x86_64: Untangle asm/hpet.h from asm/timex.h

2007-07-22T01:37:08+00:00

When making changes to x86_64 timers, I noticed that touching hpet.h triggered
an unreasonably large rebuild.  Untangling it from timex.h quiets the extra
rebuild quite a bit.

[SPARC64]: Stop using drivers/char/rtc.c

2007-07-21T00:15:48+00:00

The existing sparc64 mini_rtc driver can handle CMOS based
rtcs trivially with just a few lines of code and the simplifies
things tremendously.

Tested on SB1500.

RTC: Ratelimit "lost interrupts" message

2007-07-16T16:05:43+00:00

We gets lots of these when the kernel is running on a hypervisor.  Zach says
"a guest kernel trying to get high frequency RTC will also be inaccurate, and
inevitably will have unhidable interrupt lateness."

[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59+00:00

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

[PATCH] sysctl: remove sys_sysctl support from drivers/char/rtc.c

2007-02-14T16:09:57+00:00

The real time clock driver was using the binary number reserved for cdroms in
the sysctl binary number interface, which is a no-no.  So since the sysctl
binary interface is wrong remove it.

[PATCH] Char: timers cleanup

2007-02-12T17:48:30+00:00

- Use timer macros to set function and data members and to modify
  expiration time.
- Use DEFINE_TIMER for global timers and do not init them at run-time in
  these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
  function if it's still running.

[PATCH] RTC driver init adjustment

2006-12-13T17:05:52+00:00

- conditionalizes procfs code upon CONFIG_PROC_FS (to reduce code size when
  that option is not enabled)

- make initialization no longer fail when the procfs entry can't be
  allocated (namely would initialization always have failed when
  CONFIG_PROC_FS was not set)

- move the formerly file-scope static variable rtc_int_handler_ptr into
  the only function using it, and makes it automatic.

[PATCH] rtc: fx error case

2006-12-13T17:05:52+00:00

Ensure RTC driver doesn't use its timer when it doesn't get to set it up
(as it cannot currently prevent other of its functions to be called from
outside when not built as a module - probably this should also be
addressed).
