Subject: [PATCH 08/65] ARM: pxa: Use gpio arrays in palmld_hdd driver
Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.
This patch also properly frees GPIOs in case ata_host_activate() call fails.

Subject: [PATCH 11/65] ARM: pxa: clean up set_pxa_fb_info
set_pxa_fb_info() has been a long-standing wart in the naming scheme
of the pxa_set_xxx_info() functions. This renames the function, and
combines set_pxa_fb_parent() with set_pxa_fb_info().

Subject: [PATCH 16/65] ARM: pxa25x_udc: stop handling gpio-vbus internally
Stop handling gpio-vbus internally. All boards that depended on this
functionality have been converted to use gpio-vbus tranceiver. All
new boards can use it right from the start. Drop unused code.

Subject: [PATCH 18/65] ARM: pxafb: rework pxafb overlay memory management
PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
in memory allocation failure after ~1h of uptime (system does not have
115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
allocated.
Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.
This patch attempts to fix those issues.
Patch is based on Russell King's work.

Subject: [PATCH 21/65] ARM: pxafb: don't disable controller on cpufreq
transition if overlay in use
It's not safe to disable controller if overlay(s) is enabled (results in
system hang). So we avoid to disable controller in this case. Userspace
should choose proper governor to avoid freq changing when overlay is in
use, otherwise LCD may blink.

MIME-Version: 1.0

Current code inside babbage_fec_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value to the same level right after. This is not needed.
By using gpio_request_one it is possible to set the direction and initial value in one shot.

meaningful
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As there is a mx53_smd board in the kernel, using SMD_FEC_PHY_RST as the pin name can be misleading when used
on a MX53_EVK board.
Change the pin name to reflect the board name.

Subject: [PATCH 47/65] ARM: mx51_efika: update platform data for new mfd
changes
Note that this relies on stuff currently in mfd's next tree, but this
is also a newer driver. I'm not sure which tree it should go through,
as it's a problem that shows up in next.
From: Andres Salomon <dilinger@queued.net>
MFD changes in c738892f cause the mc13xxx_platform_data struct
to change. This changes one more (new) user of it, fixing a build
error.

Subject: [PATCH 58/65] ARM: 6833/1: perf: add required isbs() to ARMv7 backend
The ARMv7 architecture does not guarantee that effects from co-processor
writes are immediately visible to following instructions.
This patch adds two isbs to the ARMv7 perf code:
(1) Immediately after selecting an event register, so that the PMU state
following this instruction is consistent with the new event.
(2) Immediately before writing to the PMCR, so that any previous writes
to the PMU have taken effect before (typically) enabling the
counters.

Subject: [PATCH 59/65] ARM: 6834/1: perf: reset counters on all CPUs during
initialisation
ARMv7 dictates that the interrupt-enable and count-enable registers for
each PMU counter are UNKNOWN following core reset.
This patch adds a new (optional) function pointer to struct arm_pmu for
resetting the PMU state during init. The reset function is called on
each CPU via an arch_initcall in the generic ARM perf_event code and
allows the PMU backend to write sane values to any UNKNOWN registers.

Subject: [PATCH 60/65] ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency
If a counter overflows during a perf stat profiling run it may overtake
the last known value of the counter:
0 prev new 0xffffffff
|----------|-------|----------------------|
In this case, the number of events that have occurred is
(0xffffffff - prev) + new. Unfortunately, the event update code will
not realise an overflow has occurred and will instead report the event
delta as (new - prev) which may be considerably smaller than the real
count.
This patch adds an extra argument to armpmu_event_update which indicates
whether or not an overflow has occurred. If an overflow has occurred
then we use the maximum period of the counter to calculate the elapsed
events.

Subject: [PATCH 62/65] ARM: 6836/1: kprobes/fix emulation of LDR/STR
instruction when Rn == PC
The Rn value from the emulation is unconditionally written back;
this is fine as long as Rn != PC because in that case, even if the
instruction isn't a write back instruction, it will only result in the
same value being written back.
In case Rn == PC, then the emulated instruction doesn't have the
actual PC value in Rn but an adjusted value; when this is written
back, it will result in the PC being incorrectly updated.
An altenative solution would be to check bits 24 and 22 to see whether
the instruction actually is a write back instruction or not. I think
it's enough to check whether Rn != PC, because:
- it's looks cheaper than the alternative
- to my understaning it's not permitted to update the PC with a write
back instruction, so we don't lose any ability to emulate legal
instructions.
- in case of writing back for non write back instructions where Rn != PC, it doesn't matter because the values are the same.
Regarding the second point above, it would possibly be prudent to add
some checking to prep_emulate_ldr_str(), so that instructions with
both write back and Rn == PC would be rejected.

Subject: [PATCH 65/65] ARM: 6826/1: Merge v6 and v7 DEBUG_LL DCC support
The inline assembly differences for v6 vs. v7 are purely
optimizations. On a v7 processor, an mrc with the pc sets the
condition codes to the 28-31 bits of the register being read. It
just so happens that the TX/RX full bits the DCC support code is
testing for are high enough in the register to be put into the
condition codes. On a v6 processor, this "feature" isn't
implemented and thus we have to do the usual read, mask, test
operations to check for TX/RX full. Thus, we can drop the v7
implementation and just use the v6 implementation for both.
