For the past three years, we have had a #warning in
mach-at91 about the sdram_selfrefresh_enable or
at91sam9_standby functions possibly not working on
at91sam9263. In the meantime a function was added
to do the right thing on at91sam9g45, which looks like
it should also work on '9263.

In preparation for the introduction of MSI support in the IRQ
controller driver, we clarify the implementation of IPI using
additional defines for the manipulation of doorbells. Just like IPIs
are implemented using doorbells, MSIs will also use doorbells, so it
makes sense to do this preparatory cleanup first.

When the Marvell Armada 370/XP support was included in the kernel, the
drivers/irqchip/ directory didn't exist and the minimal infrastructure
in it also didn't exist. Now that we have those things in place, we
move the Armada 370/XP IRQ controller driver from
arch/arm/mach-mvebu/irq-armada-370-xp.c to
drivers/irqchip/irq-armada-370-xp.c.
Note in order to reduce code movement and therefore ease the review of
this patch, we intentionally introduce a forward declaration of
armada_370_xp_handle_irq(). It is in fact not needed because this
handler can now simply be implemented before
armada_370_xp_mpic_of_init(). That will be done in the next commit.

eboot.o and efi_stub_$(BITS).o didn't get added to "targets", and hence
their .cmd files don't get included by the build machinery, leading to
the files always getting rebuilt.
Rather than adding the two files individually, take the opportunity and
add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment
at the top of the file to be shrunk quite a bit.
At the same time, remove a pointless flags override line - the variable
assigned to was misspelled anyway, and the options added are
meaningless for assembly sources.
[ hpa: the patch is not minimal, but I am taking it for -urgent anyway
since the excess impact of the patch seems to be small enough. ]

Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code
to reset nf_trace in nf_reset(). This is wrong and unnecessary.
nf_reset() is used in the following cases:
- when passing packets up the the socket layer, at which point we want to
release all netfilter references that might keep modules pinned while
the packet is queued. nf_trace doesn't matter anymore at this point.
- when encapsulating or decapsulating IPsec packets. We want to continue
tracing these packets after IPsec processing.
- when passing packets through virtual network devices. Only devices on
that encapsulate in IPv4/v6 matter since otherwise nf_trace is not
used anymore. Its not entirely clear whether those packets should
be traced after that, however we've always done that.
- when passing packets through virtual network devices that make the
packet cross network namespace boundaries. This is the only cases
where we clearly want to reset nf_trace and is also what the
original patch intended to fix.
Add a new function nf_reset_trace() and use it in dev_forward_skb() to
fix this properly.

This patch changes GFS2's discard issuing code so that it calls
function sb_issue_discard rather than blkdev_issue_discard. The
code was calling blkdev_issue_discard and specifying the correct
sector offset and sector size, but blkdev_issue_discard expects
these values to be in terms of 512 byte sectors, even if the native
sector size for the device is different. Calling sb_issue_discard
with the BLOCK size instead ensures the correct block-to-512b-sector
translation. I verified that "minlen" is specified in blocks, so
comparing it to a number of blocks is correct.

This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde.
This patch introduced a few races which cannot be easily fixed with a
small follow-up patch. Furthermore, the SoC with the broken hardware
register, which this patch intended to add support for, can only be used
with device trees, which this driver currently does not support.

A recent patch to fix the dm cache target's writethrough mode extended
the bio's front_pad to include a 1056-byte struct dm_bio_details.
Writeback mode doesn't need this, so this patch reduces the
per_bio_data_size to 16 bytes in this case instead of 1096.
The dm_bio_details structure was added in "dm cache: fix writes to
cache device in writethrough mode" which fixed commit e2e74d617e ("dm
cache: fix race in writethrough implementation"). In writeback mode
we avoid allocating the writethrough-specific members of the
per_bio_data structure (the dm_bio_details structure included).

The dm-cache writethrough strategy introduced by commit e2e74d617eadc15
("dm cache: fix race in writethrough implementation") issues a bio to
the origin device, remaps and then issues the bio to the cache device.
This more conservative in-series approach was selected to favor
correctness over performance (of the previous parallel writethrough).
However, this in-series implementation that reuses the same bio to write
both the origin and cache device didn't take into account that the block
layer's req_bio_endio() modifies a completing bio's bi_sector and
bi_size. So the new writethrough strategy needs to preserve these bio
fields, and restore them before submission to the cache device,
otherwise nothing gets written to the cache (because bi_size is 0).
This patch adds a struct dm_bio_details field to struct per_bio_data,
and uses dm_bio_record() and dm_bio_restore() to ensure the bio is
restored before reissuing to the cache device. Adding such a large
structure to the per_bio_data is not ideal but we can improve this
later, for now correctness is the important thing.
This problem initially went unnoticed because the dm-cache test-suite
uses a linear DM device for the dm-cache device's origin device.
Writethrough worked as expected because DM submits a *clone* of the
original bio, so the original bio which was reused for the cache was
never touched.

SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever
supported its use and no libc was using it, so the entire sa-restorer
functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.]
for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid
accidental reuse of the mask bit.
Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear
sa_restorer on execve] adds code that assumes sa_sigaction has an
sa_restorer field, if SA_RESTORER is defined which would break MIPS.
So remove the SA_RESTORER definition before the v3.8.4 merge.

The commit a96102be70 introduced set_isa() where compatible ISA info is
also set aside from the one gets passed in. It means, for example, 1004K
will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like
the following inappropriate:
if (c->isa_level == MIPS_CPU_ISA_M32R1 ||
c->isa_level == MIPS_CPU_ISA_M32R2 ||
c->isa_level == MIPS_CPU_ISA_M64R1 ||
c->isa_level == MIPS_CPU_ISA_M64R2)
This patch fixes it.

CONFIG_SNIPROM was renamed to CONFIG_FW_SNIPROM in v3.8. Let's rename
SNIPROM itself too.

Commit 7517de348663b08a808aff44b5300e817157a568 ("MIPS: Alchemy: Redo
PCI as platform driver") added a reference to CONFIG_DEBUG_PCI. Change
it to CONFIG_PCI_DEBUG, as that is a valid Kconfig macro.
Also add a newline to a debugging printk that this fix enables.

Commit 58b69401c797 [MIPS: Function tracer: Fix broken function tracing]
completely broke the function tracer for 64-bit kernels. The symptom is
a system hang very early in the boot process.
The fix: Remove/fix $sp adjustments for 64-bit case.
