Add new memory layout 2.5G(user):1.5G(kernel) - Add kmemleak support - Reconstruct VDSO framework Add VDSO with GENERIC_GETTIMEOFDAY, GENERIC_TIME_VSYSCALL, HAVE_GENERIC_VDSO - Add faulthandler_disabled() check - Support(Fixup) swapon - Add(Fixup) _PAGE_ACCESSED for default pgprot - abort uaccess retries upon fatal signal (From arm) Fixup & Optimization: - Fixup perf probe failed - Fixup show_regs doesn't contain regs->usp - Remove custom asm/atomic.h implementation - Fixup barrier design - Fixup futex SMP implementation - Fixup asm/cmpxchg.h with correct ordering barrier - Cleanup asm/spinlock.h - Fixup PTE global for 2.5:1.5 virtual memory - Remove prologue of page fault handler in entry.S - Fix TLB maintenance synchronization problem - Add show_tlb for CPU_CK860 debug - Fixup FAULT_FLAG_XXX param for handle_mm_fault - Fixup update_mmu_cache called with user io mapping - Fixup do_page_fault parent irq status - Fix a size determination in gpr_get() - pgtable.h: Coding convention - kprobe: Fixup code in simulate without 'long' - Fixup pfn_valid error with wrong max_mapnr - use free_initmem_default() in free_initmem() - Fixup compile error ---------------------------------------------------------------- David Hildenbrand (1): csky: use free_initmem_default() in free_initmem() Guo Ren (27): csky: Add memory layout 2.5G(user):1.5G(kernel) csky: Fixup perf probe failed csky: Fixup show_regs doesn't contain regs->usp csky: Remove custom asm/atomic.h implementation csky: Fixup barrier design csky: Fixup futex SMP implementation csky: Fixup asm/cmpxchg.h with correct ordering barrier csky: Cleanup asm/spinlock.h csky: Fixup PTE global for 2.5:1.5 virtual memory csky: Remove prologue of page fault handler in entry.S csky: Add kmemleak support csky: Fix TLB maintenance synchronization problem csky: Add show_tlb for CPU_CK860 debug csky: Fixup FAULT_FLAG_XXX param for handle_mm_fault csky: Fixup update_mmu_cache called with user io mapping csky: Add faulthandler_disabled() check csky: Fixup do_page_fault parent irq status csky: Sync riscv mm/fault.c for easy maintenance csky: mm: abort uaccess retries upon fatal signal csky: Reconstruct VDSO framework csky: Fixup _PAGE_ACCESSED for default pgprot csky: pgtable.h: Coding convention csky: Fixup swapon csky: kprobe: Fixup code in simulate without 'long' csky: Add VDSO with GENERIC_GETTIMEOFDAY, GENERIC_TIME_VSYSCALL, HAVE_GENERIC_VDSO csky: Fixup pfn_valid error with wrong max_mapnr csky: Fixup compile error Tian Tao (1): csky: remove unused including <linux/version.h> Zhenzhong Duan (1): csky: Fix a size determination in gpr_get() arch/csky/Kconfig | 24 +- arch/csky/abiv1/inc/abi/cacheflush.h | 1 -
