02d6e63307 arm/mach-keystone: remove legacy __cpuinit sections that crept in
We removed __cpuinit support (leaving no-op stubs) quite some time
ago.  However two crept back in as of commit 5eb3da7246a5b2dfac9f38
("ARM: keystone: Switch over to coherent memory address space")

Since we want to clobber the stubs too, get these removed now.

9ce93bdda7 ARM: fix new BSYM() usage introduced via for-arm-soc branch
Commit 32e55a777f83 ("ARM: 8389/1: Add cpu_resume_arm() for firmwares
that resume in ARM state") needed to introduce a new usage of BSYM()
to fix a problem with a previous patch.  This in turn causes a conflict
with the "bsym" branch which removes this symbol, replacing it with a
'badr' assembly macro.  Fix this up.

970d96f9a8 ARM: 8383/1: nommu: avoid deprecated source register on mov
In Thumb2 mode, the stack register r13 is deprecated if the
destination register is the program counter (r15). Similar to
head.S, head-nommu.S uses r13 to store the return address used
after configuring the CPU's CP15 register. However, since we do
not enable a MMU, there will be no address switch and it is
possible to use branch with link instruction to call
__after_proc_init.

Avoid using r13 completely by using bl to call __after_proc_init
and get rid of __secondary_switched.

Beside removing unnecessary complexity, this also fixes a
compiler warning when compiling a !MMU kernel:
Warning: Use of r13 as a source register is deprecated when r15
is the destination register.

32e55a777f ARM: 8389/1: Add cpu_resume_arm() for firmwares that resume in ARM state
Some platforms always enter the kernel in the ARM state even if
the kernel is compiled for THUMB2. Add a small wrapper on top of
cpu_resume() that switches into THUMB2 state.

This provides the functionality to fix a problem reported by Kevin
Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2
kernel because the platform's firmware always enters the kernel in
ARM mode from deep idle states.

(rmk: tweaked to work without BSYM->badr changes.)

8a14849b4a arm64: KVM: Switch vgic save/restore to alternative_insn
So far, we configured the world-switch by having a small array
of pointers to the save and restore functions, depending on the
GIC used on the platform.

Loading these values each time is a bit silly (they never change),
and it makes sense to rely on the instruction patching instead.

This leads to a nice cleanup of the code.

2879e43f09 Omap hwmod changes for v4.2 via Paul Walmsley <paul@pwsan.com>:
Several OMAP2+ hwmod changes for v4.2.  One patch cleans up a nasty
 interaction between the OMAP GPMC and the hwmod code when debugging is
 enabled.  IP block integration data has been added for the AM43xx EMIF
 RAM controller.  There's also a fix for the omap-aes driver when used in
 QEMU.  And finally, some changes to the OMAP3 hwmod code to support the
 use of the security IP blocks (AES and SHA) on GP devices, or when they've
 specifically been enabled in the DT data.
 
 Basic build, boot, and power management test results are here:

44fd8c7d40 ARM: socfpga: support suspend to ram
Add code that requests that the sdr controller go into
self-refresh mode.  This code is run from ocram.

Suspend-to-RAM and EDAC support are mutually exclusive on
SOCFPGA.  If the EDAC is enabled, it will prevent the
platform from going into suspend.

Example of how to request to suspend to ram:
 $ echo enabled > \
/sys/devices/soc/ffc02000.serial0/tty/ttyS0/power/wakeup

 $ echo -n mem > /sys/power/state
