The new style brightness control provides an operating range of 9 values (seems consistent over a large number of models sharing the same brightness control methods). Read and use the minimum and maximum values to limit the backlight interface between those boundaries.

This partially reverts commit e6e1e259. That commit changed the structure layout of the trace structure, which in turn broke PowerTOP (1.9x generation) quite badly. I appreciate not wanting to expose the variable in question, and PowerTOP was not using it, so I've replaced the variable with just a padding field - that way if in the future a new field is needed it can just use this padding field.

We make use of ptrace_get_breakpoints() / ptrace_put_breakpoints() to protect ptrace_set_debugreg() even if CONFIG_HAVE_HW_BREAKPOINT if off. However in this case, these APIs are not implemented. To fix this, push the protection down inside the relevant ifdef. Best would be to export the code inside CONFIG_HAVE_HW_BREAKPOINT into a standalone function to cleanup the ifdefury there and call the breakpoint ref API inside. But as it is more invasive, this should be rather made in an -rc1.

The logic in __get_user_pages() used to skip the stack guard page lookup whenever the caller wasn't interested in seeing what the actual page was. But Michel Lespinasse points out that there are cases where we don't care about the physical page itself (so 'pages' may be NULL), but do want to make sure a page is mapped into the virtual address space. So using the existence of the "pages" array as an indication of whether to look up the guard page or not isn't actually so great, and we really should just use the FOLL_MLOCK bit. But because that bit was only set for the VM_LOCKED case (and not all vma's necessarily have it, even for mlock()), we couldn't do that originally. Fix that by moving the VM_LOCKED check deeper into the call-chain, which actually simplifies many things. Now mlock() gets simpler, and we can also check for FOLL_MLOCK in __get_user_pages() and the code ends up much more straightforward.

The SLUB allocator use of the cmpxchg_double logic was wrong: it actually needs the irq-safe one. That happens automatically when we use the native unlocked 'cmpxchg8b' instruction, but when compiling the kernel for older x86 CPUs that do not support that instruction, we fall back to the generic emulation code. And if you don't specify that you want the irq-safe version, the generic code ends up just open-coding the cmpxchg8b equivalent without any protection against interrupts or preemption. Which definitely doesn't work for SLUB. This was reported by Werner Landgraf <w.landgraf@ru.ru>, who saw instability with his distro-kernel that was compiled to support pretty much everything under the sun. Most big Linux distributions tend to compile for PPro and later, and would never have noticed this problem. This also fixes the prototypes for the irqsafe cmpxchg_double functions to use 'bool' like they should. [ Btw, that whole "generic code defaults to no protection" design just sounds stupid - if the code needs no protection, there is no reason to use "cmpxchg_double" to begin with. So we should probably just remove the unprotected version entirely as pointless. - Linus ] Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Reported-and-tested-by: Nwerner <w.landgraf@ru.ru> Acked-and-tested-by: NIngo Molnar <mingo@elte.hu> Acked-by: NChristoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: Jens Axboe <axboe@kernel.dk> Cc: Tejun Heo <tj@kernel.org> Link: http://lkml.kernel.org/r/alpine.LFD.2.02.1105041539050.3005@ionosSigned-off-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

In particular, s_freeing_list needs to be initialized early, since it is used on some of the error paths when mounts fail. The mapping inode, for example, would be initialized and then free'd on an error path before s_freeing_list was initialized, but the inode drop operation needs the s_freeing_list to be set up. Normally you'd never see this, because not only is logfs fairly rare, but a successful mount will never have any issues.
