The versions of the __write_{32,64}bit_gc0_register() macros for when there is no virt support in the assembler use the "J" inline asm constraint to allow integer zero, but this needs to be accompanied by the "z" formatting string so that it turns into $0. Fix both macros to do this.

When starting secondary VPEs which support EVA and the SegCtl registers, copy the memory segmentation configuration from the running VPE to ensure that all VPEs in the core have a consistent virtual memory map. The EVA configuration of secondary cores is dealt with when starting the core via the CM. Signed-off-by:

Commit 12822570 ("MIPS: Separate XPA CPU feature into LPA and MVH") wasn't fully applied, possibly due to a conflict with commit f270d881 ("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.

When EIC mode is in use (cpu_has_veic is true) enable it on each CPU during GIC initialisation. Otherwise there may be a mismatch between the hardware default interrupt model & that expected by the kernel. Signed-off-by:

When using an external interrupt controller (EIC) the interrupt mask bits in the cop0 Status register are reused for the Interrupt Priority Level, and any interrupts with a priority lower than the field will be ignored. Clear the field to 0 by default such that all interrupts are serviced. Signed-off-by:

Clear the field to 0 by default such that all interrupts are serviced. Without doing so we default to arbitrarily ignoring all or some subset of interrupts. Signed-off-by:

PIC32 clock driver is now implemented as platform driver instead of as part of of_clk_init(). It meants all the clock modules are available quite late in the boot sequence. So request for CPU clock by clk_get_sys() and clk_get_rate() to find c0_timer rate fails. To fix this use PIC32 specific early clock functions implemented for early console support. Signed-off-by:

The VZ guest register & TLB access macros introduced in commit "MIPS: Add guest CP0 accessors" use VZ ASE specific instructions that aren't understood by versions of binutils prior to 2.24. Add a check for whether the toolchain supports the -mvirt option, similar to the MSA toolchain check, and implement the accessors using .word if not. Due to difficulty in converting compiler specified registers (e.g. "$3") to usable numbers (e.g. "3") in inline asm, we need to copy to/from a temporary register, namely the assembler temporary (at/$1), and specify guest CP0 registers numerically in the gc0 macros.

Fix a build regression from commit c9017757 ("MIPS: init upper 64b of vector registers when MSA is first used"): arch/mips/built-in.o: In function `enable_restore_fp_context': traps.c:(.text+0xbb90): undefined reference to `_init_msa_upper' traps.c:(.text+0xbb90): relocation truncated to fit: R_MIPS_26 against `_init_msa_upper' traps.c:(.text+0xbef0): undefined reference to `_init_msa_upper' traps.c:(.text+0xbef0): relocation truncated to fit: R_MIPS_26 against `_init_msa_upper' to !CONFIG_CPU_HAS_MSA configurations with older GCC versions, which are unable to figure out that calls to `_init_msa_upper' are indeed dead. Of the many ways to tackle this failure choose the approach we have already taken in `thread_msa_context_live'. [ralf@linux-mips.org: Drop patch segment to junk file.] Signed-off-by:
