* Documentation: fix blackfin gptimers-example build errorsRandy Dunlap2015-01-281-0/+2
| | | | | | | | | | | | | | | | | | | | Don't build the blackfin gptimers-example module when BFIN_GPTIMERS is not enabled. Allow the build when BFIN_GPTIMERS is =y or =m. I believe that this patch fixes these build errors, but I don't have a build environment to test this. ERROR: "disable_gptimers" [Documentation/blackfin/gptimers-example.ko] undefined!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some clock modules on the A31 use PLL6x2 as one of their inputs. This patch changes the PLL6 implementation for A31 to a divs clock, i.e. clock with multiple outputs that have different dividers. The first output will be the normal PLL6 output, and the second will be PLL6x2. This patch fixes the PLL6 N factor in the clock driver, and removes any /2 dividers in the PLL6 factors clock part. The N factor counts from 1 to 32, mapping to values 0 to 31, as shown in the A31 manual. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

Also there is a bus clock for a ARM CCI400 module. As far as I can tell, the GT bus and CCI400 bus clock must be protected. This patch adds driver support for peripheral related PLLs and bus clocks on the A80. The GT and CCI400 clocks are added as well as these 2 along with the PLLs they are clocked from must not be disabled.

I did something like: bndcfgu |= bnd_dir | BNDCFGU_ENABLE; xrstor(); printf("xrstor done"); // #BR bounds exception here prctl(MPX_ENABLE_MANAGEMENT); and then compiled the app with "-fcheck-pointer-bounds -mmpx" to enable MPX instrumentation. The problem is that there is MPX instrumentation inserted in to the area of the printf(). The kernel gets a bounds exception and since management isn't yet enabled, it SIGSEGV's. Add a bit to the documentation to explain a way around this and where apps need to be careful.

There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem. An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we take it through the powerpc tree. A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit maintainers. A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file, so that tools can use it. Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and the patch to add __force to get_user() so we can use bitwise types" * tag 'powerpc-3.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux: powerpc/powernv: Ignore smt-enabled on Power8 and later powerpc/uaccess: Allow get_user() with bitwise types powerpc/powernv: Expose OPAL firmware symbol map powernv/powerpc: Add winkle support for offline cpus powernv/cpuidle: Redesign idle states management powerpc/powernv: Enable Offline CPUs to enter deep idle states powerpc/powernv: Switch off MMU before entering nap/sleep/rvwinkle mode i2c: Driver to expose PowerNV platform i2c busses powerpc: add little endian flag to syscall_get_arch() power/perf/hv-24x7: Use kmem_cache_free() instead of kfree powerpc/perf/hv-24x7: Use per-cpu page buffer cxl: Unmap MMIO regions when detaching a context cxl: Add timeout to process element commands cxl: Change contexts_lock to a mutex to fix sleep while atomic bug powerpc: Secondary CPUs must set cpu_callin_map after setting active and online

Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.
