Subject: [PATCH 4.1 00/65] page table isolation for stable 4.1
The git of this backport can be found here:
git clone --branch pti_v4.1.49 https://github.com/soleen/linux
The patches were backported from stable 4.4 to Oracle UEK4.1, and from
UEK4.1 to Stable 4.1
Aaron Lu (1):
x86/irq: Do not substract irq_tlb_count from irq_call_count
Andy Lutomirski (16):
x86/mm: Add INVPCID helpers
x86/mm: Add a 'noinvpcid' boot option to turn off INVPCID
x86/mm: If INVPCID is available, use it to flush global mappings
sched/core: Add switch_mm_irqs_off() and use it in the scheduler
x86/mm: Build arch/x86/mm/tlb.c even on !SMP
x86/mm, sched/core: Turn off IRQs in switch_mm()
sched/core: Idle_task_exit() shouldn't use switch_mm_irqs_off()
x86/vm86/32: Switch to flush_tlb_mm_range() in mark_screen_rdonly()
x86/mm: Remove flush_tlb() and flush_tlb_current_task()
x86/mm: Make flush_tlb_mm_range() more predictable
x86/mm: Reimplement flush_tlb_page() using flush_tlb_mm_range()
x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly)
SMP code
x86/mm: Disable PCID on 32-bit kernels
x86/mm: Add the 'nopcid' boot option to turn off PCID
x86/mm: Enable CR4.PCIDE on supported systems

x86/kaiser: Check boottime cmdline params
x86/kaiser: Reenable PARAVIRT
x86/kaiser: Move feature detection up
Dave Hansen (2):
kaiser: merged update
kaiser: enhanced by kernel and user PCIDs
Denys Vlasenko (3):
x86/entry: Stop using PER_CPU_VAR(kernel_stack)
x86/entry: Remove unused 'kernel_stack' per-cpu variable
x86/entry: Define 'cpu_current_top_of_stack' for 64-bit code
Hugh Dickins (26):
kaiser: do not set _PAGE_NX on pgd_none
kaiser: stack map PAGE_SIZE at THREAD_SIZE-PAGE_SIZE
kaiser: fix build and FIXME in alloc_ldt_struct()
kaiser: KAISER depends on SMP
kaiser: fix regs to do_nmi() ifndef CONFIG_KAISER
kaiser: fix perf crashes

kaiser: load_new_mm_cr3() let SWITCH_USER_CR3 flush user
kaiser: PCID 0 for kernel and 128 for user
kaiser: x86_cr3_pcid_noflush and x86_cr3_pcid_user
kaiser: paranoid_entry pass cr3 need to paranoid_exit
kaiser: _pgd_alloc() without __GFP_REPEAT to avoid stalls
kaiser: fix unlikely error in alloc_ldt_struct()
kaiser: add "nokaiser" boot option, using ALTERNATIVE
kaiser: add "nokaiser" boot option, using ALTERNATIVE
kaiser: use ALTERNATIVE instead of x86_cr3_pcid_noflush
kaiser: drop is_atomic arg to kaiser_pagetable_walk()
kaiser: asm/tlbflush.h handle noPGE at lower level
kaiser: kaiser_flush_tlb_on_return_to_user() check PCID
