When we are in the label cc_dword_align, registers %o0 and %o1 have the same last 2 bits, but it's not guaranteed one of them is zero. So we can get unaligned memory access in label ccte. Example of parameters which lead to this: %o0=0x7ff183e9, %o1=0x8e709e7d, %g1=3 With the parameters I had a memory corruption, when the additional 5 bytes were rewritten. This patch corrects the error. One comment to the patch. We don't care about the third bit in %o1, because cc_end_cruft stores word or less.

In all cases there were a struct of_device_id variable defined __initdata. But it was referenced from struct platform_driver.of_match_table which is not guaranteed to be used during init only. So drop the __initdata annotation.

With AMD cpu family 15h a unit mask was introduced for the Data Cache Miss event (0x041/L1-dcache-load-misses). We need to enable bit 0 (first data cache miss or streaming store to a 64 B cache line) of this mask to proper count data cache misses. Now we set this bit for all families and models. In case a PMU does not implement a unit mask for event 0x041 the bit is ignored.

next_pidmap() just quietly accepted whatever 'last' pid that was passed in, which is not all that safe when one of the users is /proc. Admittedly the proc code should do some sanity checking on the range (and that will be the next commit), but that doesn't mean that the helper functions should just do that pidmap pointer arithmetic without checking the range of its arguments. So clamp 'last' to PID_MAX_LIMIT. The fact that we then do "last+1" doesn't really matter, the for-loop does check against the end of the pidmap array properly (it's only the actual pointer arithmetic overflow case we need to worry about, and going one bit beyond isn't going to overflow).

Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates").

This patch fixes a deadlock in GFS2 where two processes are trying to reclaim an unlinked dinode: One holds the inode glock and calls gfs2_lookup_by_inum trying to look up the inode, which it can't, due to I_FREEING. The other has set I_FREEING from vfs and is at the beginning of gfs2_delete_inode waiting for the glock, which is held by the first. The solution is to add a new non_block parameter to the gfs2_iget function that causes it to return -ENOENT if the inode is being freed.

GFS2 was relying on the writepage code to write out the zeroed data for fallocate. However, with FALLOC_FL_KEEP_SIZE set, this may be past i_size. If it is, it will be ignored. To work around this, gfs2 now calls write_dirty_buffer directly on the buffer_heads when FALLOC_FL_KEEP_SIZE is set, and it's writing past i_size.
