Currently we blindly use the value of cmd_per_lun as the initial setting for
queue_depth. This fails miserably (hangs the system) if it is zero, which is
the default value for anything uninitialised in the template. The net result
is that every host template has to set a value for cmd_per_lun. Instead, use
a default value of 1 if the actual value is unset. This should pave the way
for removing cmd_per_lun from all the templates and eventually from SCSI
itself.

Hardware planes are driven by the timing generator of the CRTC they are
associated to. Changing the association requires restarting the CRTC
group that the plane belongs to, resulting in flicker on the other CRTC.
To avoid flicker as much as possible, try to allocate planes first from
the free planes already associated with the target CRTC. If allocation
fails then fall back to allocation from all free planes.

The copy_xregs_to_kernel*() and copy_kernel_to_xregs*() functions are used
to copy FPU registers to kernel memory and vice versa.
They are never expected to fail, yet they have a return code, mostly because
that way they can share the assembly macros with the copy*user*() functions.
This error code is then silently ignored by the context switching
and other code - which made the bug in:
b8c1b8ea7b ("x86/fpu: Fix FPU state save area alignment bug")
harder to fix than necessary.
So remove the return values and check for no faults when FPU debugging
is enabled in the .config.
This improves the eagerfpu context switching fast path by a couple of
instructions, when FPU debugging is disabled:

There's a confusing aspect of how xstate_fault() constraints are
handled by the FPU register/memory copying functions in
fpu/internal.h: they use "0" (0) to signal that the asm code
will not always set 'err' to a valid value.
But 'err' is already initialized to 0 in C code, which is duplicated
by the asm() constraint. Should the initialization value ever be
changed, it might become subtly inconsistent with the not too clear
asm() constraint.
Use 'err' as the value of the input variable instead, to clarify
this all.

There are two problems with xstate_fault handling:
- The xstate_fault() macro takes an argument, but that's
propagated into the assembly named label as well. This
is technically correct currently but might result in
failures if anytime a more complex argument is used.
So use a separate '_err' name instead for the label.
- All the xstate_fault() using functions have an error
variable named 'err', which is an output variable to
the asm() they are using. The problem is, it's not always
set by the asm(), in which case the compiler might
optimize out its initialization, so that the C variable
'err' might become corrupted after the asm() - confusing
anyone who tries to take advantage of this variable
after the asm(). Mark it an input variable as well.
This is a latent bug currently, but an upcoming debug
patch will make use of 'err'.

So the xstate code was probably first copied from the fxregs code,
hence it carried over the 'fx' naming for the state pointer variable.
But this is slightly confusing, as we usually on call the (legacy)
MMX/SSE state 'fx', both in data structures and in the functions
build around FXSAVE/FXRSTOR.
So rename it to 'xstate' to make it more apparent what it is related to.

The cryptoff parameter was added to facilitate the skipping of
IVs that sit between the AD and the plain/cipher text. However,
it was never implemented correctly as and we do not handle users
such as IPsec setting cryptoff. It is simply ignored.
Implementing correctly is in fact more trouble than what it's
worth.
This patch removes the uses of cryptoff by moving the AD forward
to fill the gap left by the IV. The AD is moved back after the
underlying AEAD processing is finished.
This is in fact beter than the cryptoff solution because it allows
algorithms that use seqniv (i.e., GCM and CCM) to hash the whole
packet as a single piece, while cryptoff meant that there was
guaranteed to be a gap.
