  • d12b0e24c   xtensa: Switch do_timer() to xtime_update() ... Browse Code »

    xtime_update() takes the xtime_lock itself.

    set_linux_timer() does not need to be protected by xtime_lock.

    [ tglx: This code is broken on SMP anyway. ]

  • 104f9c471   xtensa: Fix unnecessary setting of xtime ... Browse Code »

    xtensa supports read_persisitent_clock(), so there is no reason for
    the arch specific code to be setting xtime. Setting xtime will be
    done by the generic timekeeping code.

  • d4f587c67   timekeeping: Increase granularity of read_persistent_clock() ... Browse Code »

    The persistent clock of some architectures (e.g. s390) have a
    better granularity than seconds. To reduce the delta between the
    host clock and the guest clock in a virtualized system change the
    read_persistent_clock function to return a struct timespec.

  • 4476c9676   xtensa: remove platform rtc hooks ... Browse Code »

    platform_get/set_rtc_time() is not implemented by any of the supported
    xtensa platforms. Remove the facility completely.

    The initial seconds for xtime come from read_persistent_clock() which
    returns just 0 in the generic implementation. Platforms that sport a
    persistent clock can implement this function.

    This is needed to implement the ccount as a clock source.

    will be used instead.

  • 6c81c32f9   calibrate_delay() must be __cpuinit ... Browse Code »

    calibrate_delay() must be __cpuinit, not __{dev,}init.

    I've verified that this is correct for all users.

    While doing the latter, I also did the following cleanups:
    - remove pointless additional prototypes in C files
    - ensure all users #include

    This fixes the following section mismatches with CONFIG_HOTPLUG=n,
    CONFIG_HOTPLUG_CPU=y:

    WARNING: vmlinux.o(.text+0x1128d): Section mismatch: reference to .init.text.1:calibrate_delay (between 'check_cx686_slop' and 'set_cx86_reorder')
    WARNING: vmlinux.o(.text+0x25102): Section mismatch: reference to .init.text.1:calibrate_delay (between 'smp_callin' and 'cpu_coregroup_map')

  • 8ef386092   [PATCH] kill wall_jiffies ... Browse Code »

    With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
    So we can kill wall_jiffies completely.

    This is just a cleanup and logically should not change any real behavior
    except for one thing: RTC updating code in (old) ppc and xtensa use a
    condition "jiffies - wall_jiffies == 1". This condition is never met so I
    suppose it is just a bug. I just remove that condition only instead of
    kill the whole "if" block.

  • 3171a0305   [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) ... Browse Code »

    Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
    timer interrupt handler with this change.

    Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
    callers of do_timer() should know how many ticks to update. Passing ticks
    get rid of this redundant calculation. Also there are another redundancy
    pointed out by Martin Schwidefsky.

    This cleanup make a barrier added by
    5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes
    it.

    As a bonus, this cleanup make wall_jiffies can be removed easily, since now
    wall_jiffies is always synced with jiffies. (This patch does not really
    remove wall_jiffies. It would be another cleanup patch)

  • 34af946a2   [PATCH] spin/rwlock init cleanups ... Browse Code »

    locking init cleanups:

    - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
    - convert rwlocks in a similar manner

    this patch was generated automatically.

    Motivation:

    - cleanliness
    - lockdep needs control of lock initialization, which the open-coded
    variants do not give
    - it's also useful for -rt and for lock debugging in general

  • b149ee223   [PATCH] NTP: ntp-helper functions ... Browse Code »

    This patch cleans up a commonly repeated set of changes to the NTP state
    variables by adding two helper inline functions:

    ntp_clear(): Clears the ntp state variables

    ntp_synced(): Returns 1 if the system is synced with a time server.

    This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,
    sparc64.
