ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression)
After commit
e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).
However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a

be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.

drm: do not sleep on vblank while holding a mutex
drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.
v2: incorporate comments received from Daniel Vetter and
Michel Daenzer.
v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
that the only thing not yet protected with locks and atomic
ops is the write to dev->last_vblank_wait. It's only used in a
debug file in proc, and the current code already employs no
correct locking: the proc file only takes dev->struct_mutex,
whereas drm_wait_vblank implicitly took the drm_global_mutex.
Given all this, it's not worth bothering to try to fix
the locks at this time.

drm/radeon: Make sure CS mutex is held across GPU reset.
This was only the case if the GPU reset was triggered from the CS ioctl,
otherwise other processes could happily enter the CS ioctl and wreak havoc
during the GPU reset.
This is a little complicated because the GPU reset can be triggered from the
CS ioctl, in which case we're already holding the mutex, or from other call
paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't
allow recursive locking or finding out the mutex owner, so we need to handle
this with helper functions which allow recursive locking from the same
process.

However, this would still give many regressions on machines with broken
BIOS. They set this bit wrongly even on active pins.

Btrfs: rework error handling in btrfs_mount()
Commits
6c41761f and
45ea6095 introduced the possibility of NULL pointer
dereference on error paths, also we would leave all devices busy and
leak fs_info with all sub-structures on error when trying to mount an
already mounted fs to a different directory.
Fix this by doing all allocations before trying to open any of the
devices, adjust error path for mount-already-mounted-fs case.

Btrfs: avoid null dereference and leaks when bailing from open_ctree()
Fix bugs introduced by
6c41761f. Firstly, after failing to allocate any
of the tree roots (first 'goto fail' in open_ctree()) we would
dereference a NULL fs_info pointer in free_fs_info(). Secondly, after
failures from init_srcu_struct(), setup_bdi() and new_inode() we would
leak all earlier allocated roots: fs_info fields haven't been
initialized yet so free_fs_info() is rendered useless.
Fix this by initializing fs_info pointer and fs_info fields before any
allocations happen.

arm/tegra: Don't create duplicate gpio and pinmux devices
*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.
*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.
To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.
Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.
This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:
a) Initializing the HW state from DT nodes during GPIO and pinmux device
probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
their probe until after the gpio and pinmux drivers have probed.
v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.
