From 48c4ac976ae995f263cde8f09578de86bc8e9f1d Mon Sep 17 00:00:00 2001 From: David Daney Date: Mon, 13 May 2013 13:56:44 -0700 Subject: Revert "MIPS: Allow ASID size to be determined at boot time." This reverts commit d532f3d26716a39dfd4b88d687bd344fbe77e390. The original commit has several problems: 1) Doesn't work with 64-bit kernels. 2) Calls TLBMISS_HANDLER_SETUP() before the code is generated. 3) Calls TLBMISS_HANDLER_SETUP() twice in per_cpu_trap_init() when only one call is needed. [ralf@linux-mips.org: Also revert the bits of the ASID patch which were hidden in the KVM merge.] Signed-off-by: David Daney Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: "Steven J.
