2007-11-09[IA64] Fix IOSAPIC delivery mode settingKenji Kaneshige
Fix the problem that redirect hit bit in I/O SAPIC RTE is set even when it must be disabled (e.g. nointroute boot option is set, CPU hotplug is enabled or percpu vector is enabled). Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2007-11-09[IA64] XPC heartbeat timer function must run on CPU 0Dean Nelson
Currently, XPC's heartbeat timer function runs on whatever CPU modprobe/insmod ran on when XPC was started. To avoid the heartbeat from being delayed for long periods the timer function must run on CPU 0. N.B. Altix doesn't currently allow cpu0 to be taken offline, so this is safe for now. This code must be revised when offline of cpu0 is enabled. Signed-off-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-11-06[IA64] Disable/re-enable CPE interrupts on AltixRuss Anderson
When the CPE handler encounters too many CPEs (such as a solid single bit memory error), it sets up a polling timer and disables the CPE interrupt (to avoid excessive overhead logging the stream of single bit errors). disable_irq_nosync() calls chip->disable() to provide a chipset specifiec interface for disabling the interrupt. This patch adds the Altix specific support to disable and re-enable the CPE interrupt. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-11-06[IA64] Add gate.lds to list of files ignored by GitPeter Chubb

2007-11-06[IA64] Fix section mismatch in contig.c version of per_cpu_init()Tony Luck
There is a section mismatch when building CONFIG_FLATMEM=y kernels that also have CONFIG_HOTPLUG_CPU=y WARNING: vmlinux.o(.text+0x5a902): Section mismatch: reference to \ .init.text:__alloc_bootmem (between 'per_cpu_init' and 'count_pages') The issue occurs because per_cpu_init() in mm/contig.c is marked __cpuinit (which is #define'd to nothing on a hot plug cpu configuration) call __alloc_bootmem() (which is an __init function). The usage is actually safe because the __alloc_bootmem() is inside an "if (first_time)" test so that the call is only made while it is still legal to do so. But the warning is irritating. Move the allocation to find_memory(). Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-11-05[S390] tod clock: announce clocksource as perfectChristian Borntraeger
The Time of Day clock is the standard time source for s390. It is - monotonic - allows very fast reading - architecture guarantees at least microsecond stepping - available as part of the architecture We should announce the rate of tod as 400 to be in sync with the description found in clocksource.h: "400-499:Perfect The ideal clocksource. A must-use where available." This change will prefer tod over less reliable clock sources.

2007-11-05[S390] Fix compile on !CONFIG_SMP.Heiko Carstens
Commit fae8b22d3e3e3a3d317a7746493997af02a3f35c "[S390] Add per-cpu idle time / idle count sysfs attributes" causes a link error on !CONFIG_SMP. Fix this by adding some #ifdef's. Real fix would be to cleanup the code since we don't register a cpu on !CONFIG_SMP. But that would be quite a big patch.

2007-11-02Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle
The Jazz machines have to use the PIT timer for dyntick and highresolution kernels. This may break because currently just like i386 used to do MIPS uses two separate spinlocks in the actual PIT code and the PC speaker code. So switch to do it the same that x86 currently does PIT locking. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
