2015-05-12MIPS: Fix a preemption issue with thread's FPU defaultsMaciej W. Rozycki
Fix "BUG: using smp_processor_id() in preemptible" reported in accesses to thread's FPU defaults: the value to initialise FSCR to at program startup, the FCSR r/w mask and the contents of FIR in full FPU emulation, removing a regression introduced with 9b26616c [MIPS: Respect the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR feature flags for full emulation]. Use `boot_cpu_data' to obtain the data from, following the approach that `cpu_has_*' macros take and avoiding the call to `smp_processor_id' made in the reference to `current_cpu_data'. The contents of FSCR have to be consistent across processors in an SMP system, the settings there must not change as a thread is migrated across processors. And the contents of FIR are guaranteed to be consistent in FPU emulation, by definition. Signed-off-by: Maciej W.

2015-05-12parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards ↵Helge Deller
architectures On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y, currently parisc and metag only) stack randomization sometimes leads to crashes when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB by default if not defined in arch-specific headers). The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the additional space needed for the stack randomization (as defined by the value of STACK_RND_MASK) was not taken into account yet and as such, when the stack randomization code added a random offset to the stack start, the stack effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK) which then sometimes leads to out-of-stack situations and crashes. This patch fixes it by adding the maximum possible amount of memory (based on STACK_RND_MASK) which theoretically could be added by the stack randomization code to the initial stack size. That way, the user-defined stack size is always guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK). This bug is currently not visible on the metag architecture, because on metag STACK_RND_MASK is defined to 0 which effectively disables stack randomization. The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP" section, so it does not affect other platformws beside those where the stack grows upwards (parisc and metag).

2015-05-12MIPS: fix FP mode selection in lieu of .MIPS.abiflags dataPaul Burton
Commit 46490b572544 ("MIPS: kernel: elf: Improve the overall ABI and FPU mode checks") reworked the ELF FP ABI mode selection logic, but when CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries which have no PT_MIPS_ABIFLAGS program header & associated .MIPS.abiflags section. A default mode is selected based upon whether the ELF contains MIPS32 or MIPS64 code, but that selection is made in arch_elf_pt_proc. arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is found. If one is not found then arch_elf_pt_proc is never called, and no default overall_fp_mode value is selected. When arch_check_elf is called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both prog_req & interp_req being set to none_req. none_req matches none of the conditions for mode selection at the end of arch_check_elf, so overall_fp_mode is left untouched. Finally once mips_set_personality_fp is called the BUG() in the default case is then hit & the kernel likely panics. Fix this by moving the selection of a default overall mode to the start of arch_check_elf, which runs once per ELF executed regardless of whether it has a PT_MIPS_ABIFLAGS program header.

2015-05-12arm64: perf: fix memory leak when probing PMU PPIsWill Deacon
Commit d795ef9aa831 ("arm64: perf: don't warn about missing interrupt-affinity property for PPIs") added a check for PPIs so that we avoid parsing the interrupt-affinity property for these naturally affine interrupts. Unfortunately, this check can trigger an early (successful) return and we will leak the irqs array. This patch fixes the issue by reordering the code so that the check is performed before any independent allocation.

2015-05-12phy: fix Kconfig dependenciesFelipe Balbi
DM816x PHY uses usb_phy_* methods and because of that, it must select USB_PHY, however, because the drivers in question (DM816x, TWL4030 and OMAP_USB2) sit outside of drivers/usb/ directory, meaning they can be built even if USB_SUPPORT=n. This patches fixes the dependencies by adding USB_SUPPORT as a dependency and making all drivers select USB_PHY (which cannot be selected through menuconfig). Note that this fixes some linking breakages when building with randconfig.

Emulex developers' email addresses are now "@avagotech" instead of "@emulex". I'm also replacing Subbu with Padmanabh and Sriharsha in the maintainers list. The driver's heading was outdated and did not include some of the chip types (BE3, Lancer and Skyhawk) that the driver has been supporting for a longtime. I've updated this too.
