2008-06-04x86: fix broken math-emu with lazy allocation of fpu areaSuresh Siddha
Fix the math emulation that got broken with the recent lazy allocation of FPU area. init_fpu() need to be added for the math-emulation path aswell for the FPU area allocation. math emulation enabled kernel booted fine with this, in the presence of "no387 nofxsr" boot param.

2008-06-04x86: enable preemption in delaySteven Rostedt
The RT team has been searching for a nasty latency. This latency shows up out of the blue and has been seen to be as big as 5ms! Using ftrace I found the cause of the latency. pcscd-2995 3dNh1 52360300us : irq_exit (smp_apic_timer_interrupt) pcscd-2995 3dN.2 52360301us : idle_cpu (irq_exit) pcscd-2995 3dN.2 52360301us : rcu_irq_exit (irq_exit) pcscd-2995 3dN.1 52360771us : smp_apic_timer_interrupt (apic_timer_interrupt ) pcscd-2995 3dN.1 52360771us : exit_idle (smp_apic_timer_interrupt) Here's an example of a 400 us latency. pcscd took a timer interrupt and returned with "need resched" enabled, but did not reschedule until after the next interrupt came in at 52360771us 400us later! At first I thought we somehow missed a preemption check in entry.S. But I also noticed that this always seemed to happen during a __delay call. pcscd-2995 3dN.2 52360836us : rcu_irq_exit (irq_exit) pcscd-2995 3.N.. 52361265us : preempt_schedule (__delay) Looking at the x86 delay, I found my problem. In git commit 35d5d08a085c56f153458c3f5d8ce24123617faf, Andrew Morton placed preempt_disable around the entire delay due to TSC's not working nicely on SMP. Unfortunately for those that care about latencies this is devastating! Especially when we have callers to mdelay(8). Here I enable preemption during the loop and account for anytime the task migrates to a new CPU. The delay asked for may be extended a bit by the migration, but delay only guarantees that it will delay for that minimum time. Delaying longer should not be an issue. [ Thanks to Thomas Gleixner for spotting that cpu wasn't updated, and to place the rep_nop between preempt_enabled/disable. ] Signed-off-by: Steven Rostedt <srostedt@redhat.com> Cc: akpm@osdl.org Cc: Clark Williams <clark.williams@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: "Luis Claudio R.

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.

2008-06-04[libata] ACPI: Properly handle bay devices in dock stationsHolger Macht
* Differentiate between bay devices in dock stations and others: - When an ACPI_NOTIFY_EJECT_REQUEST appears, just signal uevent to userspace (that is when the optional eject button on a bay device is pressed/pulled) giving the possibility to unmount file systems and to clean up. Also, only send uevent in case we get an EJECT_REQUEST without doing anything else. In other cases, you'll get an add/remove event because libata attaches/detaches the device. - In case of a dock event, which in turn signals an ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it may already have been gone * In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if the device has been plugged or unplugged. If plugged, hotplug it, if unplugged, just signal event to userspace (initial patch by Matthew Garrett <mjg59@srcf.ucam.org>) * Call ACPI _EJ0 for detached devices Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-06-03net: neighbour table ABI problemStephen Hemminger
The neighbor table time of last use information is returned in the incorrect unit. Kernel to user space ABI's need to use USER_HZ (or milliseconds), otherwise the application has to try and discover the real system HZ value which is problematic. Linux has standardized on keeping USER_HZ consistent (100hz) even when kernel is running internally at some other value. This change is small, but it breaks the ABI for older version of iproute2 utilities. But these utilities are already broken since they are looking at the psched_hz values which are completely different. So let's just go ahead and fix both kernel and user space. Older utilities will just print wrong values. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-06-03bluetooth: rfcomm_dev_state_change deadlock fixDave Young
There's logic in __rfcomm_dlc_close: rfcomm_dlc_lock(d); d->state = BT_CLOSED; d->state_changed(d, err); rfcomm_dlc_unlock(d); In rfcomm_dev_state_change, it's possible that rfcomm_dev_put try to take the dlc lock, then we will deadlock. Here fixed it by unlock dlc before rfcomm_dev_get in rfcomm_dev_state_change. why not unlock just before rfcomm_dev_put? it's because there's another problem. rfcomm_dev_get/rfcomm_dev_del will take rfcomm_dev_lock, but in rfcomm_dev_add the lock order is : rfcomm_dev_lock --> dlc lock so I unlock dlc before the taken of rfcomm_dev_lock. Actually it's a regression caused by commit 1905f6c736cb618e07eca0c96e60e3c024023428 ("bluetooth : __rfcomm_dlc_close lock fix"), the dlc state_change could be two callbacks : rfcomm_sk_state_change and rfcomm_dev_state_change. I missed the rfcomm_sk_state_change that time.

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.

2008-05-31kbuild: fix $(src) assignmnet with external modulesSam Ravnborg
When we introduced support for KBUILD_EXTRA_SYMBOLS we started to include the externam module's kbuild file when doing the final modpost step. As external modules often do: ccflags-y := -I$(src) We had problems because $(src) was unassinged and gcc then used the next parameter for -I resulting in strange build failures. Fix is to assign $(src) and $(obj) when building external modules.

2008-05-31[POWERPC] Add "memory" clobber to MMIO accessorsBenjamin Herrenschmidt
Gcc might re-order MMIO accessors vs. surrounding consistent memory accesses, which is a "bad thing", and could break drivers. This fixes it by adding a "memory" clobber to the MMIO accessors, which should prevent gcc from doing that reordering.

2008-05-30atl1: fix 4G memory corruption bugAlexey Dobriyan
When using 4+ GB RAM and SWIOTLB is active, the driver corrupts memory by writing an skb after the relevant DMA page has been unmapped. Although this doesn't happen when *not* using bounce buffers, clearing the pointer to the DMA page after unmapping it fixes the problem. http://marc.info/?t=120861317000005&r=2&w=2 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
