2015-05-12net: phy: micrel: Fix regression in kszphy_probeNiklas Cassel
Don't do clock-mode-select if clk == NULL, since when building without CONFIG_HAVE_CLK, clk_get returns NULL and clk_get_rate returns 0. Doing clock-mode-select in this cause causes kszphy_probe to return -EINVAL and thus prevents the device from being probed. The original code (before regression) would return 0 when building without CONFIG_HAVE_CLK.

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.

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).

2015-05-12drm/edid: Add CEA modes before inferred modesVille Syrjälä
Currently we're adding CEA modes after the inferred modes, which means we might get multiple modes that are very close to each other, but slightly different, which seems a bit silly. That's because duplicate mode check that occurs when adding inferred modes would not consider CEA modes as potential duplicates. Reverse the order so that CEA modes get added before inferred modes, and are thus considered potential duplicates. Or as ajax put it on irc: "< ajax> the point of the "pick a timing formula" heuristic was to generate something the sink could _likely_ sink. if it tells us timings it can sink explicitly then second-guessing seems dumb."

2015-05-12RDMA/core: Fix for parsing netlink string attributeTatyana Nikolova
The string iwpm_ulib_name is recorded in a nlmsg as a netlink attribute. Without this fix parsing of the nlmsg by the userspace port mapper service fails because of unknown attribute length, causing the port mapper service not to register the client, which has sent the nlmsg.

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.

2015-05-12ARM64: juno: add sp810 support and fix sp804 clock frequencySudeep Holla
The clock generator in IOFPGA generates the two source clocks: 32kHz and 1MHz for the SP810 System Controller. The SP810 System Controller selects 32kHz or 1MHz as the sources for TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but the maximum of "refclk" and "timclk" is chosen by the SP810 driver. This patch adds support for SP810 system controller and also fixes the SP804 timer clock frequency. However the SP804 driver needs to be enabled on ARM64 to test this, which requires SP804 driver to be moved out of arch/arm. Fixes: 71f867ec130e ("arm64: Add Juno board device tree.")

2015-05-12drm/prime: Allow internal imports without import_sg_tableTomasz Figa
Currently drm_gem_prime_import() checks if gem_prime_import_sg_table() is implemented in DRM driver ops. However it is not necessary for internal imports (i.e. dma_buf->ops == &drm_gem_prime_dmabuf_ops and obj->dev == dev), which only increment reference count on respective GEM objects. This patch makes the helper check this condition only in case of external imports fo rwhich importing sg table is indeed needed.
