2015-05-08ARM: replace BSYM() with badr assembly macroRussell King13-28/+41
BSYM() was invented to allow us to work around a problem with the assembler, where local symbols resolved by the assembler for the 'adr' instruction did not take account of their ISA. Since we don't want BSYM() used elsewhere, replace BSYM() with a new macro 'badr', which is like the 'adr' pseudo-op, but with the BSYM() mechanics integrated into it. This ensures that the BSYM()-ification is only used in conjunction with 'adr'.

2015-05-08ARM: kvm: fix a bad BSYM() usageRussell King1-1/+1
BSYM() should only be used when refering to local symbols in the same assembly file which are resolved by the assembler, and not for linker-fixed up symbols. The use of BSYM() with panic is incorrect as the linker is involved in fixing up this relocation, and it knows whether panic() is ARM or Thumb.

2015-04-26x86_64, asm: Work around AMD SYSRET SS descriptor attribute issueAndy Lutomirski5-0/+48
AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used. Work around the issue by setting SS to __KERNEL_DS __switch_to, thus ensuring that SYSRET never happens with SS set to NULL. This was exposed by a recent vDSO cleanup.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull initial ACPI support for arm64 from Will Deacon: "This series introduces preliminary ACPI 5.1 support to the arm64 kernel using the "hardware reduced" profile. We don't support any peripherals yet, so it's fairly limited in scope: - MEMORY init (UEFI) - ACPI discovery (RSDP via UEFI) - CPU init (FADT) - GIC init (MADT) - SMP boot (MADT + PSCI) - ACPI Kconfig options (dependent on EXPERT) ACPI for arm64 has been in development for a while now and hardware has been available that can boot with either FDT or ACPI tables. This has been made possible by both changes to the ACPI spec to cater for ARM-based machines (known as "hardware-reduced" in ACPI parlance) but also a Linaro-driven effort to get this supported on top of the Linux kernel. This pull request is the result of that work. These changes allow us to initialise the CPUs, interrupt controller, and timers via ACPI tables, with memory information and cmdline coming from EFI. We don't support a hybrid ACPI/FDT scheme. Of course, there is still plenty of work to do (a serial console would be nice!) but I expect that to happen on a per-driver basis after this core series has been merged. Anyway, the diff stat here is fairly horrible, but splitting this up and merging it via all the different subsystems would have been extremely painful. Instead, we've got all the relevant Acks in place and I've not seen anything other than trivial (Kconfig) conflicts in -next (for completeness, I've included my resolution below). Nearly half of the insertions fall under Documentation/. So, we'll see how this goes. Right now, it all depends on EXPERT and I fully expect people to use FDT by default for the immediate future" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (31 commits) ARM64 / ACPI: make acpi_map_gic_cpu_interface() as void function ARM64 / ACPI: Ignore the return error value of acpi_map_gic_cpu_interface() ARM64 / ACPI: fix usage of acpi_map_gic_cpu_interface ARM64: kernel: acpi: honour acpi=force command line parameter ARM64: kernel: acpi: refactor ACPI tables init and checks ARM64: kernel: psci: let ACPI probe PSCI version ARM64: kernel: psci: factor out probe function ACPI: move arm64 GSI IRQ model to generic GSI IRQ layer ARM64 / ACPI: Don't unflatten device tree if acpi=force is passed ARM64 / ACPI: additions of ACPI documentation for arm64 Documentation: ACPI for ARM64 ARM64 / ACPI: Enable ARM64 in Kconfig XEN / ACPI: Make XEN ACPI depend on X86 ARM64 / ACPI: Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64 clocksource / arch_timer: Parse GTDT to initialize arch timer irqchip: Add GICv2 specific ACPI boot support ARM64 / ACPI: Introduce ACPI_IRQ_MODEL_GIC and register device's gsi ACPI / processor: Make it possible to get CPU hardware ID via GICC ACPI / processor: Introduce phys_cpuid_t for CPU hardware ID ARM64 / ACPI: Parse MADT for SMP initialization ...

2015-04-24x86: fix special __probe_kernel_write() tail zeroing caseLinus Torvalds1-1/+1
Commit cae2a173fe94 ("x86: clean up/fix 'copy_in_user()' tail zeroing") fixed the failure case tail zeroing of one special case of the x86-64 generic user-copy routine, namely when used for the user-to-user case ("copy_in_user()"). But in the process it broke an even more unusual case: using the user copy routine for kernel-to-kernel copying. Now, normally kernel-kernel copies are obviously done using memcpy(), but we have a couple of special cases when we use the user-copy functions. One is when we pass a kernel buffer to a regular user-buffer routine, using set_fs(KERNEL_DS). That's a "normal" case, and continued to work fine, because it never takes any faults (with the possible exception of a silent and successful vmalloc fault). But Jan Beulich pointed out another, very unusual, special case: when we use the user-copy routines not because it's a path that expects a user pointer, but for a couple of ftrace/kgdb cases that want to do a kernel copy, but do so using "unsafe" buffers, and use the user-copy routine to gracefully handle faults. IOW, for probe_kernel_write(). And that broke for the case of a faulting kernel destination, because we saw the kernel destination and wanted to try to clear the tail of the buffer. Which doesn't work, since that's what faults. This only triggers for things like kgdb and ftrace users (eg trying setting a breakpoint on read-only memory), but it's definitely a bug. The fix is to not compare against the kernel address start (TASK_SIZE), but instead use the same limits "access_ok()" uses.

2015-04-24crypto: x86/sha512_ssse3 - fixup for asm function prototype changeArd Biesheuvel1-1/+1
Patch e68410ebf626 ("crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3 implementation to base layer") changed the prototypes of the core asm SHA-512 implementations so that they are compatible with the prototype used by the base layer. However, in one instance, the register that was used for passing the input buffer was reused as a scratch register later on in the code, and since the input buffer param changed places with the digest param -which needs to be written back before the function returns- this resulted in the scratch register to be dereferenced in a memory write operation, causing a GPF. Fix this by changing the scratch register to use the same register as the input buffer param again.
