H A D | cpu-probe.c | 0f2d988d Tue May 17 18:08:49 CDT 2016 James Hogan <james.hogan@imgtec.com> MIPS: Fix incomplete separation of XPA CPU feature
Commit 12822570a29b ("MIPS: Separate XPA CPU feature into LPA and MVH") wasn't fully applied, possibly due to a conflict with commit f270d881fa55 ("MIPS: Detect MIPSr6 Virtual Processor support"). This left decode_config5() referring to the non-existent MIPS_CPU_XPA, which breaks the build when XPA is enabled:
arch/mips/kernel/cpu-probe.c In function ‘decode_config5’: arch/mips/kernel/cpu-probe.c:838:17: error: ‘MIPS_CPU_XPA’ undeclared (first use in this function) c->options |= MIPS_CPU_XPA; ^
Apply the missing hunk, dropping the CONFIG_XPA ifdef and setting the MIPS_CPU_MVH option when Config5.MVH is set.

XPA (eXtended Physical Addressing) should be detected as a combination of two architectural features: - Large Physical Address (as per Config3.LPA). With XPA this will be set on MIPS32r5 cores, but it may also be set for MIPS64r2 cores too. - MTHC0/MFHC0 instructions (as per Config5.MVH). With XPA this will be set, but it may also be set in VZ guest context even when Config3.LPA in the guest context has been cleared by the hypervisor.
As such, XPA is only usable if both bits are set. Update CPU features to separate these two features, with cpu_has_xpa requiring both to be set.
