Hello Andrew,
could you, please, propagate the patch in
https://lkml.org/lkml/2015/3/29/189
to the MM tree.
It is independent of the other two patches in the patch series.
Rework for the other patches was requested by Alexey Dobriyan in
https://lkml.org/lkml/2015/3/31/251
Best regards
Heinrich

Hi Daniel,
I'd very much like to see us converge on a solution for this soon. The
existing hack is getting in the way of other rework of the arm/arm64
perf code.
I think the approach this patch takes should work, but there are some
parts that can be cleaned up (hopefully mostly cosmetic). Unfortu

The patch introduces a helper that gives a divider mask based on register field
width.
The sequential patches will replace custom div_mask() macro in the
corresponding clock provider modules.

After TESTs, use logically correct JZ mnemonic instead of JE
(this doesn't change code).
Tidy up CMPW insns:
Modern CPUs are not good with 16-bit operations.
The instructions with 16-bit immediates are especially bad,
on many CPUs they cause length changing prefix stall
in the decoders, costing ~
There is no reason to use MOVQ to load a nonnegative immediate
into a 64-bit register. MOVL does the same, since upper 32 bits
are zero extended.

Logically, we just want to jump around the "call *sys_call_table(,%rax,8)"
if syscall number is too big, we do not specifically target
"int_ret_from_sys_call" label.
Use a local numeric label for this jump.
This also makes code smaller because jumps to global labels
are never translated to short
SYSRET code path has a small irq-off block.
On this code path, TRACE_IRQS_ON can't be called right before interrupts
are enabled for real, we can't clobber registers there.
So current code does it earlier, in a safe place.
But with this, TRACE_IRQS_OFF/ON frames just two fast instructions,
