Subject: [PATCH] agp/intel: Fix typo in G4x_GMCH_SIZE_VT_2M
Date: Tue, 12 Jul 2011 19:27:12 +0100	[thread overview]
Message-ID: <1310495232-21102-1-git-send-email-chris@chris-wilson.co.uk> (raw)

Konstantin Belousov found an error in the define of G4x_GMCH_SIZE_VT_2M
relative to the GMCH specs, and confirmed that indeed one of his users
with a Q45 reports 0xb not 0xc for a 2/2MiB GATT.

v2: Fixed typo spotted by Konstantin.
