-Subject: MIPS: Fix C0_Pagegrain[IEC] support.
-
-From: David Daney <david.daney@cavium.com>
-
-commit 9ead8632bbf454cfc709b6205dc9cd8582fb0d64 upstream.
-
-The following commits:
-
-  5890f70f15c52d (MIPS: Use dedicated exception handler if CPU supports RI/XI exceptions)
-  6575b1d4173eae (MIPS: kernel: cpu-probe: Detect unique RI/XI exceptions)
-
-break the kernel for *all* existing MIPS CPUs that implement the
-CP0_PageGrain[IEC] bit.  They cause the TLB exception handlers to be
-generated without the legacy execute-inhibit handling, but never set
-the CP0_PageGrain[IEC] bit to activate the use of dedicated exception
-vectors for execute-inhibit exceptions.  The result is that upon
-detection of an execute-inhibit violation, we loop forever in the TLB
-exception handlers instead of sending SIGSEGV to the task.
-
-If we are generating TLB exception handlers expecting separate
-vectors, we must also enable the CP0_PageGrain[IEC] feature.
-
-The bug was introduced in kernel version 3.17.
