[Qemu-devel] [PATCH v4 02/13] target-arm: lpae: Make t0sz and t1sz signed integers |
Date: |
Thu, 15 Oct 2015 00:55:35 +0200 |
From: "Edgar E. Iglesias" <address@hidden>
Make t0sz and t1sz signed integers to match tsz and to make
it easier to implement support for AArch32 negative t0sz.
t1sz is changed for consistensy.
No functional change.
