2011-05-06usb: fix building musb driversAnatolij Gustschin12-73/+74
Commit 3dacdf11 "usb: factor out state_string() on otg drivers" broke building musb drivers since there is already another otg_state_string() function in musb drivers, but with different prototype. Fix musb drivers to use common otg_state_string(), too. Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS is not defined.

2011-05-06Regression: partial revert "tracing: Remove lock_depth from event entry"Arjan van de Ven3-0/+3
This partially reverts commit e6e1e2593592a8f6f6380496655d8c6f67431266. 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.

2011-05-06hw_breakpoints, powerpc: Fix CONFIG_HAVE_HW_BREAKPOINT off-case in ↵Frederic Weisbecker1-4/+11
ptrace_set_debugreg() 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.

2011-05-04VM: skip the stack guard page lookup in get_user_pages only for mlockLinus Torvalds2-8/+4
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.

2011-05-04slub: Fix the lockless code on 32-bit platforms with no 64-bit cmpxchgThomas Gleixner2-3/+3
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 <[email protected]>, 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: Thomas Gleixner <[email protected]> Reported-and-tested-by: werner <[email protected]> Acked-and-tested-by: Ingo Molnar <[email protected]> Acked-by: Christoph Lameter <[email protected]> Cc: Pekka Enberg <[email protected]> Cc: Jens Axboe <[email protected]> Cc: Tejun Heo <[email protected]> Link: http://lkml.kernel.org/r/alpine.LFD.2.02.1105041539050.3005@ionos Signed-off-by: Ingo Molnar <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2011-05-03logfs: initialize superblock entries earlierLinus Torvalds1-4/+4
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.
