Subject: [GIT PULL] x86 fixes
Date: Sat, 1 Aug 2015 10:44:56 +0200 [thread overview]
Message-ID: <20150801084456.GA13068@gmail.com> (raw)
Linus,

# HEAD: 37868fe113ff2ba814b3b4eb12df214df555f8dc x86/ldt: Make modify_ldt synchronous
Fallout from the recent NMI fixes: make x86 LDT handling more robust.
Also some EFI fixes.
out-of-topic modifications in x86-urgent-for-linus:
-----------------------------------------------------
drivers/firmware/efi/efi.c # 9115c7589b11: efi: Check for NULL efi kern
Thanks,
Ingo
------------------>
Andy Lutomirski (2):
x86/xen: Probe target addresses in set_aliased_prot() before the hypercall
x86/ldt: Make modify_ldt synchronous
Dmitry Skorodumov (1):
x86/efi: Use all 64 bit of efi_memmap in setup_e820()
Jiang Liu (1):
x86/irq: Use the caller provided polarity setting in mp_check_pin_attr()
Ricardo Neri (1):
efi: Check for NULL efi kernel parameters
