[MIPS] Protect more of timer_interrupt() by xtime_lock.

2006-03-18T16:59:29+00:00

    
From Dave Johnson :

* do_timer() expects the arch-specific handler to take the lock as it
  modifies jiffies[_64] and xtime.
* writing timerhi/lo in timer_interrupt() will mess up
  fixed_rate_gettimeoffset() which reads timerhi/lo.

[MIPS] Discard .exit.text at runtime.

2006-03-09T18:05:09+00:00

    
At times gcc will place bits of __exit functions into .rodata.  If
compiled into the kernle itself we used to discard .exit.text - but
not the bits left in .rodata.  While harmless this did at times result
in a large number of warnings.  So until gcc fixes this, discard
.exit.text at runtime.

[MIPS] Use USECS_PER_SEC / HZ instead of tick_usec in do_gettimeofday.

2006-03-01T19:22:22+00:00

    
The 'tick_usec' is USER_HZ period in usec.  do_gettimeofday() should
use kernel HZ value.
    
Here is a patch for MIPS.  It seems m32r, m68k and sparc have same
problem though their HZ and USER_HZ are same for now.

[MIPS] SMP: Fix initialization order bug.

2006-02-27T17:30:36+00:00

    
A recent change requires cpu_possible_map to be initialized before
smp_sched_init() but most MIPS platforms were initializing their
processors in the prom_prepare_cpus callback of smp_prepare_cpus.  The
simple fix of calling prom_prepare_cpus from one of the earlier SMP
initialization hooks doesn't work well either since IPIs may require
init_IRQ() to have completed, so bit the bullet and split
prom_prepare_cpus into two initialization functions, plat_smp_setup
which is called early from setup_arch and plat_prepare_cpus called where
prom_prepare_cpus used to be called.

[PATCH] flags parameter for linkat

2006-02-24T22:31:39+00:00

I'm currently at the POSIX meeting and one thing covered was the
incompatibility of Linux's link() with the POSIX definition.  The name.
Linux does not follow symlinks, POSIX requires it does.

Even if somebody thinks this is a good default behavior we cannot change this
because it would break the ABI.  But the fact remains that some application
might want this behavior.

We have one chance to help implementing this without breaking the behavior.
 For this we could use the new linkat interface which would need a new
flags parameter.  If the new parameter is AT_SYMLINK_FOLLOW the new
behavior could be invoked.

I do not want to introduce such a patch now.  But we could add the
parameter now, just don't use it.  The patch below would do this.  Can we
get this late patch applied before the release more or less fixes the
syscall API?

[MIPS] Add topology_init.

2006-02-21T16:58:23+00:00

    
A recent patch introduced cpu topology in sysfs.  When you run a kernel
with SMP and sysfs enabled, you now get an Oops on boot. The following
patch fixes that by adding topology_init to arch/mips/kernel/smp.c. The
code is copied from arch/s390/kernel/smp.c.
