Pu Wen 39dc6f154d x86/cpu/mtrr: Support TOP_MEM2 and get MTRR number 
The Hygon Dhyana CPU has a special MSR way to force WB for memory >4GB,
and support TOP_MEM2. Therefore, it is necessary to add Hygon Dhyana
support in amd_special_default_mtrr().

The number of variable MTRRs for Hygon is 2 as AMD's.

Joe Perches e6d8c84a58 x86/mtrr: Rename main.c to mtrr.c and remove duplicate prefixes 
Kbuild uses the first file as the name for KBUILD_MODNAME.
mtrr uses main.c as its first file, so rename that file to mtrr.c
and fixup the Makefile.

Remove the now duplicate "mtrr: " prefixes from the logging calls.
