ARM: 6740/1: Place correctly notes section in the linker script
Commit
18991197b4b588255ccabf472ebc84db7b66a19c added --build-id

reason places the section at 0 when linker script doesn't mention it

The
1e621a8e3752367d4aae78a8ab00a18fb2793f34 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.
This problem was discussed here:

http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.
This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).
It is enough to place it correctly in vmlinux (so debuggers are happy):

ARM: 6741/1: errata: pl310 cache sync operation may be faulty
The effect of cache sync operation is to drain the store buffer and
wait for all internal buffers to be empty. In normal conditions, store
buffer is able to merge the normal memory writes within its 32-byte
data buffers. Due to this erratum present in r3p0, the effect of cache
sync operation on the store buffer still remains when the operation
completes. This means that the store buffer is always asked to drain
and this prevents it from merging any further writes.
This can severely affect performance on the write traffic esp. on
Normal memory NC one.
The proposed workaround is to replace the normal offset of cache sync
operation(0x730) by another offset targeting an unmapped PL310
register 0x740.

Expand CONFIG_DEBUG_LIST to several other list operations
When list debugging is enabled, we aim to readably show list corruption
errors, and the basic list_add/list_del operations end up having extra
debugging code in them to do some basic validation of the list entries.
However, "list_del_init()" and "list_move[_tail]()" ended up avoiding

IB/qib: Prevent double completions after a timeout or RNR error
There is a double completion associated with error handling for RC QPs.
The sequence is:
- The do_rc_ack() routine fields an RNR nack and there are 0
rnr_retries configured on the QP.
- qib_error_qp() stops the pending timer
- qib_rc_send_complete() is called from sdma_complete()
- qib_rc_send_complete() starts the timer because the msb of the psn
just completed says an ack is needed.
- a bunch of flushes occur as ipoib posts WQEs to an error'ed QP
- rc_timeout() calls qib_restart_rc()
- qib_restart_rc() calls qib_send_complete() with a

844a391799c2 ("nothing in
do_follow_link() is going to see RCU"), he mistakenly left the

be _after_ dropping RCU, since the dentry isn't necessarily stable
otherwise.
So complete the code movement in that commit, and move the BUG_ON() into
do_follow_link() too. This means that we need to pass in 'inode' as an
argument (just for this one use), but that's a small thing. And
eventually we may be confident enough in our path lookup that we can
just remove the BUG_ON() and the unnecessary inode argument.

This also optmizes away some harmless but unnecessary setting of

Doing NMI startup as an early initcall doesn't work because we need
to have SMP started up by then.
So we'd only NMI startup one cpu, which causes perf PMU grab to
BUG because the nmi_active count isn't what it's supposed to be.

spi/pxa2xx pci: fix the release - remove race
Right now the platform device and its platform data is included in one big
struct which requires its custom ->release function. The problem with the
release function within the driver is that it might be called after the
driver was removed because someone was holding a reference to it and it
was not called right after platform_device_unregister(). So we also free
the platform device memory to which one might hold a reference.
This patch uses the normal pdev functions so this kind of race does not
occur.
