The CMA support marked as the experimental in the kernel Kconfig.
After turns it on, we found many memory issues. Since this CMA
support on the 3.5.7 kernel is not mature enough, just turn it
off and use back the consistent remap DMA.

commit 5e4ba617c1b584b2e376f31a63bd4e734109318a upstream.
Martin Storsjö reports that the sequence:
ee312ac1 vsub.f32 s4, s3, s2
ee702ac0 vsub.f32 s5, s1, s0
e59f0028 ldr r0, [pc, #40]
ee111a90 vmov r1, s3
on Raspberry Pi (implementor 41 architecture 1 part 20 variant b rev 5)
where s3 is a denormal and s2 is zero results in incorrect behaviour -
the instruction "vsub.f32 s5, s1, s0" is not executed:
VFP: bounce: trigger ee111a90 fpexc d0000780
VFP: emulate: INST=0xee312ac1 SCR=0x00000000
...
As we can see, the instruction triggering the exception is the "vmov"
instruction, and we emulate the "vsub.f32 s4, s3, s2" but fail to
properly take account of the FPEXC_FP2V flag in FPEXC. This is because
the test for the second instruction register being valid is bogus, and
will always skip emulation of the second instruction.

CONFIG_VFPv3 set
commit 39141ddfb63a664f26d3f42f64ee386e879b492c upstream.
After commit 846a136881b8f73c1f74250bf6acfaa309cab1f2 ("ARM: vfp: fix
saving d16-d31 vfp registers on v6+ kernels"), the OMAP 2430SDP board
started crashing during boot with omap2plus_defconfig:
[ 3.875122] mmcblk0: mmc0:e624 SD04G 3.69 GiB
[ 3.915954] mmcblk0: p1
[ 4.086639] Internal error: Oops - undefined instruction: 0 [#1] SMP ARM
[ 4.093719] Modules linked in:
[ 4.096954] CPU: 0 Not tainted (3.6.0-02232-g759e00b #570)
[ 4.103149] PC is at vfp_reload_hw+0x1c/0x44
[ 4.107666] LR is at __und_usr_fault_32+0x0/0x8
It turns out that the context save/restore fix unmasked a latent bug
in commit 5aaf254409f8d58229107b59507a8235b715a960 ("ARM: 6203/1: Make
VFPv3 usable on ARMv6"). When CONFIG_VFPv3 is set, but the kernel is
booted on a pre-VFPv3 core, the code attempts to save and restore the
d16-d31 VFP registers. These are only present on non-D16 VFPv3+, so
this results in an undefined instruction exception. The code didn't
crash before commit 846a136 because the save and restore code was
only touching d0-d15, present on all VFP.
Fix by implementing a request from Russell King to add a new HWCAP
flag that affirmatively indicates the presence of the d16-d31
registers:
http://marc.info/?l=linux-arm-kernel&m=135013547905283&w=2
and some feedback from Måns to clarify the name of the HWCAP flag.

commit 846a136881b8f73c1f74250bf6acfaa309cab1f2 upstream.
Michael Olbrich reported that his test program fails when built with
-O2 -mcpu=cortex-a8 -mfpu=neon, and a kernel which supports v6 and v7
CPUs:
volatile int x = 2;
volatile int64_t y = 2;
int main() {
volatile int a = 0;
volatile int64_t b = 0;
while (1) {
a = (a + x) % (1 << 30);
b = (b + y) % (1 << 30);
assert(a == b);
}
}
and two instances are run. When built for just v7 CPUs, this program
works fine. It uses the "vadd.i64 d19, d18, d16" VFP instruction.
It appears that we do not save the high-16 double VFP registers across
context switches when the kernel is built for v6 CPUs. Fix that.

The patch of "ENGR00264855 backlight: Support backlight shared by
multiple fbs" doesn't consider that bd->props.fb_blank could be
shared by several framebuffers which use the same backlight device.
This causes the pwm backlight wrongly check the fb blank status.
This patch corrects the setting for the fb blank status by
considering all the framebuffers in question to fix the issue.

In August 2012, Matthew Gretton-Dann checked a change into binutils
labelled "Error on obsolete & warn on deprecated registers", apparently as
part of ARMv8 support. Apparently, this was supposed to emit the message
"Warning: This coprocessor register access is deprecated in ARMv8" when
using certain mcr/mrc instructions and building for ARMv8. Unfortunately,
the message that is actually emitted appears to be '(null)', which is
less helpful in comparison.
Even more unfortunately, this is biting us on every single kernel
build with a new gas, because arch/arm/boot/compressed/head.S and some
other files in that directory are built with -march=all since kernel
commit 80cec14a8 "[ARM] Add -march=all to assembly file build in
arch/arm/boot/compressed" back in v2.6.28.
This patch reverts Russell's nice solution and instead marks the head.S
file to be built for armv7-a, which fortunately lets us build all
instructions in that file without warnings even on the broken binutils.
Without this patch, building anything results in:
arch/arm/boot/compressed/head.S: Assembler messages:
arch/arm/boot/compressed/head.S:565: Warning: (null)

If system run higher cpu loading with bigger current, such as GPU or VPU,
the voltage of battery will decrease down quickly and rise up later.But the
battery driver only permit voltage decreasing while discharging before, in
other words, in the above case , the voltage will keep in very low level,
although the voltage will rise back again.
Now, remove the constrain in the code. Of course, with the patch, voltage will
down and rise back when run high loading user case, but it's better than
LOW ALWAYS, in worst case, the battery capacity will be 0 as test team reported
Please note :
Current battery capaity is not accurate because of hardware
design defect(ENGR00219632) on Sabresd.So please ignore the accuracy issue.

We currently call cancel_work_sync() to have all left work be done. But,
this is not safe to make sure all left work being done successfully.
Instead, chances are that some work may be cancelled before starting
to be done, which may cause frame lost and make us hang at upcoming
wait_event_interruptible() in videobuf_waiton() called from video buffer
core v1 framework's dqbuf API. This patch replaces the function
