[PATCH 3/7] x86: mtrr: Skip MSRs that were already programmed in mtrr_commit()

At present mtrr_commit() programs the MTRR MSRs starting from index 0, which may overwrite MSRs that were already programmed by previous boot stage or FSP. Switch to call mtrr_set_next_var() instead. Signed-off-by: Bin Meng --- arch/x86/cpu/mtrr.c | 2 +- 1 file changed, 1 insertion(+), 1 dele
