extern should not appear in C files. Also, the definitions do not match the prototype currently, not sure what way you want to go with this, I've switched the prototype to return int, but I can see going to the void return as well. Signed-off-by:

When the GART table is unmapped from the kernel direct mappings during early bootup, make sure we have no leftover cachelines in it. Note: the clflush done by set_memory_np() was not enough, because clflush does not work on unmapped pages. Signed-off-by:

This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

RCU style multiple probes support for the Linux Kernel Markers. Common case (one probe) is still fast and does not require dynamic allocation or a supplementary pointer dereference on the fast path. - Move preempt disable from the marker site to the callback. Since we now have an internal callback, move the preempt disable/enable to the callback instead of the marker site. Since the callback change is done asynchronously (passing from a handler that supports arguments to a handler that does not setup the arguments is no arguments are passed), we can safely update it even if it is outside the preempt disable section. - Move probe arm to probe connection. Now, a connected probe is automatically armed. Remove MARK_MAX_FORMAT_LEN, unused. This patch modifies the Linux Kernel Markers API : it removes the probe "arm/disarm" and changes the probe function prototype : it now expects a va_list * instead of a "...". If we want to have more than one probe connected to a marker at a given time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it, connecting a second probe handler to a marker will fail. It allow us, for instance, to do interesting combinations : Do standard tracing with LTTng and, eventually, to compute statistics with SystemTAP, or to have a special trigger on an event that would call a systemtap script which would stop flight recorder tracing.

This leads to .config hilarity, with net suddenly ending up in the SCSI menu: # # SCSI device support # # CONFIG_SCSI_DMA is not set # CONFIG_SCSI_NETLINK is not set CONFIG_PPP=y # CONFIG_PHONE is not set Curiously the SLHC select from PPP doesn't seem to happen, as there's no CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug?

On alpha, ia64 and ppc64 only relocations to local data can go into read-only sections. The vast majority of module parameters use the global generic param_set_*/param_get_* functions, so the 'const' attribute for struct kernel_param is not only useless, but it also causes compile failures due to 'section type conflict' in those rare cases where param_set/get are local functions.

Commit d3d74453 ("hrtimer: fixup the HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since only Russell bothered to merge the fix, and Greg to ACK his arch, I'm sending this for merger. I have confirmation that the Alpha bit results in a booting kernel. That leaves: blackfin, frv, sh and sparc untested. The deadlock in question was found by Russell: IRQ handle -> timer_tick() - xtime seqlock held for write -> update_process_times() -> run_local_timers() -> hrtimer_run_queues() -> hrtimer_get_softirq_time() - tries to get a read lock Now, Thomas assures me the fix is trivial, only do_timer() needs to be done under the xtime_lock, and update_process_times() can savely be removed from under it.

The raw_pci_read() interface (as the raw_pci_ops->read() before it) unconditionally fills in a 32-bit integer return value regardless of the size of the operation requested. So claiming to take a "void *" is wrong, as is passing in a pointer to just a byte variable. Noticed by pageexec when enabling -fstack-protector (which needs other patches too to actually work, but that's a separate issue). Acked-by:
