The arm-cci code uses device tree helpers for initialization that don't work on kernels built without CONFIG_OF. Further, it contains an inline assembly in cci_enable_port_for_self() that uses ARMv7 instructions and fails to build when targetting other ARM instruction set versions. This works around both issues by limiting the scope of the Kconfig symbol to platforms that can actually build this driver cleanly. Signed-off-by:

The dynamic relocation that the keystone platform performs only works if we can pick the phys offset at boot time. It's possible that there is another solution for this, but this is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT are not portable across platforms, and I see no reason why anyone would run a kernel without ARM_PATCH_PHYS_VIRT on keystone. Signed-off-by:

Commit d941f86f ("ARM: l2c: AM43x: add L2 cache support") enabled the L2 cache support for the am43xx SoC, but caused a build regression when the driver for that cache controller is disabled: arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early': :(.init.text+0xb20): undefined reference to `omap_l2_cache_init' This did not happen for OMAP4, which has the same call, but enables the l2x0 driver unconditionally. We could do the same thing for am43xx, but it seems better to allow turning it off and make the code work in either case. This adds an inline wrapper for omap_l2_cache_init for the disabled case, and removes the 'select' from OMAP4 so it becomes a user visible option. Signed-off-by:

Pull part two of ARM SoC updates from Arnd Bergmann: "This is a small follow-up to the larger ARM SoC updates merged last week, almost entirely for the keystone platform. The main change here is to use the new dma-ranges parsing code that came in through Russell's ARM tree. This allows the keystone platform to do cache-coherent DMA and to finally support all the available physical memory when LPAE is enabled. Aside from this, the keystone reset driver has been rewritten, and there is a small bug fix to allow building the orion5x platform again" * tag 'soc2-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: keystone: Drop use of meminfo since its not available anymore ARM: orion5x: fix mvebu_mbus_dt_init call ARM: configs: keystone: enable reset driver support ARM: dts: keystone: update reset node to work with reset driver ARM: keystone: remove redundant reset stuff ARM: keystone: Update the dma offset for non-dt platform devices ARM: keystone: Switch over to coherent memory address space ARM: configs: keystone: add MTD_SPI_NOR (new dependency for M25P80) ARM: configs: keystone: drop CONFIG_COMMON_CLK_DEBUG

Pull powerpc updates from Ben Herrenschmidt: "Here is the bulk of the powerpc changes for this merge window. It got a bit delayed in part because I wasn't paying attention, and in part because I discovered I had a core PCI change without a PCI maintainer ack in it. Bjorn eventually agreed it was ok to merge it though we'll probably improve it later and I didn't want to rebase to add his ack. There is going to be a bit more next week, essentially fixes that I still want to sort through and test. The biggest item this time is the support to build the ppc64 LE kernel with our new v2 ABI. We previously supported v2 userspace but the kernel itself was a tougher nut to crack. This is now sorted mostly thanks to Anton and Rusty. We also have a fairly big series from Cedric that add support for 64-bit LE zImage boot wrapper. This was made harder by the fact that traditionally our zImage wrapper was always 32-bit, but our new LE toolchains don't really support 32-bit anymore (it's somewhat there but not really "supported") so we didn't want to rely on it. This meant more churn that just endian fixes. This brings some more LE bits as well, such as the ability to run in LE mode without a hypervisor (ie. under OPAL firmware) by doing the right OPAL call to reinitialize the CPU to take HV interrupts in the right mode and the usual pile of endian fixes. There's another series from Gavin adding EEH improvements (one day we *will* have a release with less than 20 EEH patches, I promise!). Another highlight is the support for the "Split core" functionality on P8 by Michael. This allows a P8 core to be split into "sub cores" of 4 threads which allows the subcores to run different guests under KVM (the HW still doesn't support a partition per thread). And then the usual misc bits and fixes ..." [ Further delayed by gmail deciding that BenH is a dirty spammer.

This is a third attempt to enable these buttons. The new variable being commit 997daa1b (i.e. hp-wmi: detect "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query method respond with a dummy value, in this case 4. Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries. Signed-off-by:

Remove the code for initializing time if this is first boot. The code for detecting first boot uses undocumented field RTC_TCON in RTC_UDR_CON register. According to S5M8767's datasheet this field is reserved. On S2MPS14 it is not documented at all. On device first boot the registers will be initialized with reset value (2000-01-01 00:00:00). The code might work on S5M8763 but still this does not look like a task for RTC driver. Signed-off-by:

When o2net-accept-one() rejects an illegal connection, it terminates the loop picking up the remaining queued connections. This fix will continue accepting connections till the queue is emtpy. Addresses Orabug 17489469. Signed-off-by:

Right now when people try to report issues in the kernel they send stack dumps to eachother, which looks something like this: [ 6.906437] [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20 [ 6.907121] [<ffffffff84388ce8>] dump_stack+0x52/0x7f [ 6.907640] [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110 [ 6.908281] [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0 [ 6.908870] [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22 [ 6.909480] [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0 [...] However, most of the text you get is pure garbage. The only useful thing above is the function name. Due to the amount of different kernel code versions and various configurations being used, the kernel address and the offset into the function are not really helpful in determining where the problem actually occured. Too often the result of someone looking at a stack dump is asking the person who sent it for a translation for one or more 'addr2line' translations. Which slows down the entire process of debugging the issue (and really annoying). The decode_stacktrace script is an attempt to make the output more useful and easy to work with by translating all kernel addresses in the stack dump into line numbers. Which means that the stack dump would look like this: [ 635.148361] dump_stack (lib/dump_stack.c:52) [ 635.149127] warn_slowpath_common (kernel/panic.c:418) [ 635.150214] warn_slowpath_null (kernel/panic.c:453) [ 635.151031] _oalloc_pages_slowpath+0x6a/0x7d0 [ 635.152171] ? zone_watermark_ok (mm/page_alloc.c:1728) [ 635.152988] ? get_page_from_freelist (mm/page_alloc.c:1939) [ 635.154766] __alloc_pages_nodemask (mm/page_alloc.c:2766) It's pretty obvious why this is better than the previous stack dump before. Usage is pretty simple: ./decode_stacktrace.sh [vmlinux] [base path] Where vmlinux is the vmlinux to extract line numbers from and base path is the path that points to the root of the build tree, for example: ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log The stack trace should be piped through it (I, for example, just pipe the output of the serial console of my KVM test box through it).

The kernel has no concept of capabilities with respect to inodes; inodes exist independently of namespaces. For example, inode_capable(inode, CAP_LINUX_IMMUTABLE) would be nonsense. This patch changes inode_capable to check for uid and gid mappings and renames it to capable_wrt_inode_uidgid, which should make it more obvious what it does. Fixes CVE-2014-4014.
