2014-03-20timer: Remove code redundancy while calling get_nohz_timer_target()Viresh Kumar4-22/+11
There are only two users of get_nohz_timer_target(): timer and hrtimer. Both call it under same circumstances, i.e. #ifdef CONFIG_NO_HZ_COMMON if (!pinned && get_sysctl_timer_migration() && idle_cpu(this_cpu)) return get_nohz_timer_target(); #endif So, it makes more sense to get all this as part of get_nohz_timer_target() instead of duplicating code at two places. For this another parameter is required to be passed to this routine, pinned.

Fix some "Bad rss-counter state" reports on exit, arising from the interaction between page migration and remap_file_pages(): zap_pte() must count a migration entry when zapping it.

Modify irq_domain_ops for CIU and CIU2 to "gracefully handle" GPIO lines (neither return error code nor call octeon_irq_set_ciu_mapping for it). This should avoid the warning. (As before the real setup for GPIO lines will happen using irq_domain_ops of gpio-controller.) This patch is based on Wei's patch v2 (see http://marc.info/?l=linux-mips&m=139511814813247).

2014-03-19irqchip: sun4i: Simplify sun4i_irq_ackHans de Goede1-6/+1
Now that we only ack irq 0 the code can be simplified a lot. Also switch from read / modify / write to a simple write clear: 1) This is what the android code does (it has a hack for acking irq 0 in its unmask code doing this) 2) read / modify / write simply does not make sense for an irq status register like this, if the other bits are writeable (and the data sheet says they are not) they should be write 1 to clear, since otherwise a read / modify / write can race with a device raising an interrupt and then clear the pending bit unintentionally Signed-off-by: Hans de Goede <[email protected]> Acked-by: Maxime Ripard <[email protected]> Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]>
2014-03-19irqchip: sun4i: Use handle_fasteoi_irq for all interruptsHans de Goede1-14/+4
Since the sun4i irq chip does not require any action and clears the interrupt when the level goes back to inactive, we don't need to mask / unmask for non oneshot IRQs, to achieve this we make sun4i_irq_ack a nop for all irqs except irq 0 and use handle_fasteoi_irq for all interrupts. Now there might be a case when the device reactivates the interrupt before the RETI. But that does not matter as we run the primary interrupt handlers with interrupts disabled. This also allows us to get rid of needing to use 2 irq_chip structs, this means that the IRQCHIP_EOI_THREADED | IRQCHIP_EOI_IF_HANDLED will now influence all interrupts rather then just irq 0, but that does not matter as the eoi is now a nop anyways for all interrupts but irq 0.

2014-03-18perf report: Merge al->filtered with hist_entry->filteredNamhyung Kim2-2/+2
I.e. don't drop al->filtered entries, create the hist_entries and use its ->filtered bitmap, that is kept with the same semantics for its bitmap, leaving the filtering to be done at the hist_entry level, i.e. in the UIs. This will allow zooming in/out the filters.

2014-03-18perf symbols: Apply all filters to an addr_locationNamhyung Kim1-10/+4
Instead of bailing out as soon as we find a filter that applies, go on checking all of them so that we can zoom in/out filters. We also need to make sure we only update al->filtered after thread__find_addr_map(), because there is where al->filtered gets initialized to zero. This will increase the cost of processing when all we don't need this toggling, but will provide flexibility for the TUI and GTK+ interfaces, that will incur in creating the hist_entries just once.

2014-03-18perf symbols: Record the reason for filtering an address_locationNamhyung Kim6-17/+25
By turning the addr_location->filtered member from a boolean to a u8 bitmap, reusing (and extending) the hist_filter enum for that. This patch doesn't change the logic at all, as it keeps the meaning of al->filtered !0 to mean that the entry _was_ filtered, so no change in how this value is interpreted needs to be done at this point. This will be soon used in upcoming patches.

2014-03-18Revert "[PATCH] Insert GART region into resource map"Bjorn Helgaas1-19/+1
This reverts commit 56dd669a138c, which makes the GART visible in /proc/iomem. This fixes a regression: e501b3d87f00 ("agp: Support 64-bit APBASE") exposed an existing problem with a conflict between the GART region and a PCI BAR region. The GART addresses are bus addresses, not CPU addresses, and therefore should not be inserted in iomem_resource. On many machines, the GART region is addressable by the CPU as well as by an AGP master, but CPU addressability is not required by the spec. On some of these machines, the GART is mapped by a PCI BAR, and in that case, the PCI core automatically inserts it into iomem_resource, just as it does for all BARs. Inserting it here means we'll have a conflict if the PCI core later tries to claim the GART region, so let's drop the insertion here. The conflict indirectly causes X failures, as reported by Jouni in the bugzilla below. We detected the conflict even before e501b3d87f00, but after it the AGP code (fix_northbridge()) uses the PCI resource (which is zeroed because of the conflict) instead of reading the BAR again.

2014-03-18libata: async resumeTodd Brandt1-1/+1
Improve overall system resume time by making libata link recovery actions asynchronous relative to other resume events. Link resume operations are performed using the scsi_eh thread, so commands, particularly the sd resume start/stop command, will be held off until the device exits error handling. Libata already flushes eh with ata_port_wait_eh() in the port teardown paths, so there are no concerns with async operation colliding with the end-of-life of the ata_port object. Also, libata-core is already careful to flush in-flight pm operations before another round of pm starts on the given ata_port.

2014-03-18libata, libsas: kill pm_result and related cleanupDan Williams5-124/+71
Tejun says: "At least for libata, worrying about suspend/resume failures don't make whole lot of sense. If suspend failed, just proceed with suspend. If the device can't be woken up afterwards, that's that. There isn't anything we could have done differently anyway. The same for resume, if spinup fails, the device is dud and the following commands will invoke EH actions and will eventually fail. Again, there really isn't any *choice* to make. Just making sure the errors are handled gracefully (ie. don't crash) and the following commands are handled correctly should be enough." The only libata user that actually cares about the result from a suspend operation is libsas. However, it only cares about whether queuing a new operation collides with an in-flight one. All libsas does with the error is retry, but we can just let libata wait for the previous operation before continuing. Other cleanups include: 1/ Unifying all ata port pm operations on an ata_port_pm_ prefix 2/ Marking all ata port pm helper routines as returning void, only ata_port_pm_ entry points need to fake a 0 return value. 3/ Killing ata_port_{suspend|resume}_common() in favor of calling ata_port_request_pm() directly 4/ Killing the wrappers that just do a to_ata_port() conversion 5/ Clearly marking the entry points that do async operations with an _async suffix.
