...outgoing seizures. BBAC BLOCKED BACKWARD The GP reports the subscriber port with BBAC if a subscriber goes off-hook and does not dial or if a subscriber does not go off-hook during a set-up connenction. After further three minutes the status of this port is changed to BPRM. BPRM BLOCKED PERMANENT When a blocking is set in the partner exchange, but the signaling of the trunk (non-CCS7) is not able to report this blocking, the trunk will be idle in the own exchange. When an outgoing seizure is generated on such a trunk, this seizure will...

Hi Andi, Here's a couple of patches to fix up COMPAT_VDSO: The first is a straightforward implementation of Jan's original idea of relocating the VDSO to match its mapped location. Unlike Jan and Zach's version, I changed it to relocate based on the phdrs rather than the sections; the result is pleasantly compact. The second patch takes advantage of the fact that all the

Hi Andi, Four patches: - clean up asm/bugs.h, by moving all the C code into its own C file - split identify_cpu() into boot and secondary variants, so that boot-time setup functions can be marked __init - repost of the COMPAT_VDSO patches with a bit more robustness from unknown DT_tags, and functions marked __init, since all this is boot-time only setup. Thanks, J --

Currently the blacklist is maintained by hand in kprobes.c which is separated from the function definition and is hard to catch up the kernel update. To solve this issue, I've tried to implement new NOKPROBE_SYMBOL() macro for making kprobe blacklist at build time. Since the NOKPROBE_SYMBOL() macros can be placed right after the function is defined, it is easy to maintain. This series
