From e5eb925a1804c4a52994ba57f4f68ee7a9132905 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 21 May 2014 11:42:10 +0200 Subject: [PATCH] MIPS: Change type of asid_cache to unsigned long asid_cache must be unsigned long otherwise on 64 bit systems it will become 0 if the value in get_new_mmu_context() reaches 0xffffffff and in the end the assumption of ASID_FIRST_VERSION is not true anymore thus leads to more dangerous things.
