Subject: [PATCH 00/18] Pile o' entry/exit/sp0 changes
Date: Thu, 26 Oct 2017 01:26:32 -0700 [thread overview]
Message-ID: <cover.1509006199.git.luto@kernel.org> (raw)
Hi all-
Here's the first "real" version of this series. It's based on Linus'
tree from a couple days ago.
Changes from the old RFC version:
- Rebase
- Add Juergen's patch
- Add some assertions
- Cleanups
Andy Lutomirski (17):
x86/asm/64: Remove the restore_c_regs_and_iret label
x86/asm/64: Split the iret-to-user and iret-to-kernel paths
x86/asm/64: Move SWAPGS into the common iret-to-usermode path
x86/asm/64: Simplify reg restore code in the standard IRET paths
x86/asm/64: Shrink paranoid_exit_restore and make labels local
x86/asm/64: Use pop instead of movq in syscall_return_via_sysret
x86/asm/64: Merge the fast and slow SYSRET paths
x86/asm/64: De-Xen-ify our NMI code
x86/asm/32: Pull MSR_IA32_SYSENTER_CS update code out of
native_load_sp0()
x86/asm/64: Pass sp0 directly to load_sp0()
x86/asm: Add task_top_of_stack() to find the top of a task's stack
x86/xen/64: Clean up SP code in cpu_initialize_context()
x86/boot/64: Stop initializing TSS.sp0 at boot
x86/asm/64: Remove all remaining direct thread_struct::sp0 reads
x86/boot/32: Fix cpu_current_top_of_stack initialization at boot
x86/asm/64: Remove thread_struct::sp0
x86/traps: Use a new on_thread_stack() helper to clean up an assertion
Juergen Gross (1):
xen: add xen nmi trap entry
