not avoid the first
spurious interrupt.

There's no need to keep pointers to the ELF sections available while
the module is loaded - we only need the section pointers while we're
finding and registering the unwind tables, which can all be done during
the finalize stage of loading.

* Fix kexec build failure with CONFIG_THUMB2_KERNEL.
* Avoids deprecated/forbidden sp and pc usage in for ARMv7
onwards, retaining compatibility with older architecture
versions.
* The pc value saved to newregs is now aligned on a predictable
instruction boundary.
(stmia { ... pc } or str pc has implementation-defined results
in most versions of the ARM architecutre, and is prohibited
(unpredictable) in Thumb-2.)
* Switch to named inline asm arguments (else I get readily
confused ...)
The resulting code should be compatible with all architecture
versions >= v3, with or without CONFIG_THUMB2_KERNEL.

crash_setup_regs()
Currently, the inline asm is passed &newregs->ARM_r0 as in input,
when modifying multiple fields of newregs.
It's plausible to assume that GCC will assume newregs->ARM_r0 is
modified when passed the address, but unfortunately this assumption
is incorrect.
Also, GCC has no way to guess that the other ARM_r* fields are
modified without the addition of a "memory" clobber.

Allow architectures to redefine this macro if needed. This is useful for
example in architectures where 64-bit ELF vmcores are not supported.
Specifying zero vmcore_elf64_check_arch() allows compiler to optimize
away unnecessary parts of parse_crash_elf64_headers().
We also rename the macro to vmcore_elf64_check_arch() to reflect that it
is used for 64-bit vmcores only.

This patch is the identical GIC demux implementation
merge V3. Instead of implementing same code over and
over simply share it in entry-macro-gic.S. The shared
code is based on the realview implementation.
Each GIC demux instance still has to setup the base address
of the controller using the get_irqnr_preamble macro. The
rest of the GIC specific code can be shared.

Depending on the compiler version, ARM GCC calls the mcount function
either __gnu_mcount_nc or mcount.

arch/arm/kernel/ftrace.c references mcount like kernel/tracing/ftrace.c,
so change the exclusion filter to match any ftrace.o.

The preferred source address is currently ignored for local routes,
which results in all local connections having a src address that is the
same as the local dst address. Fix this by respecting the preferred source
address when it is provided for local routes.
This bug can be demonstrated as follows:
# ifconfig dummy0 192.168.0.1
# ip route show table local | grep local.*dummy0
local 192.168.0.1 dev dummy0 proto kernel scope host src 192.168.0.1
# ip route change table local local 192.168.0.1 dev dummy0 \
proto kernel scope host src 127.0.0.1
# ip route show table local | grep local.*dummy0
local 192.168.0.1 dev dummy0 proto kernel scope host src 127.0.0.1
We now establish a local connection and verify the source IP
address selection:
# nc -l 192.168.0.1 3128 &
# nc 192.168.0.1 3128 &
# netstat -ant | grep 192.168.0.1:3128.*EST
tcp 0 0 192.168.0.1:3128 192.168.0.1:33228 ESTABLISHED
tcp 0 0 192.168.0.1:33228 192.168.0.1:3128 ESTABLISHED

commit bf9ae5386bca8836c16e69ab8fdbe46767d7452a
(llc: use dev_hard_header) removed the
skb_reset_mac_header call from llc_mac_hdr_init.
This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT.
We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns
a meaningful result.

use pskb_may_pull to access ipv6 header correctly for paged skbs
It was omitted in the bridge code leading to crash in blind
__skb_pull
since the skb is cloned undonditionally we also simplify the
the exit path

Commit 3f5a2a713aad28480d86b0add00c68484b54febc zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed. This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example). We don't want SMB or CMB to change during this
operation.
Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

The earlier call to atm_dev_lookup increases the reference count of dev,
so decrease it on the way out.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x, E;
constant C;
@@
x = atm_dev_lookup(...);
... when != false x != NULL
when != true x == NULL
when != \(E = x\|x = E\)
when != atm_dev_put(dev);
*return -C;

Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition. However, 64-bit MIPS configurations
are not detected reliably either.
This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.

Besides -ETIMEDOUT and -EINTR, pci_read_vpd may return other error
values like -ENODEV or -EINVAL which are ignored due to the buggy
check, but the data are not read from VPD anyway and this is checked
subsequently with at most 3 needless loop iterations. This does not
show up as a runtime bug.
