Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

Since the implementation of cmpxchg64() uses instructions that are not
Thumb instructions, only define cmpxchg64() if not building in Thumb

Use __GFP_ZONE_MOVABLE to replace (__GFP_HIGHMEM | __GFP_MOVABLE).
___GFP_DMA, ___GFP_HIGHMEM and ___GFP_DMA32 have been deleted from GFP
bitmasks, the bottom three bits of GFP mask is reserved for storing
encoded zone number.
__GFP_ZONE_MOVABLE contains encoded ZONE_MOVABLE and __GFP_MOVABLE fl

Hmmm, endless loop in find_rr_leaf or similar?
Introduce the family of LED devices that can
drive a torch, strobe or IR LED.
The LED driver can be configured with a strobe
timer to execute a strobe flash. The IR LED
brightness is controlled via the torch brightness
register.
The data sheet for each the LM36010 and LM36011
LED drivers can be
Introduce the device tree bindings for the lm3601x
family of LED torch, flash and IR drivers.

Use new return type vm_fault_t for fault handler. For now,
this is just documenting that the function returns a
VM_FAULT value rather than an errno. Once all instances are
converted, vm_fault_t will become a distinct type.

This parameter has been around since commit e162b39a368f ("softlockup:
decouple hung tasks check from softlockup detection") in 2009 but was

This only probes on arm64 so far, but hopefully that driver will be
generalized soon.
