This fixes the problem of not handling the NETDEV_UP event properly during hot-plug or modprobe of bnx2 after cnic. The handling was skipped by mistakenly using "else if" to check for the event. Also update version to 2.0.1. Signed-off-by:

The only error returned by pci_{en,dis}able_pcie_error_reporting() is -EIO which simply means that Advanced Error Reporting is not supported. There is no need to report that, so remove the error check from e1000e, igb and ixgbe. Signed-off-by:Frans Pop <elendil@planet.nl> Signed-off-by:

tcp_splice_read() doesnt take into account socket's O_NONBLOCK flag Before this patch : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE); causes a random endless block (if pipe is full) and splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK); will return 0 immediately if the TCP buffer is empty. User application has no way to instruct splice() that socket should be in blocking mode but pipe in nonblock more. Many projects cannot use splice(tcp -> pipe) because of this flaw. http://git.samba.org/?p=samba.git;a=history;f=source3/lib/recvfile.c;h=ea0159642137390a0f7e57a123684e6e63e47581;hb=HEAD http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0687.html Linus introduced SPLICE_F_NONBLOCK in commit 29e35094 (splice: add SPLICE_F_NONBLOCK flag ) It doesn't make the splice itself necessarily nonblocking (because the actual file descriptors that are spliced from/to may block unless they have the O_NONBLOCK flag set), but it makes the splice pipe operations nonblocking. Linus intention was clear : let SPLICE_F_NONBLOCK control the splice pipe mode only This patch instruct tcp_splice_read() to use the underlying file O_NONBLOCK flag, as other socket operations do. Users will then call : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK ); to block on data coming from socket (if file is in blocking mode), and not block on pipe output (to avoid deadlock) First version of this patch was submitted by Octavian Purdila Reported-by:

When using %*s, sscanf should honor conversion specifiers immediately following the %*s. For example, the following code should find the position of the end of the string "hello". int end; char buf[] = "hello world"; sscanf(buf, "%*s%n", &end); printf("%d\n", end); Ideally, sscanf would advance the fmt and str pointers the same as it would without the *, but the code for that is rather complicated and is not included in the patch.

Allow users to force skipping the TXEN test at init time. Applies to all serial ports. Intended for debugging only. There is a blacklist for devices where we need to skip the test but the list is not complete. This lets users force skipping the test so we can determine if they need to be added to the list. Some HP machines with weird serial consoles have this problem and there may be more. Signed-off-by:

Add better support for omitting either the card detect or the write protect GPIOs if the board does not support it. Add the fields no_wprotect and no_detect to the platform data which when set indicate the absence of the respective GPIOs. Note, this also fixes a minor bug where it tries to free IRQ0 if there is no detect gpio available. Signed-off-by:

We have found a couple of boards where the SDIO IRQ hardware support has failed to work properly, and thus we should make it configurable whether or not to be included in the driver. Signed-off-by:

Fixes for the DMA transfer mode of the driver to try and improve the state of the code: - Ensure that dma_complete is set during the end of the command phase so that transfers do not stall awaiting the completion - Update the DMA debugging to provide a bit more useful information such as how many DMA descriptors where not processed and print the DMA addresses in hexadecimal. - Fix the DMA channel request code to actually request DMA for the S3CMCI block instead of whatever '0' signified. - Add fallback to PIO if we cannot get the DMA channel, as many of the devices with this block only have a limited number of DMA channels. - Only try and claim and free the DMA channel if we are trying to use it. This improves the driver DMA code to the point where it can now identify a card and read the partition table. However the DMA can still stall when trying to move data between the host and memory.

Add a selection for the data transfer mode of the s3cmci driver, allowing for either a configuration or rumtime selection of the use of the DMA or PIO transfer code. The PIO only mode is 476 bytes smaller than the driver with both methods compiled in. Signed-off-by:

The controller supports SDIO IRQ detection so add support for hardware assisted SDIO interrupt detection for the SDIO core. This improves the response time for SDIO interrupts and thus the transfer rate from devices such as the Marvel 8686. As a note, it does seem that the controller will miss an IRQ than is held asserted, so there are some manual checks to see if the SDIO interrupt is active after a transfer. Major testing on the S3C2440. Signed-off-by:
