Subject: [PATCH 01/17] tile: Fix __pte_free_tlb
Date: Thu, 17 Feb 2011 17:23:28 +0100 [thread overview]
Message-ID: <20110217163234.756898524@chello.nl> (raw)
In-Reply-To: 20110217162327.434629380@chello.nl
[-- Attachment #1: tile-fix-pte_free_tlb.patch --]
[-- Type: text/plain, Size: 1420 bytes --]
Tile's __pte_free_tlb() implementation makes assumptions about the
generic mmu_gather implementation, cure this ;-)
