Folks, please pull the single below fix from Omar which fixes a kexec boot regression. I've based the pull on tip/efi/urgent since the EFI urgent queue hasn't reached Linus' tree yet.

[GIT PULL] EFI urgent fix
Folks, the LKP robot reported an issue with Paolo's recent bug fix that syncs the identity mapping in 'initial_page_table'. Turns out that KERNEL_PGD_PTRS is not the correct constant to use when copying to the lower region because that's every PGD from PAGE_OFFSET to the end of the addressable memory. Crucially, KERNEL_PGD_PTRS > KERNEL_PGD_BOUNDARY and so the patch ends up trashing some of the kernel mappings in 'initial_page'table, leading to boot crashes on 32-bit SMP when bringing APs online. The following changes since commit 9ee870feaa9e0c6abef95a3b1fc518d88adfa2d3: Merge branch 'x86/cpufeature' into x86/urgent, to pick up pending Intel MID change (2015-11-03 12:00:40 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-urgent for you to fetch changes up to 5965d1bbeba70fe3626e4537f4729283cb0e75f7: x86/setup: Fix recent boot crash on 32-bit SMP machines (2015-11-04 09:26:24 +) * Avoid trashing the kernel mappings in 'initial_page_table' when copying the identity mapping from 'swapper_pg_dir'. This bug was introduced by a bug fix in v4.3 which erroneously copies too many entries from 'swapper_pg_dir'.

[GIT PULL] EFI urgent fix
From: Matt Fleming Folks, the below fix from Paolo addresses an issue causing 32-bit non-PAE kernels to triple fault on EFI boot. The issue is that the physical address of the GDT that gets used in efi_call_phys_prolog() won't be covered by the identitty mapping in initial_page_table. The following changes since commit 8a53554e12e98d1759205afd7b8e9e2ea0936f48: x86/efi: Fix multiple GOP device support (2015-10-14 16:02:43 +0200) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-urgent for you to fetch changes up to f5f3497cad8c8416a74b9aaceb127908755d020a: x86/setup: Extend low identity map to cover whole kernel range (2015-10-16 10:52:29 +0100) * Ensure that the identity mapping in initial_page_table is updated to cover the entire kernel range.

Hi guys, Please consider pulling the following urgent fix from Dave. It fixes an earlyprintk=efi regression introduced in v3.16.

I already took this from the earlier email you sent. Did it change since? Nope, there hasn't been any change. I just didn't know whether you preferred to take the fix via email or a pull request.

[GIT PULL] EFI urgent fix
Hi Peter, Linus, I've got a small patch that fixes a crash for the Google folks and their EFI SMI driver, which was caused by dereferencing a garbage pointer. Please consider pulling. The following changes since commit f697036b93aa7345d4cbb3c854a76456c0ddac45: efi: Check EFI revision in setup_efi_vars (2013-04-24 16:19:01 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-urgent for you to fetch changes up to 45432323ef7038a91599959173700fdb8a0adb2f: efivars: only check for duplicates on the registered list (2013-04-26 16:50:01 +0100) * Last minute bugfix for the efivars code. The google EFI SMI driver maintains its own list of EFI variables but the efivars core was directly accessing a different (and in this case, uninitialised) list resulting in a crash.
