A large overhaul of the posix CPU timer code which is a preparation # for moving the CPU timer expiry out into task work so it can be # properly accounted on the task/process. # # An update to the bogus permission checks will come later during the # merge window as feedback was not complete before heading of for # travel. # # - Switch the timerqueue code to use cached rbtrees and get rid of the # homebrewn caching of the leftmost node. # # - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a # single function # # - Implement the separation of hrtimers to be forced to expire in hard # interrupt context even when PREEMPT_RT is enabled and mark the # affected timers accordingly. # # - Implement a mechanism for hrtimers and the timer wheel to protect # RT against priority inversion and live lock issues when a (hr)timer # which should be canceled is currently executing the callback. # Instead of infinitely spinning, the task which tries to cancel the # timer blocks on a per cpu base expiry lock which is held and # released by the (hr)timer expiry code. # # - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests # resulting in faster access to timekeeping functions. # # - Updates to various clocksource/clockevent drivers and their device # tree bindings. # # - The usual small improvements all over the place" # # * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (101 commits) # posix-cpu-timers: Fix permission check regression # posix-cpu-timers: Always clear head pointer on dequeue # hrtimer: Add a missing bracket and hide `migration_base' on !SMP # posix-cpu-timers: Make expiry_active check actually work correctly # posix-timers: Unbreak CONFIG_POSIX_TIMERS=n build # tick: Mark sched_timer to expire in hard interrupt context # hrtimer: Add kernel doc annotation for HRTIMER_MODE_HARD # x86/hyperv: Hide pv_ops access for CONFIG_PARAVIRT=n # posix-cpu-timers: Utilize timerqueue for storage # posix-cpu-timers: Move state tracking to struct posix_cputimers # posix-cpu-timers: Deduplicate rlimit handling # posix-cpu-timers: Remove pointless comparisons # posix-cpu-timers: Get rid of 64bit divisions # posix-cpu-timers: Consolidate timer expiry further # posix-cpu-timers: Get rid of zero checks # rlimit: Rewrite non-sensical RLIMIT_CPU comment # posix-cpu-timers: Respect INFINITY for hard RTTIME limit # posix-cpu-timers: Switch thread group sampling to array # posix-cpu-timers: Restructure expiry array # posix-cpu-timers: Remove cputime_expires # ... # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 7f2444d38f6bbfa12bc15e2533d8f9daa85ca02b # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_pseries_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- pseries_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_pseries_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1465:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bridge/br_netlink.c: In function 'br_afspec.isra.28': /kisskb/src/net/bridge/br_netlink.c:648:7: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/net/core/devlink.c: In function 'devlink_fmsg_prepare_skb': /kisskb/src/net/core/devlink.c:4443:6: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2065:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1674:3: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/futex.c:1649:6: note: 'oldval' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:613:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1836:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1749:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_pseries_defconfig_powerpc-gcc4.6 # Build took: 0:02:56.599106
