This reverts commit 41bd956de3dfdc3a43708fe2e0c8096c69064a1e.
The fix is incorrect and not appropiate for the latest kernels.
In fact it _causes_ the BUG: scheduling while atomic while
doing vCPU hotplug.

is also set back to WAIT_CLOCKED from STOP_POWER_OFF.

It's buggy to disable the cpu that is being hot-unplugged in .cpu_die
hook which runs on the cpu itself. Instead, it should be done in
.cpu_kill which runs on the thread (another cpu) that asks for shutting
down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill
hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die,
so that we can get a more stable cpu hot-plug operation.

__hyp_stub_install duplicates quite a bit of safe_svcmode_maskall
by forcing the CPU back to SVC. This is unnecessary, as
safe_svcmode_maskall is called just after.
Furthermore, the way we build SPSR_hyp is buggy as we fail to mask
the interrupts, leading to interesting behaviours on TC2 + UEFI.
The fix is to simply remove this code and rely on safe_svcmode_maskall
to do the right thing.

This patch is brought to you by the letter 'H'.
Commit 20b279 breaks compatiblity with older perf binaries when run with
precise modifier (:p or :pp) by requiring the exclude_guest attribute to be
set. Older binaries default exclude_guest to 0 (ie., wanting guest-based
samples) unless host only profiling is requested (:H modifier). The workaround
for older binaries is to add H to the modifier list (e.g., -e cycles:ppH -
toggles exclude_guest to 1). This was deemed unacceptable by Linus:
https://lkml.org/lkml/2012/12/12/570
Between family in town and the fresh snow in Breckenridge there is no time left
to be working on the proper fix for this over the holidays. In the New Year I
have more pressing problems to resolve -- like some memory leaks in perf which
are proving to be elusive -- although the aforementioned snow is probably why
they are proving to be elusive. Either way I do not have any spare time to work
on this and from the time I have managed to spend on it the solution is more
difficult than just moving to a new exclude_guest flag (does not work) or
flipping the logic to include_guest (which is not as trivial as one would
think).
So, two options: silently force exclude_guest on as suggested by Gleb which
means no impact to older perf binaries or revert the original patch which
caused the breakage.
This patch does the latter -- reverts the original patch that introduced the
regression. The problem can be revisited in the future as time allows.

This is mostly a port of dbf62d50067e ("ARM: mm: introduce L_PTE_VALID
for page table entries") and 26ffd0d43b18 ("ARM: mm: introduce present,
faulting entries for PAGE_NONE") from ARM, which makes use of present,
faulting page table entries for page table entries mapped as PROT_NONE.
The main difference with this implementation is that we can make use of
the two pte type bits in order to avoid allocating a software bit for
identifying PROT_NONE pages, instead reserving the 10b suffix for these
types of mappings.
This is required to prevent users from accessing such pages via syscalls
such as read/write over a pipe.

Marking non-present ptes as read-only can corrupt file ptes, breaking
things like swap and file mappings.
This patch ensures that we only manipulate user pte bits when the pte
is marked present.

This patch is an arm64 version of ce73ec6db47a ("powerpc/vdso: Remove
redundant locking in update_vsyscall_tz()").
Timezone data is not protected, so the sequence counter is not required
to ensure consistency. Furthermore, having multiple paths updating the
counter leads to a race between update_vsyscall and update_vsyscall_tz,
so remove the timezone sequence counting from both the kernel and the
vdso.

Note that the pinctrl conversion also fixes GPIO support for ns2 boards.
Since commit f9e75922: "ARM: Kirkwood: Make use of mvebu pincltl and
gpio", the mvbu_gpio driver is used for DT boards. As mvbu_gpio relies
on the pinctrl driver, then a pinctrl definition must be given to allow
the GPIO configuration.

Retract back most macro definitions which went into the
user-visible mce.h header. Even though those bits are mostly
hardware-defined/-architectural, their naming is not. If we export them
to userspace, any kernel unification/renaming/cleanup cannot be done
anymore since those are effectively cast in stone. Besides, if userspace
wants those definitions, they can write their own defines and go crazy.

People are back from the holiday breaks, and it shows. Here are a bunch of
fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups,
a few __init annotation fixes and some error handling improvement
in their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to see
here, mostly from the OMAP PM changes, but nothing overly crazy.
