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. Changes from V1: - Remove fixrange_init() revert patch. - Remove CCA patch. - Remove HEAP/BSS execute bit removal patch. - Updated __writex_32bit_c0_register() to use %1 instead of the macro variable name. Leonid Yegoshin (2): MIPS: HIGHMEM fixes for cache aliasing and non-DMA I/O. MIPS: Rearrange PTE bits into fixed positions for MIPS R2. 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 | 5 +- 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 | 40 ++++++- arch/mips/mm/cache.c | 83 +++++++++---- arch/mips/mm/highmem.c | 46 +++----- arch/mips/mm/init.c | 42 ++++--- 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 ++- 26 files changed, 797 insertions(+), 190 deletions(-) create mode 100644 arch/mips/configs/maltaup_xpa_defconfig -- 1.7.10.4
