Without DEBUG_FS, all the code in gup_benchmark becomes meaningless.
For sure kernel provides debugfs stub while DEBUG_FS is disabled, but
the point here is that GUP_BENCHMARK can do nothing without DEBUG_FS.

It is pretty simple when you get down to it.

This patch replaces 6 IWMMXT instructions Clang's integrated assembler
does not support in iwmmxt.S using macros, while making sure GNU
assembler still emit the same instructions. This should be easier than
providing full IWMMXT support in Clang.

Thank you!
The external function definitions don't need the "extern" keyword.
Remove them so future changes don't copy the function definition style.

While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate

PKS allows kernel users to define domains of page mappings which have

Currently struct irqentry_state_t only contains a single bool value

When only user space pkeys are enabled faulting within the kernel was an
unexpected condition which should never happen. Therefore a WARN_ON in
