2013-04-26Merge tag 'efi-urgent' into x86/urgentH. Peter Anvin1-2/+2
* The EFI variable anti-bricking algorithm merged in -rc8 broke booting on some Apple machines because they implement EFI spec 1.10, which doesn't provide a QueryVariableInfo() runtime function and the logic used to check for the existence of that function was insufficient. Fix from Josh Boyer. * The anti-bricking algorithm also introduced a compiler warning on 32-bit. Fix from Borislav Petkov. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2013-04-26parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updatesJohn David Anglin2-26/+26
User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency.

2013-04-26parisc: disable -mlong-calls compiler option for kernel modulesHelge Deller1-2/+4
CONFIG_MLONGCALLS was introduced in commit ec758f98328da3eb933a25dc7a2eed01ef44d849 to overcome linker issues when linking huge linux kernels, e.g. with many modules linked in. But in the kernel module loader there is no support yet for the new relocation types, which is why modules built with -mlong-calls can't be loaded. Furthermore, for modules long calls are not really necessary, since we already use stub sections which resolve long distance calls. So, let's just disable this compiler option when compiling kernel modules. Signed-off-by: Helge Deller <deller@gmx.de>
2013-04-26parisc: uaccess: fix compiler warnings caused by __put_user castingWill Deacon1-10/+4
When targetting 32-bit processors, __put_user emits a pair of stw instructions for the 8-byte case. If the type of __val is a pointer, the marshalling code casts it to the wider integer type of u64, resulting in the following compiler warnings: kernel/signal.c: In function 'copy_siginfo_to_user': kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] This patch fixes the warnings by removing the marshalling code and using the correct output modifiers in the __put_{user,kernel}_asm64 macros so that GCC will allocate the right registers without the need to extract the two words explicitly.

2013-04-24efi: Check EFI revision in setup_efi_varsJosh Boyer1-1/+1
We need to check the runtime sys_table for the EFI version the firmware specifies instead of just checking for a NULL QueryVariableInfo. Older implementations of EFI don't have QueryVariableInfo but the runtime is a smaller structure, so the pointer to it may be pointing off into garbage. This is apparently the case with several Apple firmwares that support EFI 1.10, and the current check causes them to no longer boot. Fix based on a suggestion from Matthew Garrett.

This reverts commit c17a6554782ad531f4713b33fd6339ba67ef6391. Manuel Lauss writes: lmo commit c17a6554 (MIPS: page.h: Provide more readable definition for PAGE_MASK) apparently breaks ioremap of 36-bit addresses on my Alchemy systems (PCI and PCMCIA) The reason is that in arch/mips/mm/ioremap.c line 157 (phys_addr &= PAGE_MASK) bits 32-35 are cut off. Seems the new PAGE_MASK is explicitly 32bit, or one could make it signed instead of unsigned long.
