* [MIPS] Use USECS_PER_SEC / HZ instead of tick_usec in do_gettimeofday.Atsushi Nemoto2006-03-011-2/+3
| | | | | | | | | | | 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. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Initialize S-cache function pointers even on S-cache-less CPUs.Ralf Baechle2006-02-281-5/+11
| | | | | | | | | | | | When a CPU has no scache, the scache flushing functions currently aren't getting initialized and the NULL pointer is eventually called as a function. Initialize the scache flushing functions as a noop when there's no scache. Initial patch by me and most of the debugging done by Martin Michlmayr.

* [MIPS] SMP: Fix initialization order bug.Ralf Baechle2006-02-276-29/+30
| | | | | | | | | | | | | | 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 linkatUlrich Drepper2006-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Rojhalat Ibrahim2006-02-211-0/+20
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); and some debug printk() were duplicating each other...
