Subject: seabios: increase smp_mtrr array size
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=seabios.git;a=commitdiff_plain;h=bbce6d63c18b85710b1e567a3035914c5ac13ccf

seabios: increase smp_mtrr array size

Windows Server 2008 checked build complains about lack of consistency
between MTRR MSRs in SMP guests.

Problem is the smp_mtrr array is not large enough to hold all MSRs (31
entries with current qemu/kvm implementations).

Increase it to 32.
