In command mode panel like JDI, there would be messy screen

2. Framebuffer comes out at first msm_fb_commit_wq_handler()
-> mdp4_overlay_commit() after resume.
We should delay backlight to after framebuffer comes out.
3. Add set_recovery_backlight for the backlight in recovery mode.

KGSL_GPUMEM_ALLOC_ID now takes a flag,
KGSL_MEMFLAGS_USE_CPU_MAP. When set, the GPU
mapping will be set up to match the CPU mapping
during mmap(). This feature is only supported when
using per process pagetables with the IOMMU. The
flags field of KGSL_GPUMEM_ALLOC_ID is copied back
to userspace and KGSL_MEMFLAGS_USE_CPU_MAP will
be cleared when this feature is not supported.
The IOMMU virtual address space has been adjusted
when perprocess pagetables is enabled so that the
entire userpace address range (0 to TASK_SIZE) can
have equivalent mappings on the IOMMU. For buffers
that do not have equivalent mappings, the address
range from PAGE_OFFSET to KGSL_IOMMU_GLOBAL_MEM_BASE
is used.

Previously, the gpu address has been used to uniquely
identify each memory allocation. Upcoming patches will
introduce cases where an allocation does not always
have a gpu address, so an additional id is needed.
IOCTL_KGSL_GPUMEM_ALLOC_ID allocates pages and returns
an id.
IOCTL_KGSL_GPUMEM_FREE_ID frees an id. KGSL_SHAREDMEM_FREE
can still be used to free by GPU address, if it exists.
The id can also be passed to mmap(), shifted left by
PAGE_SIZE to get a CPU mapping for the buffer.
IOCTL_KGSL_GPUMEM_ALLOC_GET_INFO can be called to retrieve
the id and other information about the buffer.

The v1 iommu only supports splitting between TTBR0 and TTBR1
on a power of two boundary. Cutting off the userspace address
at 2G (0x80000000) is inconvienient, as the GPU userspace
address space should align with the CPU address space.
This requires changing how global allocations are managed,
since there is no longer a separate pagetable for TTBR1.
The default pagetable is still the master of these allocations
and maintains the gen_pool for allocating global addresses.
But now, these regions are mapped into each process pagetable
by calling kgsl_setup_pt(). This requires kgsl_mmu_map
and kgsl_mmu_unmap to be able to handle mapping without
virtual address allocation.

controlling what process can become the binder context manager
(binder_set_context_mgr), controlling the ability of a process
to invoke a binder transaction/IPC to another process (binder_transaction),
controlling the ability a process to transfer a binder reference to

putreg() assumes that the tracee is not running and pt_regs_access() can
safely play with its stack. However a killed tracee can return from
ptrace_stop() to the low-level asm code and do RESTORE_REST, this means
that debugger can actually read/modify the kernel stack until the tracee
does SAVE_REST again.
set_task_blockstep() can race with SIGKILL too and in some sense this
race is even worse, the very fact the tracee can be woken up breaks the
logic.
As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace()
call, this ensures that nobody can ever wakeup the tracee while the
debugger looks at it. Not only this fixes the mentioned problems, we
can do some cleanups/simplifications in arch_ptrace() paths.
Probably ptrace_unfreeze_traced() needs more callers, for example it
makes sense to make the tracee killable for oom-killer before
access_process_vm().
While at it, add the comment into may_ptrace_stop() to explain why
ptrace_stop() still can't rely on SIGKILL and signal_pending_state().

signal_wake_up(resume => true) is overused. None of ptrace/jctl callers
actually want to wakeup a TASK_WAKEKILL task, but they can't specify the
necessary mask.
Turn signal_wake_up() into signal_wake_up_state(state), reintroduce
signal_wake_up() as a trivial helper, and add ptrace_signal_wake_up()
which adds __TASK_TRACED.
This way ptrace_signal_wake_up() can work "inside" ptrace_request()
even if the tracee doesn't have the TASK_WAKEKILL bit set.
