This adds a page flipping ioctl to the KMS API. The ioctl takes an fb ID and a ctrc ID and flips the crtc to the given fb at the next vblank. The ioctl returns immediately but the flip doesn't happen until after any rendering that's currently queued up against the new framebuffer is done. After submitting a page flip, any execbuffer involving the old front buffer will block until the flip is completed. Optionally, a vblank event can be generated when the swap eventually happens.

There are a few more macros in drmP.h that are unused; DRM_GET_PRIV_SAREA, DRM_ARRAY_SIZE, and DRM_WAITCOUNT can go away completely. Unfortunately, DRM_COPY is still used in one place, but we can at least move it to where it's used. It's an awful looking macro.. [akpm: fix overeagerness] Signed-off-by:

This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm to return immediately and notify userspace when the specified vblank sequence happens by sending an event back on the drm fd. The event mechanism works with the other flags supported by the ioctls, specifically, the vblank sequence can be specified relatively or absolutely, and works for primary and seconday crtc. The signal field of the vblank request is used to provide user data, which will be sent back to user space in the vblank event. Signed-off-by:

The icache may also contain aliases so we must account for them just like we do when manipulating the dcache. We usually get away with aliases in the icache because the instructions that are read from memory are read-only, i.e. they never change. However, the place where this bites us is when the code has been modified. Signed-off-by:

This fixes an -rc1 regression brought by the commit: 1cf58fa8 ("nilfs2: shorten freeze period due to GC in write operation v3"). Although the patch moved out a function call of nilfs_ioctl_move_blocks() to nilfs_ioctl_clean_segments() from nilfs_ioctl_prepare_clean_segments(), it didn't move corresponding cleanup job needed for the error case. This will move the missing cleanup job to the destination function. Signed-off-by:

This fixes a kernel oops reported by Markus Trippelsdorf in the email titled "[NILFS users] kernel Oops while running nilfs_cleanerd". The oops was caused by a bug of error path in nilfs_ioctl_move_blocks() function, which was inlined in nilfs_ioctl_clean_segments(). nilfs_ioctl_move_blocks checks duplication of blocks which will be moved in garbage collection. But, the check should have be done within nilfs_ioctl_move_inode_block() to prevent list corruption among buffers storing the target blocks. To fix the kernel oops, this moves forward the duplication check before the list insertion. I also tested this for stable trees [2.6.30, 2.6.31]. Reported-by:

On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo() is thrown when the CAN device is registered due to insufficient skb space, as reported by various users. This patch adds the rtnl_link_ops "get_size" to fix the problem. I think this patch is required for more recent kernels as well, even if no WARN_ON dumps are triggered. Maybe we also need "get_xstats_size" for the CAN xstats. Signed-off-by:

So far, CORB/RIRB still remains even if the driver is switched to the single_cmd mode. The specification says that this should be disabled, but I hoped this isn't the case; indeed most devices worked together with CORB/RIRB. However, Poulsbo (US15W) seems problematic with this setup, and it requires to disable CORB/RIRB when single_cmd is used. Now this patch disables CORB/RIRB initialization when the single_cmd mode is used. Also the unsolicited event is disabled because it can't work without RIRB. Reported-and-tested-by:

Fix combine_word problem where first octet is not read properly. The only affected place seems to be the INPUT_TERMINAL type. Before now, sound controls can be created with the output terminal's name which is a fallback mechanism used only for unknown input terminal types. For example, Line can wrongly appear as Speaker. After the change it should appear as Line. The side effect of this change can be that users can expect the wrong control name in their scripts or programs while now we return the correct one. Probably, these defines should use get_unaligned_le16 and friends. Signed-off-by:

RFC 2003 requires the outer header to have DF set if DF is set on the inner header, even when PMTU discovery is off for the tunnel. Our implementation does exactly that. For this to work properly the IPIP gateway also needs to engate in PMTU when the inner DF bit is set. As otherwise the original host would not be able to carry out its PMTU successfully since part of the path is only visible to the gateway. Unfortunately when the tunnel PMTU discovery setting is off, we do not collect the necessary soft state, resulting in blackholes when the original host tries to perform PMTU discovery. This problem is not reproducible on the IPIP gateway itself as the inner packet usually has skb->local_df set. This is not correctly cleared (an unrelated bug) when the packet passes through the tunnel, which allows fragmentation to occur. For hosts behind the IPIP gateway it is readily visible with a simple ping. This patch fixes the problem by performing PMTU discovery for all packets with the inner DF bit set, regardless of the PMTU discovery setting on the tunnel itself. Signed-off-by:
