[PATCH 20/35] [PATCH 20/36] MIPS: Replace __get_cpu_var uses in FPU emulator.

[-- Attachment #1: 0020-MIPS-Replace-__get_cpu_var-uses-in-FPU-emulator.patch --]
[-- Type: text/plain, Size: 1625 bytes --]

The use of __this_cpu_inc() requires a fundamental integer type, so
change the type of all the counters to unsigned long, which is the
same width they were before, but not wrapped in local_t.
