Sometimes when we crash, current is not valid, (has been written over), so the existing code causes a invalid read during exception context - which is a unrecoverable double fault. This fixes this.

Since r3658 | vapier | 2007-09-12 16:26:11 +0200 (Wed, 12 Sep 2007) | 1 line add more common defines for output sections we've had a new line, NOTES, in our linker script, which causes upstream binutils to complain about "missing phdr". Currently the only other arch that uses NOTES is i386, and the patch which added it also added PHDRS { text PT_LOAD FLAGS(5); /* R_E */ data PT_LOAD FLAGS(7); /* RWE */ note PT_NOTE FLAGS(0); /* ___ */ } and a few other modifications to use ":text" and ":data" to the linker script. It seems that we don't need NOTES at all, so just remove it. Signed-off-by: NBernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: NBryan Wu <cooloney@kernel.org>

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.

This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

Move the init sections to the end of memory so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob.
