Unlike ipv4_redirect() and ipv4_sk_redirect(), ip_do_redirect()
doesn't call __build_flow_key() directly but via
ip_rt_build_flow_key() wrapper. This leads to __build_flow_key()
getting pointer to IPv4 header of the ICMP redirect packet
rather than pointer to the embedded IPv4 header of the packet
initiating the redirect.
As a result, handling of ICMP redirects initiated by TCP packets
is broken. Issue was introduced by
4895c771c ("ipv4: Add FIB nexthop exceptions.")

The _XFER stack element size was set too small, 8 bytes, when it needs to be
16 bytes. As _XFER is the last stack element used by these implementations,
the 16 byte stores with 'movdqa' corrupt the stack where the value of register
%r12 is temporarily stored. As these implementations align the stack pointer
to 16 bytes, this corruption did not happen every time.
Patch corrects this issue.

This patch fixes a bug introduced in the v3.10 merge window.
The AB8500 External Regulator driver has recently landed upstream,
which registers each of the 3 external regulators located on the
AB8500. If these regulators are marked as 'always on', there is a
potential for power-loss. If they're not and are seemingly unused
the Regulator subsystem will attempt to disable them to save power.
This causes an issue for AUX1, AUX2 and AUX3 as they obtain their
power from EXT3. So we're specifying that here to prevent EXT3 from
being powered down.

Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces")
there's a bug in mac80211 when it unregisters with AP_VLAN interfaces
up. If the AP_VLAN interface was registered after the AP it belongs
to (which is the typical case) and then we get into this code path,
unregister_netdevice_many() will crash because it isn't prepared to
deal with interfaces being closed in the middle of it. Exactly this
happens though, because we iterate the list, find the AP master this
AP_VLAN belongs to and dev_close() the dependent VLANs. After this,
unregister_netdevice_many() won't pick up the fact that the AP_VLAN
is already down and will do it again, causing a crash.

A lot of code in mac80211 assumes that the hw queues are
set up correctly for all interfaces (except for monitor)
but this isn't true for AP_VLAN interfaces. Fix this by
copying the AP master configuration when an AP VLAN is
brought up, after this the AP interface can't change its
configuration any more and needs to be brought down to
change it, which also forces AP_VLAN interfaces down, so
just copying in open() is sufficient.

IPIs might be lost when a cpu gets brought offline:
When stop_machine executes its state machine there is a race window
for the state STOPMACHINE_DISABLE_IRQ where the to be brought offline
cpu might already have irqs disabled but a different cpu still may
have irqs enabled.
If the enabled cpu receives an interrupt and as a result sends an IPI
to the to be offlined cpu in its bottom halve context, the IPI won't
be noticed before the cpu is offline.
In fact the race window is much larger since there is no guarantee
when an IPI will be received.
To fix this check for enqueued but not yet received IPIs in the
cpu_disable() path and call the respective handlers before the cpu
is marked offline.

do_smart_update_queue() is called when an operation (semop,
semctl(SETVAL), semctl(SETALL), ...) modified the array. It must check
which of the sleeping tasks can proceed.
do_smart_update_queue() missed a few wakeups:
- if a sleeping complex op was completed, then all per-semaphore queues
must be scanned - not only those that were modified by *sops
- if a sleeping simple op proceeded, then the global queue must be
scanned again
And:
- the test for "|sops == NULL) before scanning the global queue is not
required: If the global queue is empty, then it doesn't need to be
scanned - regardless of the reason for calling do_smart_update_queue()
The patch is not optimized, i.e. even completing a wait-for-zero
operation causes a rescan. This is done to keep the patch as simple as
possible.

The eSDHC controller on the i.MX53 needs an additional, non spec
compliant CMD12 after a multiblock read with a predefined number of
blocks. Otherwise the internal state machine won't go back to the
idle state.
This commit effectively reverts 5b6b0ad6 (mmc: sdhci-esdhc-imx:
fix for mmc cards on i.MX5), which fixed part of the problem by
making multiblock reads work, however this fix was not sufficient
when multi- and singleblock reads got intermixed.
This implements the recommended workaround (Freescale i.MX Reference
Manual, section 29.6.8 "Multi-block Read") by manually sending a
CMD12 with the RSPTYP bits cleared.

Currently SDIO interrupts do not work on i.MX53 and maybe others.
This was observed with a Marvell 8787 based SDIO wifi adapter
using the mwifiex driver and firmware from the Marvell git
repository.
The symptom was a timeout after firmware download.
Observing the SDIO_DAT1 line showed that an interrupt was requested
(level 0) but no interrupt was generated in software, the line
stayed low until a timeout ocurred and the card was reset.
There is a Freescale errata
ENGcm11186 "eSDHC misses SDIO interrupt when CINT is disabled"
The workaround suggested by this errata is already implemented and
involves clearing and then setting the D3CD bit in the host control
register [see esdhc_writel_le()]
However, when esdhc_writeb_le() is later used to write to
SDHCI_HOST_CONTROL it always resets the D3CD bit.
To fix this simply add the D3CD bit to the set of bits
not modified by esdhc_writeb_le().

Daniel found a similar problem mentioned in
http://lkml.indiana.edu/hypermail/linux/kernel/1007.0/00961.html
And indeed this is the root cause : skb->cb[] contains data fooling IP
stack.
We must clear IPCB in ip_tunnel_xmit() sooner in case dst_link_failure()
is called. Or else skb->cb[] might contain garbage from GSO segmentation
layer.
A similar fix was tested on linux-3.9, but gre code was refactored in
linux-3.10. I'll send patches for stable kernels as well.
Many thanks to Daniel for providing reports, patches and testing !

gdbserver inserting a breakpoint ends up calling copy_user_page() for a
code page. The generic version of which (non-aliasing config) didn't set
the PG_arch_1 bit hence update_mmu_cache() didn't sync dcache/icache for
corresponding dynamic loader code page - causing garbade to be executed.
So now aliasing versions of copy_user_highpage()/clear_page() are made
default. There is no significant overhead since all of special alias
handling code is compiled out for non-aliasing build
