From 3989efb77046ad334518b6cddcf817184affe7c9 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Thu, 1 Dec 2011 11:37:20 -0500 Subject: arch/tile: add a few #includes and an EXPORT to catch up with kernel changes. The empty_zero_page[] export is required for ZERO_PAGE() module references. The #includes are due to changes in implicit inclusion, and should of course have been in the sources from the beginning.

This will allow follow on patches to create a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over-ridden by architecture-specific code. Converting 'pci_bios_set_master()' to a non-inlined function will allow TILE's 'pcibios_set_master()' implementation to remain architecture-specific after the generic version is introduced and thus, not change current behavior. No functional change.
