2011-01-05[S390] kprobes: coding styleMartin Schwidefsky1-34/+34
Correct some minor coding style issues. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
2011-01-05[S390] kprobes: instruction fixupMartin Schwidefsky2-78/+57
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 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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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 <schwidefsky@de.ibm.com>
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: stable@kernel.org Signed-off-by: Felix Beck <felix.beck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2011-01-05sparc: 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.

The key documentation is slightly out of date, fix that. Also, the list entry in the key struct is no longer used that way, so list_del_init() isn't necessary any more there.

2011-01-04mac80211: serialize rx path workersChristian Lamparter3-43/+49
This patch addresses the issue of serialization between the main rx path and various reorder release timers. <http://www.spinics.net/lists/linux-wireless/msg57214.html> It converts the previously local "frames" queue into a global rx queue [rx_skb_queue]. This way, everyone (be it the main rx-path or some reorder release timeout) can add frames to it. Only one active rx handler worker [ieee80211_rx_handlers] is needed. All other threads which have lost the race of "runnning_rx_handler" can now simply "return", knowing that the thread who had the "edge" will also take care of their workload.
