Subject: [patch 7/8] powerpc: Cleanup PCL output by hiding and adding symbols
Date: Wed, 01 Jul 2009 09:00:50 +1000	[thread overview]
Message-ID: <20090630230141.294083597@samba.org> (raw)
In-Reply-To: 20090630230043.464194676@samba.org

[-- Attachment #1: pci_make_symbols_local.patch --]
[-- Type: text/plain, Size: 1516 bytes --]

A lot of hits in "setup" doesn't make much sense, so hide this symbol and
allow all the hits to end up in copy_4k_page.

Also add some dummy symbols for the branches at 0xf00, 0xf20 and 0xf40,
otherwise hits end up in trap_0e which is confusing.
