2010-09-24x86/hwmon: register alternate sibling upon CPU removalJan Beulich
Just like pkgtemp registers another core of the same package when one gets removed, coretemp should register another hyperthread (if available) in that situation. As pointed out in the patch fixing the respective code in pkgtemp, the list protectng mutex must be dropped before calling coretemp_device_add(), and due to the restructured loop (including an explicit return) the "safe" variant of the list iterator isn't needed anymore.

2010-09-24x86/hwmon: avoid deadlock on CPU removal in pkgtempJan Beulich
pkgtemp_device_remove(), holding the list protecting mutex, calls pkgtemp_device_add(), which itself wants to acquire the same mutex. Holding the mutex over the entire loop body in pkgtemp_device_remove() isn't really necessary, as long as the loop gets exited after processing the matched CPU. Once exiting the loop after removing an eventual match, there's no need for using the "safe" list iterator anymore.

2010-09-24x86/hwmon: fix module init for hotplug-but-no-device-found caseJan Beulich
In commit 0dca94baeab4a1a514841b0a4c8e3a51dfb4d5ae the call to platform_driver_unregister() was made conditional upon !HOTPLUG_CPU, but the return value from coretemp_init() was left to indicate an error. This isn't correct, as the negative return value indicates to the module loader that initialization failed, which isn't intended here and results in dangling pointers.

2010-09-24usb: musb: host: Issue a memory barrier before starting DMASantosh Shilimkar
This patch fixes the issue which was observed while transfering a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host) to an attached USB thumb drive. It was found that CDB field of CBW packet was set to 0x0. This was due to missing a barrier before DMA engine starts transfer. This buffer is allocated using dma_alloc_coherent which gives non-cacheble but bufferable memory and hence needed a write memory barrier to flush the write buffer.

2010-09-24usb: musb: gadget: enable autoclear for OUT transfer in both DMA 0 and DMA 1Ming Lei
This patch fixes one bugs of OUT transfer in double buffer case: -the current code only enable autoclear for dma mode 1, and not for dma mode 0 Without this patch, test #5 of usbtest can't be passed if we configure musb as g_zero and use fifo mode 3 to enable double buffer mode. With this patch and the following patch(fix dma length), on my beagle B5, test#5(queued bulk out) may go beyond 18Mbyte/s(seems dma mode 0 is quicker in double buffer case) if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8 [1] Also I have tested this patch can't make g_ether broken.

2010-09-24usb: musb: gadget: fix bulk IN infinit hangs in double buffer caseMing Lei
This patch fixes one infinite hang of bulk IN transfer in double buffer case, the hang can be observed easily by test #6 of usbtest if musb is configured as g_zero and fifo mode 3 is taken to enable double fifo. In fact, the patch only removes the check for non-empty fifo before loading data from new request into fifo since the check is not correct: -in double buffer case, fifo may accommodate more than one packet, even though it has contained one packet already and is non-empty -since last DMA is completed before calling musb_g_tx, it is sure that fifo may accommodate at least one packet Without applying the patch, new requst enqueued from .complte may not have a chance to be loaded into fifo, then will never be completed and cause infinite hangs. With the patch, on my beagle B5, test#6(queued bulk in) can be passed and test result may go beyond 33Mbyte/s if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #testusb -D DEV_NAME -c 1024 -t 6 -s 32768 -g 8 [1] [1], -source of testusb : tools/usb/testusb.c under linux kernel; Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Anand Gadiyar <gadiyar@ti.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Anand Gadiyar <gadiyar@ti.com> Cc: Mike Frysinger <vapier@gentoo.org> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-09-24USB: fix bug in initialization of interface minor numbersAlan Stern
Recent changes in the usbhid layer exposed a bug in usbcore. If CONFIG_USB_DYNAMIC_MINORS is enabled then an interface may be assigned a minor number of 0. However interfaces that aren't registered as USB class devices also have their minor number set to 0, during initialization. As a result usb_find_interface() may return the wrong interface, leading to a crash. This patch (as1418) fixes the problem by initializing every interface's minor number to -1. It also cleans up the usb_register_dev() function, which besides being somewhat awkwardly written, does not unwind completely on all its error paths.

In order to support multiple ST platform devices, a new symbol 'st_get_plat_device' earlier needed to be exported by the arch/XX/brd-XX.c file which intends to add the ST platform device. On removing this dependency, now inside ST driver maintain the array of ST platform devices that would be registered. As of now let id=0, as and when we end up having such platforms where mutliple ST devices can exist, id would come from protocol drivers (BT, FM and GPS) as to on which platform device they want to register to.

The "if (!trylock_page)" block in the avoidcopy path of hugetlb_cow() looks confusing and is buggy. Originally this trylock_page() was intended to make sure that old_page is locked even when old_page != pagecache_page, because then only pagecache_page is locked. This patch fixes it by moving page locking into hugetlb_fault().

2010-09-24hugetlb, rmap: use hugepage_add_new_anon_rmap() in hugetlb_cow()Naoya Horiguchi
Obviously, setting anon_vma for COWed hugepage should be done by hugepage_add_new_anon_rmap() to scan vmas faster. This patch fixes it.

2010-09-23o2dlm: force free mles during dlm exitSrinivas Eeda
While umounting, a block mle doesn't get freed if dlm is shutdown after master request is received but before assert master. This results in unclean shutdown of dlm domain. This patch frees all mles that lie around after other nodes were notified about exiting the dlm and marking dlm state as leaving. Only block mles are expected to be around, so we log ERROR for other mles but still free them.

We sync our inode flags with ext2 and define them by hex values. But actually in commit 3669567(4 years ago), all these values are moved to include/linux/fs.h. So we'd better also use them as what ext2 did. So sync our inode flags with ext2 by using FS_*. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

Then I find it is only used if the reservation is empty. ;) So we'd better move it to the parens so that it make the code more readable, what's more, ocfs2_resmap_resv_bits is used so frequently and we should save some cpus.
