Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

oops handling: ensure that any oops is flushed to the mtdoops console This used to work unpatched with older kernels, during the development phase of mtdoops. Before commit e3e8a75d2acfc61ebf25524666a0a2c6abb0620c a space was printed with console_loglevel set to 15, which probably flushed the oops message as a side effect. This is another patch from the Nokia N810 kernel.

[PATCH] Consolidate bust_spinlocks() Part of long forgotten patch http://groups.google.com/group/fa.linux.kernel/msg/e98e941ce1cf29f6?dmode=source Since then, m32r grabbed two copies. Leave s390 copy because of important absence of CONFIG_VT, but remove references to non-existent timerlist_lock. ia64 also loses timerlist_lock.

handle recursive calls to bust_spinlocks() Various architectures may call bust_spinlocks() recursively; the function itself, however, doesn't appear to be meant to be called in this manner. Nevertheless, this doesn't appear to be a problem as long as bust_spinlocks(0) doesn't get called twice in a row (otherwise, unblank_screen() may enter the scheduler). However, at least on i386 die() has been capable of returning (and on other architectures this should really be that way, too) when notify_die() returns NOTIFY_STOP. Short of getting a reply to a respective query, this patch makes bust_spinlocks() increment/decrement oops_in_progress, and wake klogd only when the count drops back to zero.
