Browse Source 
Upstream changes in mips specific code of the last release broke build
for that target. Add a patch that restores build.

Subject: [PATCH] Fix build for mips targets
Commit 917c2ccf3a67 ("Refactor stack pointers") removed
linux/mips/arch_regs.h that defines mips_REG_* macros and struct
mips_regs. These symbols are referenced in mips code. Restore
arch_regs.h to fix the build failure:
syscall.c: In function 'decode_syscall_subcall':
syscall.c:370:7: error: 'mips_REG_SP' undeclared (first use in this function)
mips_REG_SP + MAX_ARGS * sizeof(tcp->u_arg[0]),
^~~~~~~~~~~
[ baruch: drop the Makefile.in hunk to avoid autoreconf ]
