2008-01-14w1: decrement slave counter only in ->release() callbackEvgeniy Polyakov
Decrement the slave counter only in ->release() callback instead of both in ->release() and w1 control. Patch is based on debug work and preliminary patch made by Henri Laakso. Henri noticed in debug that this counter becomes negative after w1 slave device is physically removed.

2008-01-12pnpacpi: print resource shortage message only onceLen Brown
pnpacpi: exceeded the max number of IO resources: 40 While this message is a real error and should thus remain KERN_ERR (even a new dmesg line is seen as a regression by some, since it was not printed in 2.6.23...) it is certainly impolite to print this warning 50 times should you happen to have the oddball system with 90 io resources under a device... So print the warning just once. In 2.6.25 we'll get rid of the limits altogether and these warnings will vanish with them. http://bugzilla.kernel.org/show_bug.cgi?id=9535 Signed-off-by: Len Brown <len.brown@intel.com>
2008-01-12sky2: remove check for PCI wakeup setting from BIOSStephen Hemminger

2008-01-12netxen: fix byte-swapping in tx and rxDhananjay Phadke
Here's the reworked patch. This cleans up some unnecessary byte-swapping while setting up tx and interpreting rx desc. The 64 bit rx status data should be converted to host endian format only once and the macros just need to extract bitfields.

2008-01-12netxen: optimize tx handlingdhananjay@netxen.com
netxen driver allows limited number of threads simultaneously posting skb's in tx ring. If transmit slot is unavailable, driver calls schedule() or loops in xmit_frame(). This patch returns TX_BUSY and lets the stack reschedule the packet if transmit slot is unavailable.

2008-01-11ps3fb: fix deadlock on kexec()Jeremy Kerr
Since the introduction of the acquire_console_sem calls in 0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the kernel to deadlock: ps3fb_shutdown() -> unregister_framebuffer() -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND) -> fbcon_fb_unbind() -> unbind_con_driver() -> bind_con_driver() [ acquires console_sem ] -> fbcon_deinit() -> fbops->fb_release(newinfo, 0) -> ps3fb_release() -> ps3fb_sync() [ acquires console_sem ] This change avoids the deadlock by moving the acquire_console_sem() out of ps3fb_sync(), and puts it into the two other callsites, leaving ps3fb_release() to call ps3fb_sync() without the console semaphore. [Geert] - Corrected call sequence above - ps3fb_release() may be called with and without console_sem held. This is an inconsistency that should be fixed at the fb level, but for now, try to acquire console_sem in ps3fb_release(). I think it's safer to let ps3fb_release() try to acquire console_sem and not refresh the screen if it fails, than to call ps3fb_sync() without holding console_sem, as ps3fb_par may be modified at the same time, causing crashes or lockups. Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen when display flipping is disabled, which is an uncommon case (except during shutdown/kexec).

2008-01-11PM: ACPI and APM must not be enabled at the same timeLen Brown
ACPI and APM used "pm_active" to guarantee that they would not be simultaneously active. But pm_active was recently moved under CONFIG_PM_LEGACY, so that without CONFIG_PM_LEGACY, pm_active became a NOP -- allowing ACPI and APM to both be simultaneously enabled. This caused unpredictable results, including boot hangs. Further, the code under CONFIG_PM_LEGACY is scheduled for removal. So replace pm_active with pm_flags. pm_flags depends only on CONFIG_PM, which is present for both CONFIG_APM and CONFIG_ACPI. http://bugzilla.kernel.org/show_bug.cgi?id=9194 Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Rafael J.

2008-01-10libata: don't normalize UNKNOWN to NONE after resetTejun Heo
After non-classifying reset, ehc->classes[] could contain ATA_DEV_UNKNOWN which used to be normalized to ATA_DEV_NONE for consistency. However, this causes unfortunate side effect for drivers which have non-classifying hardresets (e.g. sata_nv) by making hardreset report ATA_DEV_NONE for non-classifying resets and thus makes EH believe that the port is unoccupied and recovery can be skipped. The end result is that after a device is swapped with another one, the new device isn't attached after the old one is detached. This patch makes ata_eh_reset() not normalize UNKNOWN to NONE after non-classifying resets. This fixes the above problem. As UNKNOWN and NONE are handled differently by only EH hotplug logic, this doesn't cause other behavior changes.
