Subject: [patch 17/26] Add text_poke and sync_core to powerpc
Date: Thu, 24 Jan 2008 15:27:23 -0500 [thread overview]
Message-ID: <20080124203339.558298901@polymtl.ca> (raw)
In-Reply-To: 20080124202706.250598537@polymtl.ca
[-- Attachment #1: add-text-poke-to-powerpc.patch --]
[-- Type: text/plain, Size: 1355 bytes --]
- Needed on architectures where we must surround live instruction modification
with "WP flag disable".
- Turns into a memcpy on powerpc since there is no WP flag activated for
instruction pages (yet..).
- Add empty sync_core to powerpc so it can be used in architecture independent
code.
