2015-01-08drm/radeon: fix VM flush on cayman/aruba (v3)Alex Deucher
We need to wait for the GPUVM flush to complete. There was some confusion as to how this mechanism was supposed to work. The operation is not atomic. For GPU initiated invalidations you need to read back a VM register to introduce enough latency for the update to complete. v2: drop gart changes v3: just read back rather than polling Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2015-01-08perf hists: Fix children sort key behaviorNamhyung Kim
When perf report --children resorts output fields, it tries to put caller above the callee. But this was only meaningful for a same thread and doing this requires callchain enabled. So fix its check before comparing the callchain depth. This also changes the hist accumulation tests: In test 3, xmalloc in bash thread should be above than other perf threads due to alphabetical order of comm string. Also it's under page_fault in bash thread since alphabetical order of dso name. The sys_perf_event_open in perf thread is put on the last line since it's self overhead is 0. In test 4, the sys_perf_event_open is put above other perf entries that have same children overhead since its callchain depth is smaller.

2015-01-08x86/xen: avoid freeing static 'name' when kasprintf() failsVitaly Kuznetsov
In case kasprintf() fails in xen_setup_timer() we assign name to the static string "<timer kasprintf failed>". We, however, don't check that fact before issuing kfree() in xen_teardown_timer(), kernel is supposed to crash with 'kernel BUG at mm/slub.c:3341!'

2015-01-08arm64/efi: add missing call to early_ioremap_reset()Ard Biesheuvel
The early ioremap support introduced by patch bf4b558eba92 ("arm64: add early_ioremap support") failed to add a call to early_ioremap_reset() at an appropriate time. Without this call, invocations of early_ioremap etc. that are done too late will go unnoticed and may cause corruption. This is exactly what happened when the first user of this feature was added in patch f84d02755f5a ("arm64: add EFI runtime services"). The early mapping of the EFI memory map is unmapped during an early initcall, at which time the early ioremap support is long gone. Fix by adding the missing call to early_ioremap_reset() to setup_arch(), and move the offending early_memunmap() to right after the point where the early mapping of the EFI memory map is last used.

2015-01-08ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instancesGeert Uytterhoeven
The sh73a0 INTC can't mask interrupts properly most likely due to a hardware bug. Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from. This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>.

Now local variables kernel_x_start and kernel_x_end defined using 'unsigned long' type which is wrong because they represent physical memory range and will be calculated wrongly if LPAE is enabled. As result, all following code in map_lowmem() will not work correctly. For example, Keystone 2 boot is broken because kernel_x_start == 0x0000 0000 kernel_x_end == 0x0080 0000 instead of kernel_x_start == 0x0000 0008 0000 0000 kernel_x_end == 0x0000 0008 0080 0000 and as result whole low memory will be mapped with MT_MEMORY_RW permissions by code (start > kernel_x_end): } else if (start >= kernel_x_end) { map.pfn = __phys_to_pfn(start); map.virtual = __phys_to_virt(start); map.length = end - start; map.type = MT_MEMORY_RW; create_mapping(&map); } Hence, fix it by using phys_addr_t type for variables kernel_x_start and kernel_x_end.

2015-01-07ARM: 8249/1: mm: dump: don't skip regionsMark Rutland
Currently the arm page table dumping code starts dumping page tables from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries related to userspace as the swapper_pg_dir does not contain such entries, and results in a couple of unfortuante side effects. Firstly, any kernel mappings which might exist below USER_PGTABLES_CEILING will not be accounted in the dump output. This masks any entries erroneously created below this address. Secondly, if the final page table entry walked is part of a valid mapping the page table dumping code will not log the region this entry is part of, as the final note_page call in walk_pgd will trigger an early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on contemporary systems as they typically don't have enough RAM to extend the linear mapping right to the end of the address space. Due to the way addr is constructed in the walk_* functions, it can never be less than USER_PGTABLES_CEILING when walking the page tables, so it is not necessary to avoid dereferencing invalid table addresses. The existing checks for st->current_prot and st->marker[1].start_address are sufficient to ensure we will not print and/or dereference garbage when trying to log information. This patch removes both problematic uses of USER_PGTABLES_CEILING from the arm page table dumping code, preventing both of these issues. We will now report any low mappings, and the final note_page call will not return early, ensuring all regions are logged.

2015-01-07rpc: fix xdr_truncate_encode to handle buffer ending on page boundaryJ. Bruce Fields
A struct xdr_stream at a page boundary might point to the end of one page or the beginning of the next, but xdr_truncate_encode isn't prepared to handle the former. This can cause corruption of NFSv4 READDIR replies in the case that a readdir entry that would have exceeded the client's dircount/maxcount limit would have ended exactly on a 4k page boundary. You're more likely to hit this case on large directories. Other xdr_truncate_encode callers are probably also affected.

2015-01-07arm64: sanity checks: add missing AArch32 registersMark Rutland
We don't currently check a number of registers exposed to AArch32 guests (MVFR{0,1,2}_EL1 and ID_DFR0_EL1), despite the fact these describe AArch32 feature support exposed to userspace and KVM guests similarly to AArch64 registers which we do check. We do not expect these registers to vary across a set of CPUs. This patch adds said registers to the cpuinfo framework and sanity checks. No sanity check failures have been observed on a current ARMv8 big.LITTLE platform (Juno). Cc: Catalin Marinas <catalin.marinas@arm.com> Reported-by: Suzuki K.

2015-01-07arm64: Correct __NR_compat_syscalls for bpfMark Rutland
Commit 97b56be10352a70c (arm64: compat: Enable bpf syscall) made the usual mistake of forgetting to update __NR_compat_syscalls. Due to this, when el0_sync_compat calls el0_svc_naked, the test against sc_nr (__NR_compat_syscalls) will fail, and we'll call ni_sys, returning -ENOSYS to userspace. This patch bumps __NR_compat_syscalls appropriately, enabling the use of the bpf syscall from compat tasks. Due to the reorganisation of unistd{,32}.h as part of commit f3e5c847ec3d12b4 (arm64: Add __NR_* definitions for compat syscalls) it is not currently possible to include both headers and sanity-check the value of __NR_compat_syscalls at build-time to prevent this from happening again. Additional rework is required to make such niceties a possibility.

2015-01-07pinctrl: st: avoid multiple mutex lockFrancesco VIRLINZI
Using the sysfs inteface to inspect the pins configuration the system can walk around a path which acquires the same mutex twice. On STiH407 platform, for example : cat /sys/kernel/debug/pinctrl/920f080.pin-controller-front0/pinconf-pins hangs the kernel and never returns. With this patch the mutex is temporary freed.

2015-01-07gpio: dln2: fix issue when an IRQ is unmasked then enabledOctavian Purdila
As noticed during suspend/resume operations, the IRQ can be unmasked then disabled in suspend and eventually enabled in resume, but without being unmasked. The current implementation does not take into account interactions between mask/unmask and enable/disable interrupts, and thus in the above scenarios the IRQs remain unactive. To fix this we removed the enable/disable operations as they fallback to mask/unmask anyway. We also remove the pending bitmaks as it is already done in irq_data (i.e. IRQS_PENDING).

As has been discussed in the thread starting with https://lkml.kernel.org/g/549748e9.d+SiJzqu50f1r4lSAL043YSc@arcor.de Sierra Wireless MC73xx devices with USB VID/PID 0x1199:0x68c0 require the option_send_setup() code to be used on the USB interface for the AT port to make unsolicited response codes work correctly. Move these devices from the qcserial driver where they have been added by commit 70a3615fc07c2330ed7c1e922f3c44f4a67c0762 ("usb: qcserial: add Sierra Wireless MC73xx") to the option driver and add a MC73xx-specific blacklist to ensure that 1. the sendsetup code is not used for the DIAG/DM and NMEA interfaces 2. the option driver does not attach to the QMI/network interfaces Signed-off-by: Reinhard Speyerer <rspmn@arcor.de> Cc: stable <stable@vger.kernel.org> Signed-off-by: Johan Hovold <johan@kernel.org>
