+Subject: MIPS: Allow emulation for unaligned [LS]DXC1 instructions
+
+If an address error exception occurs for a LDXC1 or SDXC1 instruction,
+within the cop1x opcode space, allow it to be passed through to the FPU
+emulator rather than resulting in a SIGILL. This causes LDXC1 & SDXC1 to
+be handled in a manner consistent with the more common LDC1 & SDC1
+instructions.

+Add basic CN7XXX interface detection.
+
+This allows the kernel to boot with ethernet working as it initializes

+
+Tested on the utm8 from Rhino Labs with a CN7130.

+Subject: MIPS: Prevent "restoration" of MSA context in non-MSA kernels
+
+If a kernel doesn't support MSA context (ie. CONFIG_CPU_HAS_MSA=n) then
+it will only keep 64 bits per FP register in thread context, and the
+calls to set_fpr64 in restore_msa_extcontext will overrun the end of the
+FP register context into the FCSR & MSACSR values. GCC 6.x has become
+smart enough to detect this & complain like so:
+
+ arch/mips/kernel/signal.c: In function 'protected_restore_fp_context':
+ ./arch/mips/include/asm/processor.h:114:17: error: array subscript
is above array bounds [-Werror=array-bounds]
+ fpr->val##width[FPR_IDX(width, idx)] = val; \
+ ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~
+ ./arch/mips/include/asm/processor.h:118:1: note: in expansion of
macro 'BUILD_FPR_ACCESS'
+ BUILD_FPR_ACCESS(64)
+
+The only way to trigger this code to run would be for a program to set
+up an artificial extended MSA context structure following a sigframe &
+execute sigreturn. Whilst this doesn't allow a program to write to any
+state that it couldn't already, it makes little sense to allow this
+"restoration" of MSA context in a system that doesn't support MSA.
+
+Fix this by killing a program with SIGSYS if it tries something as crazy
+as "restoring" fake MSA context in this way, also fixing the build error
+& allowing for most of restore_msa_extcontext to be optimised out of
+kernels without support for MSA.
