2011-04-13avr32: add ATAG_BOARDINFOAndreas Bießmann2-0/+24
The ATAG_BOARDINFO is intended to hand over the information bd->bi_board_number from u-boot to the kernel. This piece of information can be used to implement some kind of board identification while booting the kernel. Therefore it is placed in .initdata section and can be accessed via the new symbol board_number only while initializing the kernel.

2011-04-13don't check platform_get_irq's return value against zeroUwe Kleine-König1-1/+1
platform_get_irq returns -ENXIO on failure, so !int_irq was probably always true. Better use (int)int_irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

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.

When writing out /sys/kernel/debug/at32ap_clk, clock list lock is being held while clk_get() is called. clk_get() attempts to take the same lock, which results in deadlock.

Further, even if napping is never actually enabled, just having CPU_FTR_CAN_NAP will cause machine_init() to overwrite the board's supplied ppc_md.power_save().

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.

2011-04-11PM / 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.

2011-04-06xen: Allow PV-OPS kernel to detect whether XSAVE is supportedShan Haitao1-1/+10
Xen fails to mask XSAVE from the cpuid feature, despite not historically supporting guest use of XSAVE. However, now that XSAVE support has been added to Xen, we need to reliably detect its presence. The most reliable way to do this is to look at the OSXSAVE feature in cpuid which is set iff the OS (Xen, in this case), has set CR4.OSXSAVE.

2011-04-06xen: just completely disable XSAVEJeremy Fitzhardinge1-17/+1
Some (old) versions of Xen just kill the domain if it tries to set any unknown bits in CR4, so we can't reliably probe for OSXSAVE in CR4. Since Xen doesn't support XSAVE for guests at the moment, and no such support is being worked on, there's no downside in just unconditionally masking XSAVE support.

2011-04-06KVM: move and fix substitue search for missing CPUID entriesAndre Przywara1-6/+25
If KVM cannot find an exact match for a requested CPUID leaf, the code will try to find the closest match instead of simply confessing it's failure. The implementation was meant to satisfy the CPUID specification, but did not properly check for extended and standard leaves and also didn't account for the index subleaf. Beside that this rule only applies to CPUID intercepts, which is not the only user of the kvm_find_cpuid_entry() function. So fix this algorithm and call it from kvm_emulate_cpuid(). This fixes a crash of newer Linux kernels as KVM guests on AMD Bulldozer CPUs, where bogus values were returned in response to a CPUID intercept.

2011-04-06KVM: fix XSAVE bit scanningAndre Przywara1-3/+3
When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area leaves, it assumes that the leaves are contigious and stops at the first zero one. On AMD hardware there is a gap, though, as LWP uses leaf 62 to announce it's state save area. So lets iterate through all 64 possible leaves and simply skip zero ones to also cover later features.
