"Some ARM fixes, the biggest of which is the fix for the signal return
codes; this came up due to an interaction between the V7M nommu

Thumb-2 to work).
I've also fixed a number of breakages on footbridge platforms as I've
upgraded one of my machines to v3.12... one which had a 1200 day

Currently mx53 (CortexA8) running at 1GHz reports:
Calibrating delay loop... 663.55 BogoMIPS (lpj=3317760)
Tom Evans verified that alignments of 0x0 and 0x8 run the two instructions of __loop_delay in one clock cycle (1 clock/loop), while alignments of 0x4 and 0xc take 3 clocks to run the loop twice. (1.5 clock/loop)
The original object code looks like this:
00000010 <__loop_const_udelay>:
10: e3e01000 mvn r1, #0
14: e51f201c ldr r2, [pc, #-28] ; 0 <__loop_udelay-0x8>

40: 8afffffe bhi 3c <__loop_delay>

After adding the 'align 3' directive to __loop_delay (align to 8 bytes):
00000010 <__loop_const_udelay>:
10: e3e01000 mvn r1, #0
14: e51f201c ldr r2, [pc, #-28] ; 0 <__loop_udelay-0x8>

48: e1a0f00e mov pc, lr
4c: e320f000 nop {0}
, which now reports:
Calibrating delay loop... 996.14 BogoMIPS (lpj=4980736)
Some more test results:
On mx31 (ARM1136) running at 532 MHz, before the patch:
Calibrating delay loop... 351.43 BogoMIPS (lpj=1757184)
On mx31 (ARM1136) running at 532 MHz after the patch:
Calibrating delay loop... 528.79 BogoMIPS (lpj=2643968)
Also tested on mx6 (CortexA9) and on mx27 (ARM926), which shows the same
BogoMIPS value before and after this patch.

Copying a function with memcpy() and then trying to execute the
result isn't trivially portable to Thumb.
This patch modifies the kexec soft restart code to copy its
assembler trampoline relocate_new_kernel() using fncpy() instead,
so that relocate_new_kernel can be in the same ISA as the rest of
the kernel without problems.

After "ARM: signal: sigreturn_codes should be endian neutral to
work in BE8" commit, thumb only platforms, like armv7m, fails to
compile sigreturn_codes.S. The reason is that for such arch
values '.arm' directive and arm opcodes are not allowed.
Fix conditionally enables arm opcodes only if no CONFIG_CPU_THUMBONLY
defined and it uses .org instructions to keep sigreturn_codes
layout.

Commit f6f91b0d9fd9 (ARM: allow kuser helpers to be removed from the

code setting up the initial page tables was updated, the code which
allocates page tables for new processes wasn't, neither was the code
which tears down the mappings. Fix this.

This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.
The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:
* mcpm_cpu_power_down() must be pending for the CPU, so that we
don't get confused by false STANDBYWFI positives arising from
CPUidle. This is detected by waiting for the tc2_pm use count
for the target CPU to reach 0.
* Either the SPC must report that the CPU has asserted
STANDBYWFI, or the TC2 tile's reset control logic must be
holding the CPU in reset.
Just checking for STANDBYWFI is not sufficient, because this
signal is not latched when the the cluster is clamped off and
powered down: the relevant status bits just drop to zero. This
means that STANDBYWFI status cannot be used for reliable
detection of the last CPU in a cluster reaching WFI.
This patch is required in order for kexec to work with MCPM on TC2.
MCPM code was changed in commit 0de0d6467525 ('ARM: 7848/1: mcpm:
Implement cpu_kill() to synchronise on powerdown'), and since then it
will hit a WARN_ON_ONCE() due to power_down_finish not being implemented
on the TC2 platform.

This is due to use of the .arch_extension mp directive immediately prior

nothing if !CONFIG_SMP, gas will still choke on the directive.
This patch fixes the issue by only emitting the sequence (including the

Commit 26273e02a0cf (ARM: OMAP2+: Fix build for dra7xx without
omap4 and 5) attempted to fix randconfig found errors for
redefinition of omap44xx_prm_reconfigure_io_chain, but was
not enough.
We need to check for AM43XX without any omap4 or 5 related
SoCs as well. And looks like we have prm44xx.o built always
anyways with omap-4-5-prcm-common because of the calls to
omap4_prm_vp_clear_txdone, so we can remove the duplicate
entries in the Makefile.

The spdif "rxtx5" clock option is being set to ipg clk (62) by mistake.
This causes an incorrect time keeping when spdif driver is running,
because ipg is ancestor clock for clocksource while spdif driver will
change the rate of this clock in certain circumstance. Before the
correct clock for "rxtx5" option can be supplied, let's disable this
option for now by filling a dummy clock for it.

Using virt_to_phys on percpu mappings is horribly wrong as it may be
backed by vmalloc. Introduce kvm_kaddr_to_phys which translates both
types of valid kernel addresses to the corresponding physical address.
At the same time resolves a typing issue where we were storing the
physical address as a 32 bit unsigned long (on arm), truncating the
physical address for addresses above the 4GB limit. This caused
breakage on Keystone.

Looks like we're missing few entries for omap2 and the drivers
have only worked because of the omap hwmod building the devices
for the missing entries.
Let's fix the missing entries so we don't need to rely on hwmod
for the basic data and can then later on remove the duplicate
data from hwmod. Otherwise device tree only drivers will not
work properly.

Commit f2bf0e72d000 (ARM: OMAP2+: Add minimal 8250 support
for GPMC) added support for using bootloader timings for some
devices. Turns out we can do the same by looking at the compatible
flags of the child without adding a new function as smc91x has
a similar issue as 8250 with the bootloader timings.
And let's fix the 8250 naming, we should use the device type as
the name like uart instead of 8250 for zoom dts file.

OMAP device hooks around suspend|resume_noirq ensures that hwmod
devices are forced to idle using omap_device_idle/enable as part of
the last stage of suspend activity.
For a device such as i2c who uses autosuspend, it is possible to enter
the suspend path with dev->power.runtime_status = RPM_ACTIVE.
As part of the suspend flow, the generic runtime logic would increment
it's dev->power.disable_depth to 1. This should prevent further
pm_runtime_get_sync from succeeding once the runtime_status has been
set to RPM_SUSPENDED.
Now, as part of the suspend_noirq handler in omap_device, we force the
following: if the device status is !suspended, we force the device
to idle using omap_device_idle (clocks are cut etc..). This ensures
that from a hardware perspective, the device is "suspended". However,
runtime_status is left to be active.
*if* an operation is attempted after this point to
pm_runtime_get_sync, runtime framework depends on runtime_status to
indicate accurately the device status, and since it sees it to be
ACTIVE, it assumes the module is functional and returns a non-error
value. As a result the user will see pm_runtime_get succeed, however a
register access will crash due to the lack of clocks.
To prevent this from happening, we should ensure that runtime_status
exactly indicates the device status. As a result of this change
any further calls to pm_runtime_get* would return -EACCES (since
disable_depth is 1). On resume, we restore the clocks and runtime
status exactly as we suspended with. These operations are not expected
to fail as we update the states after the core runtime framework has
suspended itself and restore before the core runtime framework has
resumed.
