Right now the module capability is cauing more trouble
than it is worth. At least one distro built intel_idle as a module
where it lost the init race with ACPI, making it useless.
Make intel_idle bool so that if you select it, you will use it.
We can restore module capability after cpuidle is enhanced
to handle run-time changing of idle drivers.

The 32-bit assembly is guarded by an #ifndef CONFIG_X86_64. Kconfig prevents

This driver supports both iLO2 and iLO3, but our user-visible strings
currently only reference iLO2. Let's just call it "iLO2+" to avoid having
to update strings for each iLO generation. This driver doesn't support
iLO ASICs prior to iLO2, but that is sufficiently explained in Kconfig.

But if that *fails*, the acpi_video driver was never getting registered.

mmc_test provides tests aimed at testing SD/MMC hosts. This patch adds
performance tests.
It is advantageous to have performance tests in a kernel
module like mmc_test for the following reasons:
- transfer times can be measured very accurately
- arbitrarily large transfers are possible
- the effect of contiguous vs scattered pages
can be determined
The new tests are:
23. Best-case read performance
24. Best-case write performance
25. Best-case read performance into scattered pages
26. Best-case write performance from scattered pages
27. Single read performance by transfer size
28. Single write performance by transfer size
29. Single trim performance by transfer size
30. Consecutive read performance by transfer size
31. Consecutive write performance by transfer size
32. Consecutive trim performance by transfer size
