Add a driver for the Xilinx uartlite serial controller used in boards with the PPC405 core in the Xilinx V2P/V4 fpgas. The hardware is very simple (baudrate/start/stopbits fixed and no break support). See the datasheet for details: http://www.xilinx.com/bvdocs/ipcenter/data_sheet/opb_uartlite.pdf See http://thread.gmane.org/gmane.linux.serial/1237/ for the email thread. Signed-off-by:

check_partition() stops its probe once it hits an I/O error from the partition checkers. This would prevent the actual partition checker getting a chance to verify the partition. So this patch lets check_partition() continue probing untill it hits a success while recording the I/O error which might have been reported by the checking routines. Also, it does some cleanup of the partition methods for ibm, atari and amiga to return -1 upon hitting an I/O error. Signed-off-by:

The current rescan_partition implementation ignores the errors that comes from the lower layer. It reports success for unknown partitions as well as I/O error cases while reading the partition information. The unknown partition is not (and will not be) considered as an error in the kernel, since there are legal users of it (e.g, members of a RAID5 MD Device or a new disk which is not partitioned at all ). Changing this behaviour would scare the user about a serious problem with their disk and is not recommended. Thus for both "unknown partitions" to the Linux (eg., DEC VMS,Novell Netware) and the legal users of NULL partition, would still be reported as "SUCCESS". The patch attached here, scares the user about something which he does need to worry about. i.e, returning -EIO on disk I/O errors while reading the partition information. Signed-off-by:

Remove #define NR_CMDS and replace it w/hba[i]->nr_cmds. Most Smart Array controllers can support up to 1024 commands but the E200 family can only support 128. To prevent annoying "fifo full" messages we define nr_cmds on a per controller basis by adding it the product table. Signed-off-by:

Change the cciss version number to 3.6.14 to reflect the following functionality changes added by the rest of the set. They include: - Support to fire up on any HP RAID class controller - Increase nr_cmds to 512 for most controllers by adding it to the product table - PCI subsystem ID fix fix was pulled - Disable DMA prefetch for the P600 on IPF platforms - Change from 512 to 2048 sector_size for performance - Fix in cciss_open for consistency - Remove the no longer used revalidate_allvol function - Bug fix for busy configuring - Support for more than 16 logical volumes - Cleanups in cciss_interrupt_mode - Fix for iostats, it's been broken for several kernel releases Signed-off-by:

When the UML network driver generates random MACs for its devices, it was possible for a number of UMLs to get the same MACs because the ethernet initialization was done before the random pool was properly seeded. This patch moves the initialization later so that it gets better randomness. Signed-off-by:

Modify process thawing so that we can thaw kernel space without thawing userspace, and thaw kernelspace first. This will be useful in later patches, where I intend to get swsusp thawing kernel threads only before seeking to free memory. Signed-off-by:

Minor whitespace and formatting modifications for the freezer. Signed-off-by:

Nigel Cunningham authored
The freezer currently prints an '=' for every process that is frozen. This is pretty pointless, as the equals sign says nothing about which process is frozen, and makes logs look messier (especially if there were a large number of processes running). All we really need to know is that we started trying to freeze processes and what processes (if any) failed to freeze, or that we succeeded. Signed-off-by:

At some point after 2.6.13, in-kernel software suspend got "incomplete" for the so-called "platform" mode. pm_ops->prepare() is never called. A visible sign of this is the "moon" light on thinkpads not flashing during suspend. Fix by readding the pm_ops->prepare call during suspend. Signed-off-by:
