2011-01-05[S390] time: move local_tick_enable()/disable() to timex.hHeiko Carstens
Move the two functions to timex.h where they make more sense than in hardirq.h. No functional change. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-01-05[S390] add kprobes annotationsMartin Schwidefsky
Add kprobes annotations to get the massive 'probe kernel.function("*") {}' stress test working. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: coding styleMartin Schwidefsky
Correct some minor coding style issues. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: restructure handler functionMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: jprobe save and restoreMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: insn slotsMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: activation and deactivationMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: instruction fixupMartin Schwidefsky
Determine instruction fixup details in resume_execution, no need to do it beforehand. Remove fixup, ilen and reg from arch_specific_insn. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: instruction swapMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: single step cleanupMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: single stepped breakpointMartin Schwidefsky
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] cleanup s390 KconfigMartin Schwidefsky
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 <schwidefsky@de.ibm.com>

2011-01-04sparc: rename piggyback_32 to piggybackSam Ravnborg

2011-01-04sparc: fix tftpboot.img for sparc64 on little-endian hostSam Ravnborg
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 <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-04sparc: remove obsolete ELF support in piggyback_32.cSam Ravnborg

v2.6.36-rc8-54-gb40827f (x86-32, mm: Add an initial page table for core bootstrapping) made x86 boot using initial_page_table and broke lguest. For 2.6.37 we simply cut & paste the initialization code into lguest (da32dac10126 "lguest: populate initial_page_table"), now we fix it properly by doing that initialization before the paravirt jump.

Add these new power trace events: power:cpu_idle power:cpu_frequency power:machine_suspend The old C-state/idle accounting events: power:power_start power:power_end Have now a replacement (but we are still keeping the old tracepoints for compatibility): power:cpu_idle and power:power_frequency is replaced with: power:cpu_frequency power:machine_suspend is newly introduced. Jean Pihet has a patch integrated into the generic layer (kernel/power/suspend.c) which will make use of it. the type= field got removed from both, it was never used and the type is differed by the event type itself. perf timechart userspace tool gets adjusted in a separate patch.
