This allows for much better abstraction and separation of the XIP and non-XIP cases with their own specific implementations. This fixes the case where a timeout was tripped on in the XIP case by the code that was meant for the non-XIP case only. This also makes for a nice code reduction. Signed-off-by:

The patch below fixes a potential starvation issue that can arise when there is contention on a chip during a period when a process is currently writing to it. The starvation is avoided by conditionally rescheduling when the chip is left in a state usable by other processes. Signed-off-by:

We have to pack at least the jint16_t structure, because otherwise it'll be four bytes in size. Thankfully, we can do that and _not_ pack the actual node structures, and the compiler still doesn't emit stupid code. Signed-off-by: -

On AMD Au1550 the static bus controller fails to keep -CE asserted during chip ready delay on read commands and the NAND chip being used requires this. So, the current driver allows nand_base.c to drive -CE manually during the entire sector read. When the PCMCIA driver is enabled however, occasionally the ECC errors occur on NAND reads. This happens because the PCMCIA driver polls sockets periodically and reads one of the board's control/status regs (BCSRs) which are on the same static bus as the NAND flash, and just use another chip select (and the NOR flash also resides on that bus), so as the NAND driver forces NAND chip select asserted and the -RE signal is shared, a contention occurs on the static bus when BCSR or NOR flash is read while we're reading from NAND. So, we either can't keep interrupts enabled during the whole NAND sector read (which is hardly acceptable), or have to implement some interlocking scheme between multiple drivers (which is painful, and makes me shudder :-). There's a third way which has proven to work: to force -CE asserted only while we're waiting for a NAND chip to become ready after a read command, disabling interrupts for a maximum of 25 microseconds (according to Toshiba TC58DVM92A1FT00 datasheet -- this chip is mentioned in the board schematics); for Samsung NAND chip which seems to be actually used this delay is even less, 12 us.

During the last cleanup of the AMD Au1550 NAND driver the old buglet was reintroduced: as the MEM_STNDCTL register is write-only and seem to always read as 0x31, read-modify-write to it done in au1xxx_nand_init() will have the side effect of enabling -RCS0/1 pin override (via bits 4/5 of this reg.), thus possibly causing a contention on the static bus when the NOR flash (using -RCS0) or board control status registers (using -RCS2) are read. Luckily, this goes away with a first NAND access, since au1550_hwcontrol() doesn't try to read this register before writing anymore. Signed-off-by: -

When we fail to mount from a valid root device list out the filesystems we have tried to mount it with. This gives the user vital diagnostics as to what is missing from their kernel. For example in the fragment below the kernel does not have CRAMFS compiled into the kernel and yet appears to recognise it at the RAMDISK detect stage. Later the mount fails as we don't have the filesystem. RAMDISK: cramfs filesystem found at block 0 RAMDISK: Loading 1604KiB [1 disk] into ram disk... done. XFS: bad magic number XFS: SB validate failed No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat iso9660 jfs xfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1) Signed-off-by:Andy Whitcroft <apw@shadowen.org> Signed-off-by:

can_share_swap_page() is used to check if the page has the last reference. This avoids allocating a new page for COW if it's the last page. However, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0, thus always causes a copy for the last COW page. The below simple patch fixes it. Signed-off-by:

Multiple races can happen when v9fs is interrupted by a signal and Tflush message is sent to the server. After v9fs sends Tflush it doesn't wait until it receives Rflush, and possibly the response of the original message. This behavior may confuse v9fs what fids are allocated by the file server. This patch fixes the races and the fid allocation. Signed-off-by:
