2012-03-07ARM: 7358/1: perf: add PMU hotplug notifierLorenzo Pieralisi
When a CPU is taken out of reset, either cold booted or hotplugged in, some of its PMU registers can contain UNKNOWN values. This patch adds a hotplug notifier to ARM core perf code so that upon CPU restart the PMU unit is reset and becomes ready to use again.

2012-03-07ARM: 7357/1: perf: fix overflow handling for xscale2 PMUsWill Deacon
xscale2 PMUs indicate overflow not via the PMU control register, but by a separate overflow FLAG register instead. This patch fixes the xscale2 PMU code to use this register to detect to overflow and ensures that we clear any pending overflow when disabling a counter.

2012-03-07ARM: 7356/1: perf: check that we have an event in the PMU IRQ handlersWill Deacon
The PMU IRQ handlers in perf assume that if a counter has overflowed then perf must be responsible.

2012-03-07ARM: 7355/1: perf: clear overflow flag when disabling counter on ARMv7 PMUWill Deacon
When disabling a counter on an ARMv7 PMU, we should also clear the overflow flag in case an overflow occurred whilst stopping the counter. This prevents a spurious overflow being picked up later and leading to either false accounting or a NULL dereference.

2012-03-07ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling modeWill Deacon
On ARM, the PMU does not stop counting after an overflow and therefore IRQ latency affects the new counter value read by the kernel. This is significant for non-sampling runs where it is possible for the new value to overtake the previous one, causing the delta to be out by up to max_period events. Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency") attempted to fix this problem by allowing interrupt handlers to pass an overflow flag to the event update function, causing the overflow calculation to assume that the counter passed through zero when going from prev to new. Unfortunately, this doesn't work when overflow occurs on the perf_task_tick path because we have the flag cleared and end up computing a large negative delta. This patch removes the overflow flag from armpmu_event_update and instead limits the sample_period to half of the max_period for non-sampling profiling runs.

2012-03-06x86: fix typo in recent find_vma_prev purgeLinus Torvalds
It turns out that test-compiling this file on x86-64 doesn't really help, because much of it is x86-32-specific. And so I hadn't noticed the slightly over-eager removal of the 'r' from 'addr' variable despite thinking I had tested it. Signed-off-by: Linus "oopsie" Torvalds <torvalds@linux-foundation.org>
2012-03-06vm: avoid using find_vma_prev() unnecessarilyLinus Torvalds
Several users of "find_vma_prev()" were not in fact interested in the previous vma if there was no primary vma to be found either. And in those cases, we're much better off just using the regular "find_vma()", and then "prev" can be looked up by just checking vma->vm_prev. The find_vma_prev() semantics are fairly subtle (see Mikulas' recent commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return prev by reference" means that it generates worse code too. Thus this "let's avoid using this inconvenient and clearly too subtle interface when we don't really have to" patch.

2012-03-02perf/x86/kvm: Fix Host-Only/Guest-Only counting with SVM disabledJoerg Roedel
It turned out that a performance counter on AMD does not count at all when the GO or HO bit is set in the control register and SVM is disabled in EFER. This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.

2012-03-01x86/PCI: do not tie MSI MS-7253 use_crs quirk to BIOS versionJonathan Nieder
Carlos was getting WARNING: at drivers/pci/pci.c:118 pci_ioremap_bar+0x24/0x52() when probing his sound card, and sound did not work. After adding pci=use_crs to the kernel command line, no more trouble. Ok, we can add a quirk. dmidecode output reveals that this is an MSI MS-7253, for which we already have a quirk, but the short-sighted author tied the quirk to a single BIOS version, making it not kick in on Carlos's machine with BIOS V1.2. If a later BIOS update makes it no longer necessary to look at the _CRS info it will still be harmless, so let's stop trying to guess which versions have and don't have accurate _CRS tables.

2012-03-01ARM: S3C24XX: Fix restart on S3C2442Heiko Stuebner
Commit b27b072791dc (ARM: 7265/1: restart: S3C24XX: use new restart hook) introduced the new restart hook also for the S3C244x cpus, but it was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was selected. Devices using the S3C2442 like the GTA02 normally don't select this CPU which leads to compilation errors like: LD .tmp_vmlinux1 arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference to `s3c2440_restart' make: *** [.tmp_vmlinux1] Error 1 Therefore move the s3c2440_restart function to s3c244x.c which is common to both cpus and also fix the naming to reflect this.

The following commit: 2f31b51659c2d8315ea2888ba5b93076febe672b Author: Tero Kristo <t-kristo@ti.com> Date: Fri Dec 16 14:37:00 2011 -0700 ARM: OMAP4: PRM: use PRCM interrupt handler introduced the PRCM interrupt handler and thus the need for 64 more interrupts. Since SPARSE_IRQ is still not fully functional on OMAP, the NR_IRQS needs to be updated to avoid the failure that happen during irq_alloc_descs call inside the PRCM driver: [ 0.208221] PRCM: failed to allocate irq descs: -12 Later the mux framework is then unable to request an IRQ from the PRCM interrupt handler. [ 1.802795] mux: Failed to setup hwmod io irq -22 Fix that by adding 64 more interrupts for OMAP2PLUS config.

2012-02-28x86/PCI: use host bridge _CRS info on MSI MS-7253Jonathan Nieder
In the spirit of commit 29cf7a30f8a0 ("x86/PCI: use host bridge _CRS info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by default on a board that needs it. This fixes boot failures and oopses introduced in 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci read out res"). The quirk is quite targetted (to a specific board and BIOS version) for two reasons: (1) to emphasize that this method of tackling the problem one quirk at a time is a little insane (2) to give BIOS vendors an opportunity to use simpler tables and allow us to return to generic behavior (whatever that happens to be) with a later BIOS update In other words, I am not at all happy with having quirks like this. But it is even worse for the kernel not to work out of the box on these machines, so...

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu IOMMU fixes for Linux 3.3-rc5 All the fixes are for the OMAP IOMMU driver. The first patch is the biggest one. It fixes the calls of the function omap_find_iovm_area() in the omap-iommu-debug module which expects a 'struct device' parameter since commit fabdbca instead of an omap_iommu handle. The omap-iommu-debug code still passed the handle to the function which caused a crash. The second patch fixes a NULL pointer dereference in the OMAP code and the third patch makes sure that the omap-iommu is initialized before the omap-isp driver, which relies on the iommu. The last patch is only a workaround until defered probing is implemented. * tag 'iommu-fixes-v3.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp iommu/omap: fix NULL pointer dereference iommu/omap: fix erroneous omap-iommu-debug API calls
