2010-03-24[S390] zcore: CPU registers are not saved under LPARMichael Holzheu
To save the registers for all CPUs a sigp "store status" is done that stores the registers to address absolute zero. To access storage at absolute zero, normally the address of the prefix register of the accessing CPU has to be used. This does not work when large pages are active (currently only under LPAR). In order to fix that problem, instead of memcpy memcpy_real is used, which switches to real mode where prefixing works.

2010-03-24pcmcia: use dev_pm_ops for class pcmcia_socket_classDominik Brodowski
Instead of requiring PCMCIA socket drivers to call various functions during their (bus) resume and suspend functions, register an own dev_pm_ops for this class. This fixes several suspend/resume bugs seen on db1xxx-ss, and probably on some other socket drivers, too. With regard to the asymmetry with only _noirq suspend, but split up resume, please see bug 14334 and commit 9905d1b411946fb3 . Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2010-03-24power: support _noirq actions on device types and classesDominik Brodowski
The new-style dev_pm_ops provide callbacks for both IRQs enabled and disabled. However, the _noirq variants were only called for buses registered with a device, not for classes and types. In order to properly use dev_pm_ops in class pcmcia_socket_class, support _noirq actions also on classes and types. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Acked-by: Rafael J.

2010-03-23bnx2: Fix netpoll crash.Benjamin Li
The bnx2 driver calls netif_napi_add() for all the NAPI structs during ->probe() time but not all of them will be used if we're not in MSI-X mode. This creates a problem for netpoll since it will poll all the NAPI structs in the dev_list whether or not they are scheduled, resulting in a crash when we access structure fields not initialized for that vector. We fix it by moving the netif_napi_add() call to ->open() after the number of IRQ vectors has been determined.

2010-03-23libata-sff: fix spurious IRQ handlingTejun Heo
Commit 27943620cbd960f710a385ff4a538e14ed3f1922 introduced spurious IRQ handling but it has a race condition where valid completion can be lost while trying to clear spurious IRQ leading to occassional command timeouts. This patch improves SFF interrupt handler such that 1. Once BMDMA HSM is stopped, the condition is never considered spurious. As there's no way to resume stopped BMDMA HSM, if device status doesn't agree with BMDMA status, the only way out is aborting the command (otherwise, it will just end up timing out). 2. ap->ops->sff_check_status() can be safely called to clear spurious device IRQ as it atomically returns completion status but BMDMA IRQ status can't be cleared in safe way if command is in flight. After a spurious IRQ, call ap->ops->sff_irq_clear() only if the respective device is idle and retry completion if sff_check_status() indicates command completion. Please note that ata_piix uses bmdma_status for sff_irq_check() and #2 won't weaken spurious IRQ handling even with in-flight command because if bmdma_status indicates IRQ pending but device status is not on spurious check, the next IRQ handler invocation will abort the command due to #1. This fixes bko#15537. https://bugzilla.kernel.org/show_bug.cgi?id=15537 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Andrew Benton <b3nton@gmail.com> Cc: Petr Uzel <petr.uzel@centrum.cz> Cc: Rafael J.

2010-03-23ACPI / ACPICA: Do not check reference counters in acpi_ev_enable_gpe()Rafael J. Wysocki
acpi_ev_enable_gpe() should enable the GPE at the hardware level regardless of the value of the GPE's runtime reference counter. There are only two callers of acpi_ev_enable_gpe(), acpi_enable_gpe() and acpi_set_gpe(). The first one checks the GPE's runtime reference counter itself and only calls acpi_ev_enable_gpe() if it's equal to one, and the other one is supposed to enable the GPE unconditionally (if called with ACPI_GPE_ENABLE). This change fixes the problem in acpi_enable_wakeup_device() where the GPE will not be enabled for wakeup if it's runtime reference counter is zero, which is a regression from 2.6.33.

2010-03-19ixgbevf: Fix VF Stats accounting after resetGreg Rose
The counters in the 82599 Virtual Function are not clear on read. They accumulate to the maximum value and then roll over. They are also not cleared when the VF executes a soft reset, so it is possible they are non-zero when the driver loads and starts. This has all been accounted for in the code that keeps the stats up to date but there is one case that is not. When the PF driver is reset the counters in the VF are all reset to zero. This adds an additional accounting overhead into the VF driver when the PF is reset under its feet. This patch adds additional counters that are used by the VF driver to accumulate and save stats after a PF reset has been detected. Prior to this patch displaying the stats in the VF after the PF has reset would show bogus data.
