2016-02-01ARM64: tegra: Add chosen node for tegra132 norrinJon Hunter
The NVIDIA bootloader, nvtboot, expects the "chosen" node to be present in the device-tree blob and if it is not then it fails to boot the kernel. Add the chosen node so we can boot the kernel on Tegra132 Norrin with the nvtboot bootloader.

2016-02-01arm64: dts: Add missing DMA Abort interrupt to JunoRobin Murphy
The DMA-330 has an "irq_abort" interrupt line on which it signals faults separately from the "irq[n:0]" channel interrupts. On Juno, this is wired up to SPI 92; add it to the DT so that DMAC faults are correctly reported for the driver to reset the thing, rather than leaving it locked up and waiting to time out.

2016-01-29x86/mm/pat: Avoid truncation when converting cpa->numpages to addressMatt Fleming
There are a couple of nasty truncation bugs lurking in the pageattr code that can be triggered when mapping EFI regions, e.g. when we pass a cpa->pgd pointer. Because cpa->numpages is a 32-bit value, shifting left by PAGE_SHIFT will truncate the resultant address to 32-bits. Viorel-Cătălin managed to trigger this bug on his Dell machine that provides a ~5GB EFI region which requires 1236992 pages to be mapped. When calling populate_pud() the end of the region gets calculated incorrectly in the following buggy expression, end = start + (cpa->numpages << PAGE_SHIFT); And only 188416 pages are mapped. Next, populate_pud() gets invoked for a second time because of the loop in __change_page_attr_set_clr(), only this time no pages get mapped because shifting the remaining number of pages (1048576) by PAGE_SHIFT is zero. At which point the loop in __change_page_attr_set_clr() spins forever because we fail to map progress. Hitting this bug depends very much on the virtual address we pick to map the large region at and how many pages we map on the initial run through the loop. This explains why this issue was only recently hit with the introduction of commit a5caa209ba9c ("x86/efi: Fix boot crash by mapping EFI memmap entries bottom-up at runtime, instead of top-down") It's interesting to note that safe uses of cpa->numpages do exist in the pageattr code. If instead of shifting ->numpages we multiply by PAGE_SIZE, no truncation occurs because PAGE_SIZE is a UL value, and so the result is unsigned long. To avoid surprises when users try to convert very large cpa->numpages values to addresses, change the data type from 'int' to 'unsigned long', thereby making it suitable for shifting by PAGE_SHIFT without any type casting. The alternative would be to make liberal use of casting, but that is far more likely to cause problems in the future when someone adds more code and fails to cast properly; this bug was difficult enough to track down in the first place.

2016-01-29perf/x86: Fix uninitialized value usagePeter Zijlstra
When calling intel_alt_er() with .idx != EXTRA_REG_RSP_* we will not initialize alt_idx and then use this uninitialized value to index an array. When that is not fatal, it can result in an infinite loop in its caller __intel_shared_reg_get_constraints(), with IRQs disabled. Alternative error modes are random memory corruption due to the cpuc->shared_regs->regs[] array overrun, which manifest in either get_constraints or put_constraints doing weird stuff. Only took 6 hours of painful debugging to find this. Neither GCC nor Smatch warnings flagged this bug.

2016-01-28powerpc/perf: Remove PPMU_HAS_SSLOT flag for Power8Madhavan Srinivasan
Commit 7a7868326d77 ("powerpc/perf: Add an explict flag indicating presence of SLOT field") introduced the PPMU_HAS_SSLOT flag to remove the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not set. That commit's changelog also mentions that Power8 does not support MMCRA[SLOT]. However when the Power8 PMU support was merged, it errnoeously included the PPMU_HAS_SSLOT flag. So remove PPMU_HAS_SSLOT from the Power8 flags. mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39 (IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with the high bits of the Threshold Event Counter Mantissa. I am not aware of any published events which use the threshold counting mechanism, which would cause the mantissa bits to be set. So in practice this bug is unlikely to trigger.

The interrupt-parent property is not needed as it is inherited from the parent bus and in the case of the CAAM node actively points to the wrong interrupt controller (GIC instead of GPC). This leads to the CAAM IRQs not getting unmasked at the GPC level, leaving them unable to wake the CPU from wait mode, potentially impacting performance of the CAAM unit when CPUidle is enabled.

2016-01-27ARM: dts: at91: sama5d2 xplained: add phy address and IRQ for macb0Nicolas Ferre
After 57a38effa598 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091) the macb0 interface has difficulties to come back from power saving mode if address not explicitly set up. As the micrel phy on the board is actually configured to show up at address 1 we use this explicitly. Adding the phy node and its real address fixes the issue. The phy IRQ and associated pinmux node is also added.

2016-01-27powerpc/eeh: Fix PE location codeGavin Shan
In eeh_pe_loc_get(), the PE location code is retrieved from the "ibm,loc-code" property of the device node for the bridge of the PE's primary bus. It's not correct because the property indicates the parent PE's location code. This reads the correct PE location code from "ibm,io-base-loc-code" or "ibm,slot-location-code" property of PE parent bus's device node.

2016-01-26ARM: 8500/1: fix atags_to_fdt with stack-protector-strongKees Cook
Building with CONFIG_CC_STACKPROTECTOR_STRONG triggers protection code generation under CONFIG_ARM_ATAG_DTB_COMPAT but this is too early for being able to use any of the stack_chk code. Explicitly disable it for only the atags_to_fdt bits.

2016-01-26x86/mm: Fix types used in pgprot cacheability flags translationsJan Beulich
For PAE kernels "unsigned long" is not suitable to hold page protection flags, since _PAGE_NX doesn't fit there. This is the reason for quite a few W+X pages getting reported as insecure during boot (observed namely for the entire initrd range).

2016-01-26arm64: mm: avoid calling apply_to_page_range on empty rangeMika Penttilä
Calling apply_to_page_range with an empty range results in a BUG_ON from the core code. This can be triggered by trying to load the st_drv module with CONFIG_DEBUG_SET_MODULE_RONX enabled: kernel BUG at mm/memory.c:1874! Internal error: Oops - BUG: 0 [#1] PREEMPT SMP Modules linked in: CPU: 3 PID: 1764 Comm: insmod Not tainted 4.5.0-rc1+ #2 Hardware name: ARM Juno development board (r0) (DT) task: ffffffc9763b8000 ti: ffffffc975af8000 task.ti: ffffffc975af8000 PC is at apply_to_page_range+0x2cc/0x2d0 LR is at change_memory_common+0x80/0x108 This patch fixes the issue by making change_memory_common (called by the set_memory_* functions) a NOP when numpages == 0, therefore avoiding the erroneous call to apply_to_page_range and bringing us into line with x86 and s390.
