Subject: [GIT PULL] x86 fixes
Date: Fri, 20 Feb 2015 14:47:52 +0100 [thread overview]
Message-ID: <20150220134752.GA31370@gmail.com> (raw)
Linus,
Please pull the latest x86-urgent-for-linus git tree from:

# HEAD: 570e1aa84c376ff39809442f09c7606ddf62cfd1 x86/mm/ASLR: Avoid PAGE_SIZE redefinition for UML subarch
This tree contains:
- EFI fixes
- a boot printout fix
- ASLR/kASLR fixes
- intel microcode driver fixes
- other misc fixes
Most of the linecount comes from an EFI revert.

/*
* Copyright (C) 2014 Intel Corporation; author Matt Fleming
+ *
+ * Support for invoking 32-bit EFI runtime services from a 64-bit
+ * kernel.
+ *
+ * The below thunking functions are only used after ExitBootServices()
+ * has been called. This simplifies things considerably as compared with
+ * the early EFI thunking because we can leave all the kernel state
+ * intact (GDT, IDT, etc) and simply invoke the the 32-bit EFI runtime
+ * services from __KERNEL32_CS. This means we can continue to service
+ * interrupts across an EFI mixed mode call.
+ *
+ * We do however, need to handle the fact that we're running in a full
+ * 64-bit virtual address space. Things like the stack and instruction
+ * addresses need to be accessible by the 32-bit firmware, so we rely on
+ * using the identity mappings in the EFI page table to access the stack
+ * and kernel text (see efi_setup_page_tables()).
