m32r: Convert m32r to use read/update_peristent_clock

2010-03-13T00:14:12Z

This patch converts the m32r architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future. I have not built or tested this patch, so help from arch maintainers would be appreciated.

arch/m32r: Use DIV_ROUND_CLOSEST

2009-11-03T23:31:50Z

The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ @depends on haskernel@ expression x,__divisor; @@ - (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // Signed-off-by: Julia Lawall Signed-off-by: Hirokazu Takata

m32r: add rtc_lock variable

Add a spinlock variable "rtc_lock". This is taken from arch/arm/kernel/time.c. Signed-off-by: Hirokazu Takata

m32r: convert to use arch_gettimeoffset()

2009-09-22T14:17:43Z

Convert m32r to use GENERIC_TIME via the arch_getoffset() infrastructure, reducing the amount of arch specific code we need to maintain. I also noted that m32r doesn't seem to be taking the xtime write lock before calling do_timer()! That looks like a pretty bad bug to me. If folks agree, let me know and I can move the lock grab to the correct spot. Signed-off-by: John Stultz Cc: Hirokazu Takata Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

cpumask: remove references to struct irqaction's mask field.

2009-03-30T11:35:14Z

Impact: cleanup It's unused, since about 1995. So remove all initialization of it in preparation for actually removing the field. Signed-off-by: Rusty Russell Acked-by: Thomas Gleixner

[PATCH] kill wall_jiffies

2006-10-01T07:39:27Z

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.
