From: "Steven J. Hill" <Steven.Hill@xxxxxxxxxx> This set of patches adds XPA support for R5 and later cores. This has been tested on P5600 platforms only. As noted in the main commit for XPA support, EVA and XPA cannot currently be used at the same time. Leonid Yegoshin (4): MIPS: HIGHMEM fixes for cache aliasing and non-DMA I/O. MIPS: Revert fixrange_init() limiting to the FIXMAP region. MIPS: Rearrange PTE bits into fixed positions for MIPS R2. MIPS: Removal of execute bit in page tables for HEAP/BSS. Markos Chandras (1): MIPS: mm: c-r4k: Ensure CCA is set to non-coherent on UP kernels. Steven J. Hill (6): MIPS: Add CP0 macros for extended EntryLo registers MIPS: Fix address type used for early memory detection. MIPS: Cosmetic cleanups of page table headers. MIPS: Add MFHC0 and MTHC0 instructions to uasm. MIPS: Add support for XPA. MIPS: XPA: Add new configuration file. arch/mips/Kconfig | 35 ++++++ arch/mips/configs/maltaup_xpa_defconfig | 195 +++++++++++++++++++++++++++++++ arch/mips/include/asm/cacheflush.h | 3 +- arch/mips/include/asm/cpu-features.h | 9 ++ arch/mips/include/asm/cpu.h | 1 + arch/mips/include/asm/fixmap.h | 14 ++- arch/mips/include/asm/highmem.h | 44 ++++++- arch/mips/include/asm/mipsregs.h | 40 +++++++ arch/mips/include/asm/page.h | 9 +- arch/mips/include/asm/pgtable-32.h | 109 ++++++++--------- arch/mips/include/asm/pgtable-bits.h | 142 +++++++++++++++++++--- arch/mips/include/asm/pgtable.h | 42 +++---- arch/mips/include/asm/uasm.h | 2 + arch/mips/include/uapi/asm/inst.h | 7 +- arch/mips/kernel/cpu-probe.c | 8 ++ arch/mips/kernel/proc.c | 1 + arch/mips/kernel/setup.c | 2 +- arch/mips/mm/c-r4k.c | 53 ++++++++- arch/mips/mm/cache.c | 83 +++++++++---- arch/mips/mm/highmem.c | 46 +++----- arch/mips/mm/init.c | 48 ++++---- arch/mips/mm/pgtable-64.c | 2 +- arch/mips/mm/sc-mips.c | 1 + arch/mips/mm/tlb-r4k.c | 12 ++ arch/mips/mm/tlbex.c | 88 +++++++++++--- arch/mips/mm/uasm-mips.c | 2 + arch/mips/mm/uasm.c | 14 ++- 27 files changed, 815 insertions(+), 197 deletions(-) create mode 100644 arch/mips/configs/maltaup_xpa_defconfig -- 1.7.10.4
