2010-06-10omap: GPIO: fix auto-disable of debounce clockKevin Hilman1-0/+1
The addition of the new debounce code (commit 168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of debounce clocks on idle by forgetting to update the debounce clock enable mask. Add back the updating of bank->dbck_enable_mask so debounce clocks are auto-disabled. Signed-off-by: Kevin Hilman <[email protected]> Signed-off-by: Tony Lindgren <[email protected]>
2010-06-10omap: DMTIMER: Ack pending interrupt always when stopping a timerTero Kristo1-3/+3
The kernel timer queue is being run currently from a GP timer running in a one shot mode, which works in a way that when it expires, it will also stop. Usually during this situation, the interrupt handler will ack the interrupt, load a new value to the timer and start it again. During suspend, the situation is slightly different, as we disable interrupts just before timekeeping is suspended, which leaves a small window where the timer can expire before it is stopped, and will leave the interrupt flag pending. This pending interrupt will prevent ARM sleep entry, thus now we ack it always when we are attempting to stop a timer.

2010-06-09x86, irq: Rename gsi_end gsi_top, and fix off by one errorsEric W. Biederman5-14/+14
When I introduced the global variable gsi_end I thought gsi_end on io_apics was one past the end of the gsi range for the io_apic. After it was pointed out the the range on io_apics was inclusive I changed my global variable to match. That was a big mistake. Inclusive semantics without a range start cannot describe the case when no gsi's are allocated. Describing the case where no gsi's are allocated is important in sfi.c and mpparse.c so that we can assign gsi numbers instead of blindly copying the gsi assignments the BIOS has done as we do in the acpi case. To keep from getting the global variable confused with the gsi range end rename it gsi_top. To allow describing the case where no gsi's are allocated have gsi_top be one place the highest gsi number seen in the system. This fixes an off by one bug in sfi.c: Reported-by: jacob pan <[email protected]> This fixes the same off by one bug in mpparse.c: This fixes an off unreachable by one bug in acpi/boot.c:irq_to_gsi Reported-by: Yinghai <[email protected]> Signed-off-by: Eric W.

2010-06-09FRV: Reinstate null behaviour for the GDB remote protocol 'p' commandDavid Howells1-0/+6
Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0dafd ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error.

2010-06-09KVM: MMU: Remove user access when allowing kernel access to gpte.w=0 pageAvi Kivity1-0/+3
If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0. We do that by setting spte.w=1, since the host cr0.wp must remain set so the host can write protect pages. Once we allow write access, we must remove user access otherwise we mistakenly allow the user to write the page.

2010-06-08ARM: 6165/1: trap overflows on highmem pages from kmap_atomic when debuggingNicolas Pitre1-1/+10
When CONFIG_DEBUG_HIGHMEM is used, the fixmap entry used for a highmem page by kmap_atomic() is always cleared by kunmap_atomic(). This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.

2010-06-03xen: ensure timer tick is resumed even on CPU driving the resumeIan Campbell1-2/+2
The core suspend/resume code is run from stop_machine on CPU0 but parts of the suspend/resume machinery (including xen_arch_resume) are run on whichever CPU happened to schedule the xenwatch kernel thread. As part of the non-core resume code xen_arch_resume is called in order to restart the timer tick on non-boot processors. The boot processor itself is taken care of by core timekeeping code. xen_arch_resume uses smp_call_function which does not call the given function on the current processor. This means that we can end up with one CPU not receiving timer ticks if the xenwatch thread happened to be scheduled on CPU > 0. Use on_each_cpu instead of smp_call_function to ensure the timer tick is resumed everywhere.
