* [IA64] fix arch/ia64/mm/contig.c:235: warning: unused variable `nid'Tony Luck2006-12-12
| | | | | | | | | | | This warning only shows up with CONFIG_VIRTUAL_MEM_MAP=y and CONFIG_FLATMEM=y. There is only one caller left for register_active_ranges() from the contig.c code ... so it doesn't need to pick up the node number, the node number is always zero.

* [IA64] Kexec/Kdump: honour non-zero crashkernel offset.Horms2006-12-12
| | | | | | | | | | | | | | | | | | There seems to be a value in both allowing the kernel to determine the base offset of the crashkernel automatically and allowing users's to sepcify it. The old behaviour on ia64, which is still the current behaviour on most architectures is for the user to always specify the address. Recently ia64 was changed so that it is always automatically determined. With this patch the kernel automatically determines the offset if the supplied value is 0, otherwise it uses the value provided. This should probably be backed by a documentation change.

* [IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutationsHorms2006-12-12
| | | | | | | | | | | | | | | | | | Actually, on reflection I think that there is a good case for keeping the options separate. I am thinking particularly of people who want a very small crashdump kernel and thus don't want to compile in kexec. The patch below should fix things up so that all valid combinations of KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on CRASH_DUMP which is why I said valid combinations. In a nutshell it just untangles unrelated code and switches around a few defines. Please note that it creats a new file, arch/ia64/kernel/crash_dump.c This is in keeping with the i386 implementation.

* [IA64] Do not call SN_SAL_SET_CPU_NUMBER twice on cpu 0Jay Lan2006-12-12
| | | | | | | | | | | | | | | | This is an SN specific patch. Architectually, cpu_init is always called twice on cpu 0 and thus resulted in two SN_SAL_SET_CPU_NUMBER calls. This was harmless in production kernel; however, it can cause problem on booting up a crashdump kernel at Altix. Here is the patch that detects the second sn_cpu_init call and skips the second call to SN_SAL_SET_CPU_NUMBER. Signed-Off-By: Jay Lan <jlan@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * sh: BUG() handling through trapa vector.Paul Mundt2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right. This also makes it trivial to wire up a DIE_BUG for the atomic die chain, which we couldn't really do before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * rtc: rtc-sh: alarm support.Jamie Lenehan2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds alarm support for the RTC_ALM_SET, RTC_ALM_READ, RTC_WKALM_SET and RTC_WKALM_RD operations to rtc-sh. The only unusual part is the handling of the alarm interrupt. If you clear the alarm flag (AF) while the time in the RTC still matches the time in the alarm registers than AF is immediately re-set, and if the alarm interrupt (AIE) is still enabled then it re-triggers. I was originally getting around 20k+ interrupts generated during the second when the RTC and alarm registers matches. The solution I've used is to clear AIE when the alarm goes off and then use the carry interrupt to re-enabled it. The carry interrupt will check AF and re-enabled AIE if it's clear. If AF is not clear it'll clear it and then the check will be repeated next carry interrupt. This a bit in rtc structure that indicates that it's waiting to have AIE re-enabled so it doesn't turn it on when it wasn't enabled anyway.

| * rtc: rtc-sh: fix rtc for out-by-one for the month.Jamie Lenehan2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RMONCNT register, which holds the month in the RTC, takes a value between 1 and 12 while the tm_mon field in the time structures takes a value between 0 and 11. This wasn't being taken into account in rtc-sh resulting in the month being out by one. eg, on my board during boot the RTC is set to: RTC is set to Thu Jul 01 09:00:00 1999 but "hwclock -r" immediately after logging in was showing: Sun Aug 1 09:01:43 1999 0.000000 seconds Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

There's a minor discrepency between the number of bits used for the swap type encoding between 32 and 64-bit PTEs, but this is unlikely to cause any problem given the extended offset.

This is unique being a place where you can get called with BH on, off, or IRQs off. Given that this is only used for printk, the easiest solution is probably just to disable local IRQs instead of BH.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dean Manners notices that when an IPVS synchonisation daemons are started the system load slowly climbs up to 1. This seems to be related to the call to ssleep(1) (aka msleep(1000) in the main loop. Replacing this with a call to msleep_interruptable() seems to make the problem go away. Though I'm not sure that it is correct. This is the second edition of this patch, which replaces ssleep() in the main loop for both the master and backup threads, as well as some thread synchronisation code. The latter is just for thorougness as it shouldn't be causing any problems. Signed-Off-By: Simon Horman <horms@verge.net.au> Signed-off-by: David S. Miller <davem@davemloft.net>
