Randomization of PIE load address is hard coded in binfmt_elf.c for X86 and ARM. Create a new Kconfig variable (CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead. Thus architecture specific policy is pushed out of the generic binfmt_elf.c and into the architecture Kconfig files. X86 and ARM Kconfigs are modified to select the new variable so there is no change in behavior. A follow on patch will select it for MIPS too.

Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP - there's no user of early_node_map[] left. Kill early_node_map[] and replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP. Also, relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h as page_alloc.c would no longer host an alternative implementation. This change is ultimately one to one mapping and shouldn't cause any observable difference; however, after the recent changes, there are some functions which now would fit memblock.c better than page_alloc.c and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK doesn't make much sense on some of them. Further cleanups for functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice. -v2: Fix compile bug introduced by mis-spelling CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in mmzone.h.

This new driver replaces the old PCEngines Alix 2/3 LED driver with a new driver that controls the LEDs through the leds-gpio driver. The old driver accessed GPIOs directly, which created a conflict and prevented also loading the cs5535-gpio driver to read other GPIOs on the Alix board. With this new driver, we hook into leds-gpio which in turn uses GPIO to control the LEDs and therefore it's possible to control both the LEDs and access onboard GPIOs Driver is moved to platform/geode as requested by Grant and any other geode initialisation modules should move here also This driver is inspired by leds-net5501.c by Alessandro Zummo. Ideally, leds-net5501.c should also be moved to platform/geode. Additionally the driver relies on parts of the patch: 7f131cf3 ("leds: leds-alix2c - take port address from MSR) by Daniel Mack to perform detection of the Alix board.

The automatic increase of the min_delta_ns of a clockevents device should be done in the clockevents code as the minimum delay is an attribute of the clockevents device. In addition not all architectures want the automatic adjustment, on a massively virtualized system it can happen that the programming of a clock event fails several times in a row because the virtual cpu has been rescheduled quickly enough. In that case the minimum delay will erroneously be increased with no way back. The new config symbol GENERIC_CLOCKEVENTS_MIN_ADJUST is used to enable the automatic adjustment. The config option is selected only for x86.

cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

Architectural inlines to get random ints and longs using the RDRAND instruction. Intel has introduced a new RDRAND instruction, a Digital Random Number Generator (DRNG), which is functionally an high bandwidth entropy source, cryptographic whitener, and integrity monitor all built into hardware. This enables RDRAND to be used directly, bypassing the kernel random number pool. For technical documentation, see: http://software.intel.com/en-us/articles/download-the-latest-bull-mountain-software-implementation-guide/ In this patch, this is *only* used for the nonblocking random number pool. RDRAND is a nonblocking source, similar to our /dev/urandom, and is therefore not a direct replacement for /dev/random. The architectural hooks presented in the previous patch only feed the kernel internal users, which only use the nonblocking pool, and so this is not a problem. Since this instruction is available in userspace, there is no reason to have a /dev/hw_rng device driver for the purpose of feeding rngd. This is especially so since RDRAND is a nonblocking source, and needs additional whitening and reduction (see the above technical documentation for details) in order to be of "pure entropy source" quality. The CONFIG_EXPERT compile-time option can be used to disable this use of RDRAND. Signed-off-by: NH.

This patch makes update_rq_clock() aware of steal time. The mechanism of operation is not different from irq_time, and follows the same principles. This lives in a CONFIG option itself, and can be compiled out independently of the rest of steal time reporting. The effect of disabling it is that the scheduler will still report steal time (that cannot be disabled), but won't use this information for cpu power adjustments. Everytime update_rq_clock_task() is invoked, we query information about how much time was stolen since last call, and feed it into sched_rt_avg_update(). Although steal time reporting in account_process_tick() keeps track of the last time we read the steal clock, in prev_steal_time, this patch do it independently using another field, prev_steal_time_rq. This is because otherwise, information about time accounted in update_process_tick() would never reach us in update_rq_clock().

Commit 2706a0bf ("x86, NUMA: Enable CONFIG_AMD_NUMA on 32bit too") enabled AMD NUMA for 32bit too. Unfortunately, SPARSEMEM on 32bit had rather coarse (512MiB) addr->node mapping granularity due to lack of space in page->flags. This led to boot failure on certain AMD NUMA machines which had 128MiB alignment on nodes. Patches to properly detect this condition and reject NUMA configuration are posted[1] but deemed too pervasive for merge at this point (-rc6). Disable AMD NUMA for 32bit for now and re-enable once the detection logic is merged.

The APB timers are an IP block from Synopsys (DesignWare APB timers) and are also found in other systems including ARM SoC's. This patch adds functions for creating clock_event_devices and clocksources from APB timers but does not do the resource allocation. This is handled in a higher layer to allow the timers to be created from multiple methods such as platform_devices. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.

This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Note: to move intel-iommu.c, the declaration of pci_find_upstream_pcie_bridge() has to move from drivers/pci/pci.h to include/linux/pci.h. This is handled in this patch, too. As suggested, also drop DMAR's EXPERIMENTAL tag while we're at it. Compile-tested on x86_64. Signed-off-by: NOhad Ben-Cohen <ohad@wizery.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

Create a dedicated folder for iommu drivers, and move the base iommu implementation over there. Grouping the various iommu drivers in a single location will help finding similar problems shared by different platforms, so they could be solved once, in the iommu framework, instead of solved differently (or duplicated) in each driver.

Lenghty lists of the kind "depends on ARCH1 || ARCH2 ... || ARCH123" are usually either wrong or too coarse grained. Or plain an ugly sin.
