2011-03-23usb: musb: blackfin: fix typo in platform driver nameMike Frysinger
The modularization of the Blackfin driver set the name to "musb-blackfin" in all the boards, but "musb-bfin" in the driver itself. Since the driver file name uses "blackfin", change the driver to "musb-blackfin". This is also easier as it's only one file to change.

2011-03-23ehci-hcd: Bug fix: don't set a QH's Halt bitAlan Stern
This patch (as1453) fixes a long-standing bug in the ehci-hcd driver. There is no need to set the Halt bit in the overlay region for an unlinked or blocked QH. Contrary to what the comment says, setting the Halt bit does not cause the QH to be patched later; that decision (made in qh_refresh()) depends only on whether the QH is currently pointing to a valid qTD. Likewise, setting the Halt bit does not prevent completions from activating the QH while it is "stopped"; they are prevented by the fact that qh_completions() temporarily changes qh->qh_state to QH_STATE_COMPLETING. On the other hand, there are circumstances in which the QH will be reactivated _without_ being patched; this happens after an URB beyond the head of the queue is unlinked. Setting the Halt bit will then cause the hardware to see the QH with both the Active and Halt bits set, an invalid combination that will prevent the queue from advancing and may even crash some controllers. Apparently the only reason this hasn't been reported before is that unlinking URBs from the middle of a running queue is quite uncommon. However Test 17, recently added to the usbtest driver, does exactly this, and it confirms the presence of the bug. In short, there is no reason to set the Halt bit for an unlinked or blocked QH, and there is a very good reason not to set it. Therefore the code that sets it is removed.

2011-03-23perf: Better fit max unprivileged mlock pages for tools needsFrederic Weisbecker
The maximum kilobytes of locked memory that an unprivileged user can reserve is of 512 kB = 128 pages by default, scaled to the number of onlined CPUs, which fits well with the tools that use 128 data pages by default. However tools actually use 129 pages, because they need one more for the user control page. Thus the default mlock threshold is not sufficient for the default tools needs and we always end up to evaluate the constant mlock rlimit policy, which doesn't have this scaling with the number of online CPUs. Hence, on systems that have more than 16 CPUs, we overlap the rlimit threshold and fail to mmap: $ perf record ls Error: failed to mmap with 1 (Operation not permitted) Just increase the max unprivileged mlock threshold by one page so that it supports well perf tools even after 16 CPUs.

2011-03-23NFSv4.1: add generic layer hooks for pnfs COMMITFred Isaman
We create three major hooks for the pnfs code. pnfs_mark_request_commit() is called during writeback_done from nfs_mark_request_commit, which gives the driver an opportunity to claim it wants control over commiting a particular req. pnfs_choose_commit_list() is called from nfs_scan_list to choose which list a given req should be added to, based on where we intend to send it for COMMIT. It is up to the driver to have preallocated list headers for each destination it may need. pnfs_commit_list() is how the driver actually takes control, it is used instead of nfs_commit_list(). In order to pass information between the above functions, we create a union in nfs_page to hold a lseg (which is possible because the req is not on any list while in transition), and add some flags to indicate if we need to use the pnfs code.

2011-03-23MN10300: gcc 4.6 vs am33 inline assemblyRichard Henderson
GCC 4.6 explicitly represents the MDR register. It may be accessed via the "z" constraint. Perhaps more importantly, it tracks when the MDR register is clobbered and uses the RETF instruction if the incoming value is still valid. Thus it is important to (at least) clobber the MDR register in relevant inline assembly fragments, lest RETF be used incorrectly. The only instances I could find are here. There are reads of the MDR register in kernel/gdb-stub.c, but that's harmless. Although, frankly, __builtin_return_address(0) might be a better thing in those cases. Certainly MDR isn't going to contain anything else that might be useful... Signed-off-by: Richard Henderson <rth@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com>

2011-03-23sys_swapon: fix inode lockingCesar Eduardo Barros
A conflict between 52c50567d8ab ("mm: swap: unlock swapfile inode mutex before closing file on bad swapfiles") and 83ef99befc32 ("sys_swapon: remove did_down variable") caused a double unlock of the inode mutex (once in bad_swap: before the filp_close, once at the end just before returning). The patch which added the extra unlock cleared did_down to avoid unlocking twice, but the other patch removed the did_down variable. To fix, set inode to NULL after the first unlock, since it will be used after that point only for the final unlock. While checking this patch, I found a path which could unlock without locking, in case the same inode was added as a swapfile twice. To fix, move the setting of the inode variable further down, to just before claim_swapfile, which will lock the inode before doing anything else.

Convert the SuperH clocks framework and shared interrupt handling code to using struct syscore_ops instead of a sysdev classes and sysdevs for power managment. This reduces the code size significantly and simplifies it. The optimizations causing things not to be restored after creating a hibernation image are removed, but they might lead to undesirable effects during resume from hibernation (e.g. the clocks would be left as the boot kernel set them, which might be not the same way as the hibernated kernel had seen them before the hibernation).
