2011-01-05[S390] qdio: add qdio interrupts to interrupt statisticsJan Glauber4-0/+8
Count traditional qdio interrupts and adapter interrupts for qdio in the interrupt statistics. Signed-off-by: Jan Glauber <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] irq: have detailed statistics for interrupt typesHeiko Carstens11-20/+56
Up to now /proc/interrupts only has statistics for external and i/o interrupts but doesn't split up them any further. This patch adds a line for every single interrupt source so that it is possible to easier tell what the machine is/was doing. Part of the output now looks like this; CPU0 CPU2 CPU4 EXT: 3898 4232 2305 I/O: 782 315 245 CLK: 1029 1964 727 [EXT] Clock Comparator IPI: 2868 2267 1577 [EXT] Signal Processor TMR: 0 0 0 [EXT] CPU Timer TAL: 0 0 0 [EXT] Timing Alert PFL: 0 0 0 [EXT] Pseudo Page Fault [...] NMI: 0 1 1 [NMI] Machine Checks Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] time: let local_tick_enable/disable() reprogram the clock comparatorHeiko Carstens2-2/+2
Let local_tick_enable/disable() reprogram the clock comparator so the function names make semantically more sense. Also that way the functions are more symmetric since normally each local_tick_enable() call usually would have a subsequent call to set_clock_comparator() anyway. Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] time: move local_tick_enable()/disable() to timex.hHeiko Carstens2-16/+18
Move the two functions to timex.h where they make more sense than in hardirq.h. No functional change. Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>

2011-01-05[S390] kprobes: restructure handler functionMartin Schwidefsky1-43/+71
Restructure the kprobe breakpoint handler function. Add comments to make it more comprehensible and add a sanity check for re-entering kprobes. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: jprobe save and restoreMartin Schwidefsky2-13/+8
Register %r14 and %r15 are already stored in jprobe_saved_regs, no need to store them a second time in jprobe_saved_r14 / jprobe_saved_r15. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: insn slotsMartin Schwidefsky2-10/+1
The s390 architecture can execute code on kmalloc/vmalloc memory. No need for the __ARCH_WANT_KPROBES_INSN_SLOT detour. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: activation and deactivationMartin Schwidefsky1-32/+27
Replace set_current_kprobe/reset_current_kprobe/save_previous_kprobe/ restore_previous_kprobe with a simpler scheme push_kprobe/pop_kprobe. The mini kprobes stack can store up to two active kprobes. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: instruction fixupMartin Schwidefsky2-78/+57

2011-01-05[S390] kprobes: instruction swapMartin Schwidefsky2-12/+9
Move the definition of the helper structure ins_replace_args to the only place where it is used and drop the old member as it is not needed. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: single step cleanupMartin Schwidefsky2-44/+36
The saved interrupt mask and the saved control registers are only relevant while single stepping is set up. A secondary kprobe while kprobe single stepping is active may not occur. That makes is safe to remove the save and restore of kprobe_saved_imask / kprobe_save_ctl from save_previous_kprobe and restore_previous_kprobe. Move all single step related code to two functions, enable_singlestep and disable_singlestep. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] kprobes: single stepped breakpointMartin Schwidefsky1-6/+0
Remove special case of a kprobe on a breakpoint while a relocated instruction is single stepped. The only instruction that may cause a fault while kprobe single stepping is active is the relocated instruction. There is no kprobe on the instruction slot retrieved with get_insn_slot(). Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] cleanup s390 KconfigMartin Schwidefsky7-220/+218
Make use of def_bool and def_tristate where possible and add sensible defaults to the config symbols where applicable. This shortens the defconfig file by another ~40 lines. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-01-05[S390] zcrypt: Fix check to look for facility bits 2 & 65Felix Beck1-1/+1
Fix the check for ap interupts to look for facility bits 2 and 65. Make sure that we only register interrupts for aps, if the machine has ap interrupt support. This patch is relevant only for the 2.6.37 stable series. Cc: [email protected] Signed-off-by: Felix Beck <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>

2011-01-04sparc: fix tftpboot.img for sparc64 on little-endian hostSam Ravnborg3-133/+80
piggyback_32 adapted to support sparc64: - locating "HdrS" differs for sparc and sparc64 - sparc64 updates a_text, a_data + a_bss in the final a.out header Updated Makefile to use piggyback_32 for sparc64. Deleted the now unused piggyback_64.c piggyback_32.c is host endian neutral and works on both little-endian and big-endian hosts. This fixes a long standing bug where sparc64 could not generate tftpboot.img on a x86 host. Signed-off-by: Sam Ravnborg <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2011-01-04sparc: remove obsolete ELF support in piggyback_32.cSam Ravnborg1-22/+5

2011-01-04sparc: use _start for the start entry (like 64 bit does)Sam Ravnborg3-10/+7

2011-01-04sparc: use trapbase in setup_archSam Ravnborg1-2/+1
