are non-integral to the framebuffer dimensions.

ARM: VFP: fix emulation of second VFP instruction

Martin Storsjö reports that the sequence:

	ee312ac1	vsub.f32	s4, s3, s2
	ee702ac0	vsub.f32	s5, s1, s0
	e59f0028	ldr		r0, [pc, #40]
	ee111a90	vmov		r1, s3

on Raspberry Pi (implementor 41 architecture 1 part 20 variant b rev 5)
where s3 is a denormal and s2 is zero results in incorrect behaviour -
the instruction "vsub.f32 s5, s1, s0" is not executed:

	VFP: bounce: trigger ee111a90 fpexc d0000780
	VFP: emulate: INST=0xee312ac1 SCR=0x00000000
	...

As we can see, the instruction triggering the exception is the "vmov"
instruction, and we emulate the "vsub.f32 s4, s3, s2" but fail to
properly take account of the FPEXC_FP2V flag in FPEXC.  This is because
the test for the second instruction register being valid is bogus, and
will always skip emulation of the second instruction.

ARM: 7492/1: add strstr declaration for decompressors

With the generic unaligned.h, more kernel headers get pulled in including
dynamic_debug.h which needs strstr. As it is not really used, we only need
a declaration here.

ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up()

Cleanup and preparation for the next change.

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.

wake_up_process() should be never used to wakeup a TASK_STOPPED/TRACED task

wake_up_process() should never wakeup a TASK_STOPPED/TRACED task.
Change it to use TASK_NORMAL and add the WARN_ON().

TASK_ALL has no other users, probably can be killed.
