Subject: [Qemu-devel] [PATCH, MIPS64] Fix Status_rw_bitmask values
Date: Mon, 4 Jun 2007 23:37:47 +0200	[thread overview]
Message-ID: <20070604213747.GA8768@farad.aurel32.net> (raw)

Hi all,

The patch below fixes the Status_rw_bitmask values for 64-bit CPUs:
- Reverse endianess is currently not implemented, the RE bit should
  not be writable. 
- 64-bit is implemented, the PX bit should be writable.

Bye,
Aurelien
