USB: update documentation for usbmon 2012-01-12T19:35:06+00:00 Alan Stern stern@rowland.harvard.edu 2012-01-04T21:36:35+00:00 90a043b02598d19b6dccc677bbf9bb8e8ec94ab7 commit d8cae98cddd286e38db1724dda1b0e7b467f9237 upstream. The documentation for usbmon is out of date; the usbfs "devices" file now exists in /sys/kernel/debug/usb rather than /proc/bus/usb. This patch (as1505) updates the documentation accordingly, and also mentions that the necessary information can be found by running lsusb.

PM / Runtime: Automatically retry failed autosuspends 2011-11-11T17:36:57+00:00 Alan Stern stern@rowland.harvard.edu 2011-11-03T22:39:18+00:00 8dc9c7911421d8e45901ffaf483b5dca99cbb055 commit 886486b792e4f6f96d4fbe8ec5bf20811cab7d6a upstream. Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. Therefore this patch (as1492) adds a mechanism for retrying failed autosuspends. If the callback routine updates the last_busy field so that the next autosuspend expiration time is in the future, the autosuspend will automatically be rescheduled.

whenever a suspend attempt failed.  The idle callback routine could
then schedule a delayed suspend for some time later.

However this behavior was changed by commit

there was no clear mechanism to retry failed suspends.

This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down.  Therefore
this patch (as1492) adds a mechanism for retrying failed
autosuspends.  If the callback routine updates the last_busy field so
that the next autosuspend expiration time is in the future, the
autosuspend will automatically be rescheduled.

hwspinlock/core: use a mutex to protect the radix tree 2011-11-11T17:36:31+00:00 Juan Gutierrez jgutierrez@ti.com 2011-09-06T06:30:16+00:00 b323615a633b4ac47834844f330f9cc329aeaf2b commit 93b465c2e186d96fb90012ba0f9372eb9952e732 upstream. Since we're using non-atomic radix tree allocations, we should be protecting the tree using a mutex and not a spinlock. Non-atomic allocations and process context locking is good enough, as the tree is manipulated only when locks are registered/ unregistered/requested/freed. The locks themselves are still protected by spinlocks of course, and mutexes are not involved in the locking/unlocking paths.

lguest: allow booting guest with CONFIG_RELOCATABLE=y 2011-08-17T17:55:53+00:00 Rusty Russell rusty@rustcorp.com.au 2011-08-15T00:45:10+00:00 3438bc96d02ea314a04759e435e50b5b6177f88c commit e22a539824e8ddb82c87b4f415165ede82e6ab56 upstream. The CONFIG_RELOCATABLE code tries to align the unpack destination to the value of 'kernel_alignment' in the setup_hdr. If that's 0, it tries to unpack to address 0, which in fact causes the gunzip code to call 'error("Out of memory while allocating output buffer")'. The bootloader (ie. the lguest Launcher in this case) should be doing setting this field; the normal bzImage is 16M, we can use the same.
