| | | | | | | | | | | | | | | | | | ColdFire CPU family members support DMA (all those with the FEC ethernet core use it, the rest have dedicated DMA engines).

| | | | | | | | | | | | | | | | | | | | | | | | | | This processor only have one FEC and its MDIO pins are located at a different offset than the code used for the current CONFIG_M527x. Tesed on M5271EVB eval platform. Without this patch the FEC driver will report no PHY attached if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

To avoid this, let's move the mbus bridge register defines into a separate file and include it where needed. This affects mach-kirkwood, mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all share code in plat-orion which relies on those defines. Some other defines have been moved to narrower scopes, or simply deleted when they had no user. This fixes compilation problem with mpt2sas on the above listed platforms.

The other GPIO113 is not connected to the sound chip, but to the GSM chip as a wakeup line. It happens that when the pxa2xx_ac97 driver reconfigures the gpio as an "out gpio" for AC97 reset (bug workaround), it hangs the GSM chip. As AC97 platform data now enables to specify the AC97 reset line, use it. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>

Obviously this won't actually work when using the generic AC97 driver since the drivers will attempt to parse the platform data in both formats. Fix this by merging the two structures.

These syscalls simply take five long-sized parameters, so they should have no calling-convention/ABI issues in the kernel. Tested on armv5tel eabi using a preadv/pwritev test program posted on linuxppc-dev earlier this month. It would be nice to get this into the kernel before 2.6.30 final, so that glibc's kernel version feature test for these syscalls doesn't have to special-case ARM.

A device's name may not be available after the device is unregistered, even if the device structure itself is still allocated. Since close_backing_file() prints a LUN's name for debugging, it shouldn't be called after the LUN has been unregistered. That whole area needed to be cleaned up; the backing files were getting closed in a couple of different places. The patch fixes things so that they get closed in just one place, as part of the unbind procedure, immediately before the LUN is unregistered.

This can lead to a situation in which the first 188 bytes of a 192-byte isochronous transfer are scheduled in the same uframe as an existing interrupt transfer. The resulting schedule looks like this: uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT uframe 1: 4-byte isoc-OUT SSPLIT The SSPLITs are intermingled, causing an error in the downstream hub's TT. If you are having problems with devices or hub ports resetting, or failed interrupt transfers, when you start using a USB audio or video (Isochronous) device, this patch may help.

The main symptom is that an invalid kevent is created when the serial device is unplugged while a connection is active. Ports should be unregistered when device is disconnected, not when the parent usb_serial structure is deallocated. Each open file should hold a reference to the corresponding port structure, and the reference should be released when the file is closed. serial->disc_mutex should be acquired in serial_open(), to resolve the classic race between open and disconnect. serial_close() doesn't need to hold both serial->disc_mutex and port->mutex at the same time. Release the subdriver's module reference only after releasing all the other references, in case one of the release routines needs to invoke some code in the subdriver module. Replace a call to flush_scheduled_work() (which is prone to deadlocks) with cancel_work_sync(). Also, add a call to cancel_work_sync() in the disconnect routine. Reduce the scope of serial->disc_mutex in serial_disconnect(). The only place it really needs to protect is where the "disconnected" flag is set.

This results in a longer symlink target than if the target value wasn't encrypted. Users were reporting these messages in their syslog: [ 45.653441] ecryptfs_parse_tag_70_packet: max_packet_size is [56]; real packet size is [51] [ 45.653444] ecryptfs_decode_and_decrypt_filename: Could not parse tag 70 packet from filename; copying through filename as-is This was due to bufsiz, one the arguments in readlink(), being used to when allocating the buffer passed to the lower inode's readlink(). That symlink target may be very large, but when decoded and decrypted, could end up being smaller than bufsize. To fix this, the buffer passed to the lower inode's readlink() will always be PATH_MAX in size when filename encryption is enabled. Any necessary truncation occurs after the decoding and decrypting.
