arm64: Survive invalid cpu enable-methods
Currently, if you pass the kernel a dtb where a cpu node has an
unsupported enable-method property (e.g. "not-psci"), it'll explode
horribly, as it iterates over the enable_ops array incorrectly. It
increments the pointer *at* the current element, rather than
incrementing the pointer *to* the current element. As the first two
elements pointed to structures that were contiguous in memory, this
happened to be equivalent. However the third element is NULL, so when
the list is exhausted, smp_get_enable_ops generates the wrong pointer,
and dereferences an arbitrary portion of memory, which currently happens
to contain zero.
This patch fixes this by indirecting the pointer one level, so we
iterate over the array elements correctly, avoiding the below panic:

ARM: 7702/1: Set the page table freeing ceiling to TASK_SIZE
ARM processors with LPAE enabled use 3 levels of page tables, with an
entry in the top level (pgd) covering 1GB of virtual space. Because of
the branch relocation limitations on ARM, the loadable modules are
mapped 16MB below PAGE_OFFSET, making the corresponding 1GB pgd shared
between kernel modules and user space.
If free_pgtables() is called with the default ceiling 0,
free_pgd_range() (and subsequently called functions) also frees the page
table shared between user space and kernel modules (which is normally
handled by the ARM-specific pgd_free() function). This patch changes
defines the ARM USER_PGTABLES_CEILING to TASK_SIZE when CONFIG_ARM_LPAE
is enabled.
Note that the pgd_free() function already checks the presence of the
shared pmd page allocated by pgd_alloc() and frees it, though with
ceiling 0 this wasn't necessary.

On architectures where a pgd entry may be shared between user and kernel

patch introduces a generic USER_PGTABLES_CEILING that arch code can
override. It is the responsibility of the arch code setting the ceiling

The Meta defconfigs set the log buffer size to just 8KiB, but with the

clockevents: Set dummy handler on CPU_DEAD shutdown
Vitaliy reported that a per cpu HPET timer interrupt crashes the
system during hibernation. What happens is that the per cpu HPET timer
gets shut down when the nonboot cpus are stopped. When the nonboot
cpus are onlined again the HPET code sets up the MSI interrupt which
fires before the clock event device is registered. The event handler
is still set to hrtimer_interrupt, which then crashes the machine due
to highres mode not being active.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=700333
There is no real good way to avoid that in the HPET code. The HPET
code alrady has a mechanism to detect spurious interrupts when event
handler == NULL for a similar reason.
We can handle that in the clockevent/tick layer and replace the
previous functional handler with a dummy handler like we do in
tick_setup_new_device().
The original clockevents code did this in clockevents_exchange_device(),
but that got removed by commit
7c1e76897 (clockevents: prevent
clockevent event_handler ending up handler_noop) which forgot to fix
it up in tick_shutdown(). Same issue with the broadcast device.

ACPI: video: correct acpi_video_bus_add error processing
acpi_video_bus_get_devices() may fail due to some video output device
doesn't have the _ADR method, and in this case, the error processing
is to simply free the video structure in acpi_video_bus_add(), while
leaving those already registered video output devices in the wild,
which means for some video output device, we have already registered
a backlight interface and installed a notification handler for it.
So it can happen when user is using this system, on hotkey pressing,
the notification handler will send a keycode through a non-existing
input device, causing kernel freeze.
To solve this problem, free all those already registered video output
devices once something goes wrong in acpi_video_bus_get_devices(), so
that no wild backlight interfaces and notification handlers exist.
