*	[PATCH] Numerous fixes to kernel-doc info in source files.	Robert P. J. Day	2007-02-11
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	A variety of (mostly) innocuous fixes to the embedded kernel-doc content in source files, including: * make multi-line initial descriptions single line * denote some function names, constants and structs as such * change erroneous opening '/' to '/' in a few places reword some text for clarity Signed-off-by: Robert P.

*	[PATCH] x86: SMP alternatives	Gerd Hoffmann	2006-03-23
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Implement SMP alternatives, i.e. switching at runtime between different code versions for UP and SMP. The code can patch both SMP->UP and UP->SMP. The UP->SMP case is useful for CPU hotplug. With CONFIG_CPU_HOTPLUG enabled the code switches to UP at boot time and when the number of CPUs goes down to 1, and switches to SMP when the number of CPUs goes up to 2. Without CONFIG_CPU_HOTPLUG or on non-SMP-capable systems the code is patched once at boot time (if needed) and the tables are released afterwards. The changes in detail: * The current alternatives bits are moved to a separate file, the SMP alternatives code is added there. * The patch adds some new elf sections to the kernel: .smp_altinstructions like .altinstructions, also contains a list of alt_instr structs. .smp_altinstr_replacement like .altinstr_replacement, but also has some space to save original instruction before replaving it. .smp_locks list of pointers to lock prefixes which can be nop'ed out on UP. The first two are used to replace more complex instruction sequences such as spinlocks and semaphores. It would be possible to deal with the lock prefixes with that as well, but by handling them as special case the table sizes become much smaller. * The sections are page-aligned and padded up to page size, so they can be free if they are not needed. * Splitted the code to release init pages to a separate function and use it to release the elf sections if they are unused.

*	[PATCH] mark several functions __always_inline	Ingo Molnar	2006-01-14
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Arjan van de Ven <arjan@infradead.org> Mark a number of functions as 'must inline'. The functions affected by this patch need to be inlined because they use knowledge that their arguments are constant so that most of the function optimizes away. At this point this patch does not change behavior, it's for documentation only (and for future patches in the inline series) Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

*	[PATCH] x86: fls() in asm	Stephen Hemminger	2006-01-06
\| \| \| \| \| \| \| \| \|	There is a single instruction on i386 to find largest set bit; so it makes sense to use it (like we use bfs for ffs()). Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-16
	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!
