2011-04-18alpha: Fix RTC interrupt setup.Richard Henderson1-1/+1
Following commit 091738a266fc ("genirq: Remove real old transition functions") we removed an automatic conversion of no_irq_chip to dummy_irq_chip. This change needs to be propagated back into the alpha backend. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-04-18alpha: Remove set but unused variables.Richard Henderson5-17/+13
This is a new warning in gcc 4.6. Several of these variables are used within #if 0 code, which probably ought to be removed. Most of the changes are legitimate cleanups. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This patch disables GartTlbWlk errors on AMD Fam10h CPUs if the BIOS forgets to do is (or is just too old). Letting these errors enabled can cause a sync-flood on the CPU causing a reboot.

Round robin assignment doesn't work because init_numa_sched_groups_power() assumes all logical cpus in the same physical cpu share the same node (then it only accounts for group_first_cpu()), and the simple round robin breaks the above assumption. Thus, this patch implements a reassignment of node-ids if buggy firmware or numa emulation makes wrong cpu node map. Tt enforce all logical cpus in the same physical cpu share the same node.

Commit 1de1502c ("x86, um: now we can get rid of trivial uml headers") removed accidentally bug.h which broke UML's call tracer and bug handler. Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use of ud2. UML cannot use ud2, it raises SIGILL in user mode. As UML has a different stack for handling signals the call trace will be cut off.

2011-04-14Blackfin: SMP: make all barriers handle cache issuesGraf Yang1-18/+18
When suspending/resuming, the common task freezing code will run in parallel and freeze processes on each core. This is because the code uses the non-smp version of memory barriers (as well it should). The Blackfin smp barrier logic at the moment contains the cache sync logic, but the non-smp barriers do not. This is incorrect as Rafel summarized: > ... > The existing memory barriers are SMP barriers too, but they are more > than _just_ SMP barriers. At least that's how it is _supposed_ to be > (eg. rmb() is supposed to be stronger than smp_rmb()). > ... > However, looking at the blackfin's definitions of SMP barriers I see > that it uses extra stuff that should _also_ be used in the definitions > of the mandatory barriers. > ...

2011-04-13avr32: init cannot ignore signals sent by force_sig_info()Matt Fleming1-22/+0
We can delete the code that checks to see if we're sending an ignored signal to init because force_sig_info() already handles this case. force_sig_info() will kill init even if the signal handler is SIG_DFL and the scenario described in the comment where init might "generate the same exception over and over again" cannot occur (force_sig_info() clears SIGNAL_UNKILLABLE to ensure that init will die). Also, the use of is_global_init() is not correct in the multhreaded case, as Oleg Nesterov explains, "is_global_init() is not right in theory, /sbin/init can be multithreaded. And, this doesn't cover the sub-namespace inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking closer I think you can simply remove this code." It seems this code was copied from arch/powerpc in March 2007 in commit 623b0355d5b1 "[AVR32] Clean up exception handling code" but the code was deleted from arch/powerpc in November 2009 in commit a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()" So catch up with powerpc and delete the bogus code.

2011-04-12x86/mrst: Fix boot crash caused by incorrect pin to irq mappingJacob Pan1-5/+5
Moorestown systems crash on boot because the secondary CPU clockevent (apbt1) will fail to request irq#1, which does not have ioapic chip in its irq_desc[] entry. Background: Moorestown platform does not have ISA bus nor legacy IRQs. It reuses the range of legacy IRQs for regular device interrupts. The routing information of early system device IRQs (timers) are obtained from firmware provided SFI tables. We reuse/fake MP configuration table to facilitate IRQ setup with IOAPIC. Maintaining a 1:1 mapping of IOAPIC pin (RTE entry) and IRQ# makes routing information clean and easy to understand on Moorestown. Though optional. This patch allows SFI timer and vRTC IRQ to be treated as ISA IRQ so that pin2irq mapping will be 1:1. Also fixed MP table type and use macros to clearly set MP IRQ entries. As a result, apbt timer and RTC interrupts on Moorestown are within legacy IRQ range: # cat /proc/interrupts CPU0 CPU1 0: 11249 0 IO-APIC-edge apbt0 1: 0 12271 IO-APIC-edge apbt1 8: 887 0 IO-APIC-fasteoi dw_spi 13: 0 0 IO-APIC-fasteoi INTEL_MID_DMAC2 14: 0 0 IO-APIC-fasteoi rtc0 Further discussion of this patch can be found at: https://lkml.org/lkml/2010/6/10/70 Suggested-by: "Eric W.

2011-04-12PM / Hibernate: Introduce CONFIG_HIBERNATE_CALLBACKSRafael J. Wysocki1-3/+3
Xen save/restore is going to use hibernate device callbacks for quiescing devices and putting them back to normal operations and it would need to select CONFIG_HIBERNATION for this purpose. However, that also would cause the hibernate interfaces for user space to be enabled, which might confuse user space, because the Xen kernels don't support hibernation. Moreover, it would be wasteful, as it would make the Xen kernels include a substantial amount of code that they would never use. To address this issue introduce new power management Kconfig option CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code that is necessary for the hibernate device callbacks to work and make CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to select CONFIG_HIBERNATE_CALLBACKS without dragging the entire hibernate code along with it. Signed-off-by: Rafael J.
