  x86: Drop bogus __ref / __refdata annotations

bus: subsys: update return type of ->remove_dev() to void

2015-08-06T00:08:14+00:00

Its return value is not used by the subsys core and nothing meaningful
can be done with it, even if we want to use it. The subsys device is
anyway getting removed.

Update prototype of ->remove_dev() to make its return type as void. Fix
all usage sites as well.

x86: Drop bogus ref / refdata annotations

2015-07-20T16:57:20+00:00

The __ref / __refdata annotations used to be needed because of
referencing functions / variables annotated __cpuinit /
__cpuinitdata.

But those annotations vanished during the development of v3.11.

Therefore most of the __ref / __refdata annotations are not needed
anymore. As they may hide legitimate sections mismatches, we
better get rid of them.

x86/microcode: Correct CPU family related variable types

2015-06-07T13:38:15+00:00

Change the type of variables and function prototypes to be in
alignment with what the x86_*() / __x86_*() family/model
functions return.

x86/microcode: Disable builtin microcode loading on 32-bit for now

2015-06-07T13:38:14+00:00

Andy Shevchenko reported machine freezes when booting latest tip
on 32-bit setups. Problem is, the builtin microcode handling cannot
really work that early, when we haven't even enabled paging.

A proper fix would involve handling that case specially as every
other early 32-bit boot case in the microcode loader and would
require much more involved changes for which it is too late now,
more than a week before the upcoming merge window.

So, disable the builtin microcode loading on 32-bit for now.

x86/microcode/intel: Simplify update_match_cpu()

2015-05-18T07:32:36+00:00

Drop unreadable macro, deconstruct compound conditional
statement into single ones and return early if they match. Add
comments.

There should be no functionality change resulting from this
patch.
