This is a driver for the Integrated Silicon Solution Inc. LED driver
chips series IS31FL319x. They can drive 1, 3, 6 or up to 9
LEDs.
Each LED is individually controllable in brightness (through pwm)
in 256 steps so that RGB LEDs can show any of ca. 16 Mio colors.
The maximum current of the LEDs can be programmed and limited to
5 .. 40mA through a device tree property.
The chip is connected through I2C and can have one of 4 addresses
in the range 0x64 .. 0x67 depending on how the AD pin is connected. The
address is defined by the reg property as usual.
The chip also has a shutdown input which could be connected to a GPIO,
but this driver uses software shutdown if all LEDs are inactivated.
The chip also has breathing and audio features which are not fully
supported by this driver.
Tested-on: OMAP5 based Pyra handheld prototype.

Both the fence and event alloc are safe to be done without holding the GPU
lock, as they either don't need any locking (fences) or are protected by
their own lock (events).
This solves a bad locking interaction between the submit path and the
recover worker. If userspace manages to exhaust all available events while
the GPU is hung, the submit will wait for events to become available
holding the GPU lock. The recover worker waits for this lock to become
available before trying to recover the GPU which frees up the allocated
events. Essentially both paths are deadlocked until the submit path
times out waiting for available events, failing the submit that could
otherwise be handled just fine if the recover worker had the chance to
bring the GPU back in a working state.

Since contexts are not currently shared between userspace processes, we
have an exact correspondence between context creator and guilty batch

Treat the VMA as the primary struct responsible for tracking bindings
into the GPU's VM. That is we want to treat the VMA returned after we
pin an object into the VM as the cookie we hold and eventually release

and then searching for the relevant pin later.

Use the GGTT VMA as the primary cookie for handing ring objects as
the most common action upon the ring is mapping and unmapping which act
upon the VMA itself. By restructuring the code to work with the ring
VMA, we can shrink the code and remove a few cycles from context pinning.
v2: Move the flush of the object back to before the first pin. We use
the am-I-bound? query to only have to check the flush on the first
bind and so avoid stalling on active rings.

i915_vma_pin_iomap() is short-lived and the pinning demarcates the

No longer is knowing how much of the GTT (both mappable aperture and
beyond) relevant, and the output clutters the real information - that is
how many objects are allocated and bound (and by who) so that we can
quickly grasp if there is a leak.
v2: Relent, and rename pinned to indicate display only. Since the
display objects are semi-static and are of variable size, they are the
interesting objects to watch over time for aperture leaking. The other
pins are either static (such as the scratch page) or very short lived
(such as execbuf) and not part of the precious GGTT.

The ACPI MADT has a 32-bit field providing lapic address at which
each processor can access its lapic information. MADT also contains
an optional entry to provide a 64-bit address to override the 32-bit
one. However the current code does the lapic address override entry
parsing twice. One is in early_acpi_boot_init() because AMD NUMA need
get boot_cpu_id earlier. The other is in acpi_boot_init() which parses
all MADT entries.
So in this patch we remove the repeated code in the 2nd part.
Meanwhile print lapic override entry information like other MADT entry,
this will be added to boot log.
This patch is not supposed to change any runtime behavior, other than
improving kernel messages.

Previously early_acpi_boot_init() was called in early_get_boot_cpu_id()
to get the value for boot_cpu_physical_apicid. Now early_acpi_boot_init()
has been taken out and moved to setup_arch(), the name of
early_get_boot_cpu_id() doesn't match its implementation anymore, and
only the getting boot-time SMP configuration code was left.
So in this patch we open code it.
Also move the smp_found_config check into default_get_smp_config to
simplify code, because both early_get_smp_config() and get_smp_config()
call x86_init.mpparse.get_smp_config().
Also remove the redundent CONFIG_X86_MPPARSE #ifdef check when we call
