2023-06-01x86/mtrr: Allocate mtrr_value array dynamicallyJuergen Gross
The mtrr_value[] array is a static variable which is used only in a few configurations. Consuming 6kB is ridiculous for this case, especially as the array doesn't need to be that large and it can easily be allocated dynamically.

2023-06-01x86/mtrr: Move 32-bit code from mtrr.c to legacy.cJuergen Gross
There is some code in mtrr.c which is relevant for old 32-bit CPUs only. Move it to a new source legacy.c. While modifying mtrr_init_finalize() fix spelling of its name.
