2013-06-24cgroup: clean up find_css_set() and friendsTejun Heo
find_css_set() passes uninitialized on-stack template[] array to find_existing_css_set() which sets the entries for all subsystems. Passing around an uninitialized array is a bit icky and we want to introduce an iterator which only iterates loaded subsystems. Let's initialize it on definition. While at it, also make the following cosmetic cleanups. * Convert to proper /** comments. * Reorder variable declarations. * Replace comment on synchronization with lockdep_assert_held(). This patch doesn't make any functional differences. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
2013-06-24cgroup: remove cgroup->actual_subsys_maskTejun Heo
cgroup curiously has two subsystem masks, ->subsys_mask and ->actual_subsys_mask. The latter only exists because the new target subsys_mask is passed into rebind_subsystems() via @root>subsys_mask. rebind_subsystems() needs to know what the current mask is to decide how to reach the target mask so ->actual_subsys_mask is used as the temp location to remember the current state. Adding a temporary field to a permanent data structure is rather silly and can be misleading. Update rebind_subsystems() to take @added_mask and @removed_mask instead and remove @root->actual_subsys_mask. This patch shouldn't introduce any behavior changes. v2: Comment and description updated as suggested by Li. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
2013-06-24cgroup: prefix global variables with "cgroup_"Tejun Heo

2013-06-24powerpc/pci: Fix boot panic on mpc83xx (regression)Rojhalat Ibrahim
The following commit caused a fatal oops when booting on mpc83xx with a non-express PCI bus (regardless of whether a PCI device is present): commit 50d8f87d2b39313dae9d0a2d9b23d377328f2f7b Author: Rojhalat Ibrahim <imr@rtschenk.de> Date: Mon Apr 8 10:15:28 2013 +0200 powerpc/fsl-pci Make PCIe hotplug work with Freescale PCIe controllers Up to now the PCIe link status on Freescale PCIe controllers was only checked once at boot time.

2013-06-24clk: tegra: fix ifdef for tegra_periph_reset_assert inlineStephen Warren
Commit 7064f6b "clk: tegra: provide tegra_periph_reset_assert alternative" added ifdef'd static inline versions of some functions, but tested ARCH_TEGRA rather than CONFIG_ARCH_TEGRA, thus disabling these function in all cases.

2013-06-24ARM: msm: Migrate to common clock frameworkStephen Boyd
Move the existing clock code in mach-msm to the common clock framework. We lose our capability to set the rate of and enable a clock through debugfs. This is ok though because the debugfs features are mainly used for testing and development of new clock code. To maintain compatibility with the original MSM clock code we make a wrapper for clk_reset() that calls the struct msm_clk specific reset function. This is necessary for the usb and sdcc devices on MSM until a better suited API is made available.

2013-06-24msm_serial: Use devm_clk_get() and properly return errorsStephen Boyd
Clocks are not clk_put() in this driver's error paths during probe. The code that checks for clock errors also fails to properly return the error code from the pclk member if it turns out to be the failing clock, leading to potentially confusing error values if the clk member is not an error pointer. Fix these problems with devm_clk_get() and proper error checking. Removing the clk_put() in msm_serial_remove() also points out that msm_port is unused. Furthermore, msm_port is the wrong type and so the clk_put() would be using the wrong pointer. Replace it with the proper type and call uart_remove_one_port() to do the proper cleanup.

When compiling a MMU kernel with CPU_HAS_ADDRESS_SPACES=n (e.g. "MMU=y allnoconfig": "echo CONFIG_MMU=y > allno.config && make KCONFIG_ALLCONFIG=1 allnoconfig"), we use plain "move" instead of "moves", and I got: CC arch/m68k/lib/uaccess.o {standard input}: Assembler messages: {standard input}:47: Error: operands mismatch -- statement `move.b %a0,(%a1)' ignored This happens because plain "move" doesn't support byte transfers between memory and address registers, while "moves" does. Fix the asm constraints for __generic_copy_from_user(), __generic_copy_to_user(), and __clear_user() to only use data registers when accessing userspace. Also, relax the asm constraints for 16-bit userspace accesses in __put_user() and __get_user(), as both "move" and "moves" do support such transfers between memory and address registers.

2013-06-24m68k: Remove inline strcpy() and strcat() implementationsGeert Uytterhoeven
Gcc may replace calls to standard string functions by open code and/or calls to other standard string functions. If the replacement function is not available out-of-line, link errors will happen. To avoid this, the out-of-line versions were provided by arch/m68k/lib/string.c, but they were usually not linked in anymore as typically none of its symbols are referenced by built-in code. However, if any module would need them, they would not be available. Hence remove the inline strcpy() and strcat() implementations, remove arch/m68k/lib/string.c, and let the generic string library code handle it. Impact on a typical kernel build seems minimal or nonexistent: - .text : 0x00001000 - 0x002aac74 (2728 KiB) - .data : 0x002ada48 - 0x00392148 ( 914 KiB) + .text : 0x00001000 - 0x002aacf4 (2728 KiB) + .data : 0x002adac8 - 0x00392148 ( 914 KiB) See also commit e00c73ee05dc38ecaccced55d4f5fc58b0b769f7 ("m68k: Remove inline strlen() implementation").

into devel-stable This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems. It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and Tegra, with processors hitting low-power states requiring warm-boot resume through the cpu_resume code path.
