2014-11-05powerpc: Remove ppc64_boot_msgAnton Blanchard
ppc64_boot_msg is meant to be a boot debug aid, but is only used in one spot. Get rid of it, and save ourseleves a couple of lines in the kernel log buffer. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2014-11-05arm64/efi: invert UEFI memory region reservation logicArd Biesheuvel
Instead of reserving the memory regions based on which types we know need to be reserved, consider only regions of the following types as free for general use by the OS: EFI_LOADER_CODE EFI_LOADER_DATA EFI_BOOT_SERVICES_CODE EFI_BOOT_SERVICES_DATA EFI_CONVENTIONAL_MEMORY Note that this also fixes a problem with the original code, which would misidentify a EFI_RUNTIME_SERVICES_DATA region as not reserved if it does not have the EFI_MEMORY_RUNTIME attribute set. However, it is perfectly legal for the firmware not to request a virtual mapping for EFI_RUNTIME_SERVICES_DATA regions that contain configuration tables, in which case the EFI_MEMORY_RUNTIME attribute would not be set.

2014-11-05arm64/efi: set PE/COFF section alignment to 4 KBArd Biesheuvel
Position independent AArch64 code needs to be linked and loaded at the same relative offset from a 4 KB boundary, or adrp/add and adrp/ldr pairs will not work correctly. (This is how PC relative symbol references with a 4 GB reach are emitted) We need to declare this in the PE/COFF header, otherwise the PE/COFF loader may load the Image and invoke the stub at an offset which violates this rule.

2014-11-05arm64/efi: efistub: jump to 'stext' directly, not through the headerArd Biesheuvel
After the EFI stub has done its business, it jumps into the kernel by branching to offset #0 of the loaded Image, which is where it expects to find the header containing a 'branch to stext' instruction. However, the UEFI spec 2.1.1 states the following regarding PE/COFF image loading: "A UEFI image is loaded into memory through the LoadImage() Boot Service. This service loads an image with a PE32+ format into memory. This PE32+ loader is required to load all sections of the PE32+ image into memory." In other words, it is /not/ required to load parts of the image that are not covered by a PE/COFF section, so it may not have loaded the header at the expected offset, as it is not covered by any PE/COFF section. So instead, jump to 'stext' directly, which is at the base of the PE/COFF .text section, by supplying a symbol 'stext_offset' to efi-entry.o which contains the relative offset of stext into the Image. Also replace other open coded calculations of the same value with a reference to 'stext_offset' Acked-by: Mark Rutland <mark.rutland@arm.com> Acked-by: Roy Franz <roy.franz@linaro.org> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>

2014-11-04leds: leds-gpio: Convert gpio_blink_set() to use GPIO descriptorsMika Westerberg
Commit 21f2aae91e902aad ("leds: leds-gpio: Add support for GPIO descriptors") already converted most of the driver to use GPIO descriptors. What is still missing is the platform specific hook gpio_blink_set() and board files which pass legacy GPIO numbers to this driver in platform data. In this patch we handle the former and convert gpio_blink_set() to take GPIO descriptor instead. In order to do this we convert the existing four users to accept GPIO descriptor and translate it to legacy GPIO number in the platform code. This effectively "pushes" legacy GPIO number usage from the driver to platforms. Also add comment to the remaining block describing that it is legacy code path and we are getting rid of it eventually.

2014-11-04x86-64: Use RIP-relative addressing for most per-CPU accessesJan Beulich
Observing that per-CPU data (in the SMP case) is reachable by exploiting 64-bit address wraparound (building on the default kernel load address being at 16Mb), the one byte shorter RIP-relative addressing form can be used for most per-CPU accesses. The one exception are the "stable" reads, where the use of the "P" operand modifier prevents the compiler from using RIP-relative addressing, but is unavoidable due to the use of the "p" constraint (side note: with gcc 4.9.x the intended effect of this isn't being achieved anymore, see gcc bug 63637). With the dependency on the minimum kernel load address, arbitrarily low values for CONFIG_PHYSICAL_START are now no longer possible. A link time assertion is being added, directing to the need to increase that value when it triggers.

2014-11-04x86: mm: Use 2GB memory block size on large-memory x86-64 systemsDaniel J Blueman
On large-memory x86-64 systems of 64GB or more with memory hot-plug enabled, use a 2GB memory block size. Eg with 64GB memory, this reduces the number of directories in /sys/devices/system/memory from 512 to 32, making it more manageable, and reducing the creation time accordingly. This caveat is that the memory can't be offlined (for hotplug or otherwise) with the finer default 128MB granularity, but this is unimportant due to the high memory densities generally used with such large-memory systems, where eg a single DIMM is the order of 16GB.

2014-11-04x86: numachip: Elide self-IPI ICR pollingDaniel J Blueman
The default self-IPI path polls the ICR to delay sending the IPI until there is no IPI in progress. This is redundant on x86-86 APICs, since IPIs are queued. See the AMD64 Architecture Programmer's Manual, vol 2, p525.

Prevent 16-bit APIC IDs being truncated by using correct mask. This fixes booting large systems, where the wrong core would receive the startup and init IPIs, causing hanging.

2014-11-04ARM: sun7i: olinuxino lime: Relicense the device tree under GPLv2/X11Maxime Ripard
The current GPL only licensing on the DTSI makes it very impractical for other software components licensed under another license. In order to make it easier for them to reuse our device trees, relicense our device trees under a GPL/X11 dual-license.

2014-11-04ARM: imx: Fix the removal of CONFIG_SPI optionFabio Estevam
Since 64546e9fe3a5b8c ("ARM: imx_v6_v7_defconfig updates") and commit 0650f855d2e4b0b9 ("ARM: imx_v4_v5_defconfig: Select CONFIG_IMX_WEIM") CONFIG_SPI selection was dropped by savedefconfig for imx_v4_v5_defconfig and imx_v6_v7_defconfig. In order to keep the same behaviour as previous kernel versions and avoid regressions, let's add CONFIG_SPI option back.
