Subject: [PATCH] gts and bfs fixes (v4).

v2 [https://lkml.org/lkml/2012/4/9/474]
 - ditched the assembler version and used a C wrapper

With git commit a2ef5c4fd44ce3922435139393b89f2cce47f576
"ACPI: Move module parameter gts and bfs to sleep.c" the
sampling of gts/bfs module parameters flag by acpi_enter_sleep_state
has been moved. It has been moved out of the inner ACPI code and
out in the more x86 specific. This means that any caller of
the exported acpi_enter_sleep_state function needs to provide
two parameters now: sleep state and the bit flag whether to us _GTS|_BFS.

All of the callers of acpi_enter_sleep_state did that, with
the exception of the assembler version and as well any
third-party callers of acpi_enter_sleep_state.

These two patches expose 'wake_sleep_flags' as the product
of the gts/bfs module parameter invocation. And also use said
flag in the assembler 'do_suspend_lowlevel()' function.

Konrad Rzeszutek Wilk (2):
      ACPI: Convert wake_sleep_flags to a value instead of function (v4)
      x86/acpi: Call acpi_enter_sleep_state via an asmlinkage C function from assembler.
