2008-06-06sched: fix cpupri hotplug supportGregory Haskins
The RT folks over at RedHat found an issue w.r.t. hotplug support which was traced to problems with the cpupri infrastructure in the scheduler: https://bugzilla.redhat.com/show_bug.cgi?id=449676 This bug affects 23-rt12+, 24-rtX, 25-rtX, and sched-devel. This patch applies to 25.4-rt4, though it should trivially apply to most cpupri enabled kernels mentioned above. It turned out that the issue was that offline cpus could get inadvertently registered with cpupri so that they were erroneously selected during migration decisions. The end result would be an OOPS as the offline cpu had tasks routed to it. This patch generalizes the old join/leave domain interface into an online/offline interface, and adjusts the root-domain/hotplug code to utilize it. I was able to easily reproduce the issue prior to this patch, and am no longer able to reproduce it after this patch. I can offline cpus indefinately and everything seems to be in working order. Thanks to Arnaldo (acme), Thomas, and Peter for doing the legwork to point me in the right direction. Also thank you to Peter for reviewing the early iterations of this patch.

2008-06-04libata-sff: Fix oops reported in kerneloops.org for pnp devices with no ctlAlan Cox
- Make ata_sff_altstatus private so nobody uses it by mistake - Drop the 400nS delay from it Add ata_sff_irq_status - encapsulates the IRQ check logic This function keeps the existing behaviour for altstatus using devices. I actually suspect the logic was wrong before the changes but -rc isn't the time to play with that ata_sff_sync - ensure writes hit the device Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so that we can fix the nasty delay this causes on most systems. - ata_sff_pause - 400nS delay Ensure the command hit the device and delay 400nS - ata_sff_dma_pause Ensure the I/O hit the device and enforce an HDMA1:0 transition delay. Requires altstatus register exists, BUG if not so we don't risk corruption in MWDMA modes. (UDMA the checksum will save your backside in theory) The only other complication then is devices with their own handlers. rb532 can use dma_pause but scc needs to access its own altstatus register for internal errata workarounds so directly call the drivers own altstatus function.

2008-06-03serial_core: uart_set_ldisc infrastructureAlan Cox
The tty layer provides a callback that is used when the line discipline is changed. Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.

2008-06-02sh: fix miscompilation of ip_fast_csum with gcc >= 4.3Paul Mundt
As noted by Matthew Wilcox: Kyle McMartin just tracked down a bug on parisc to a missing "memory" clobber in the inline assembly implementation of ip_fast_csum. The FRV, SH and Xtensa ports are also missing a memory clobber, so I thought it would be polite to let you know. The bug manifests as dropped network packets (obviously they have the wrong checksum). It started appearing for parisc with GCC 4.3. The GCC manual says: If your assembler instructions access memory in an unpredictable fashion, add `memory' to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. I see that FRV has a 400 byte memory output which may prevent this problem from appearing, but SH and Xtensa have nothing to prevent this bug. Hope this saves you a few days of debugging.

2008-05-30Input: rename SW_RADIO to SW_RFKILL_ALLHenrique de Moraes Holschuh
The SW_RADIO code for EV_SW events has a name that is not descriptive enough of its intended function, and could induce someone to think KEY_RADIO is its EV_KEY counterpart, which is false. Rename it to SW_RFKILL_ALL, and document what this event is for. Keep the old name around, to avoid userspace ABI breaks. The SW_RFKILL_ALL event is meant to be used by rfkill master switches. It is not bound to a particular radio switch type, and usually applies to all types. It is semantically tied to master rfkill switches that enable or disable every radio in a system.
