Since NAPI polling is disabled while ipoib_cm_dev_stop() is running, ipoib_cm_dev_stop() must poll the CQ itself in order to see the packets draining. Signed-off-by:

We need to initialize the owner bit of send queue WQEs to hardware ownership whenever the QP is modified from reset to init, not just when the QP is first allocated. This avoids having the hardware process stale WQEs when the QP is moved to reset but not destroyed and then modified to init again. Signed-off-by:

If a QP is attached to a shared receive queue (SRQ), then it doesn't have a receive queue (RQ). So don't allocate an RQ doorbell (or map a doorbell from userspace for userspace QPs) for that QP. Signed-off-by:

The IB CM uses an idr for local id allocations, with a running counter as start_id. This fails to generate distinct ids if 1. An id is constantly created and destroyed 2. A chunk of ids just beyond the current next_id value is occupied This in turn leads to an increased chance of connection request being mis-detected as a duplicate, sometimes for several retries, until next_id gets past the block of allocated ids. This has been observed in practice. As a fix, remember the last id allocated and start immediately above it. This also fixes a problem with the old code, where next_id might overflow and become negative. Signed-off-by:

SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on and off will, with time, leak out all WRs and then all connections will start getting RNR NAKs. Fix this in the way suggested by spec: move the QP being destroyed to the error state, wait for "Last WQE Reached" event and then post WR on a "drain QP" connected to the same CQ. Once we observe a completion on the drain QP, it's safe to call ib_destroy_qp. Signed-off-by:

This fixes the LDM driver so that it works with Windows Vista dynamic disks which are subtly different to Windows 2000/XP ones. The patch was needed to get a Vista formatted dynamic disk to be recognized and parsed successfully. Thanks go to Chris Teachworth for the report and testing.

The vsyscall time() function basically returns the second portion of xtime directly. This however means that there is about a ticks worth of time each second where time() will return a second value less then what gettimeofday() does. Additionally, this window where vtime() is behind vgettimeofday() grows when dynticks is enabled, so its probably good to get this in before dynticks lands. Big thanks to Sripathi for noticing this issue and creating a test case to work with! This patch changes the vtime() implemenation to call vgettimeofday(), much as syscall time() implementation calls gettimeofday(). 2.6.21 stable candidate too Signed-off-by:

In commit d358788f Author: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Mon Mar 20 20:00:09 2006 +0000 Glen Turner reported that writing LFCR rather than the more traditional CRLF causes issues with some terminals. Since this afflicts many serial drivers, extract the common code to a library function (uart_console_write) and arrange for each driver to supply a "putchar" function. but early_printk is left out.

- boot/setup.S did not print "PANIC: CPU too old for this kernel" ( not visible, also the message did not match ) - I add "# missed before: set ds" => somebody should check if I am right with the way to set. => seems to be a generic error in setup.S not to set "ds" for error messages. AK: extracted patch out of other changes AK: also couldn't find any other case where ds is wrong Signed-off-by:

Only try to allocate MSRs once instead of for every CPU. This assumes the MSRs are the same on all CPUs which is currently true. P4-HT is a special case for different SMT threads, but the code always saves/restores all MSRs so it works identical. Signed-off-by:

There's a forum thread at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741 which has a testcase involving signal handling that crashes quite readily. Inspecting the code I believe what happens is that signal handling can become confused when it is invoked on return from an interrupt, if the contents of P0 and R0 at the time of the interrupt happen to be such that P0 is larger than zero (indicating to the signal code that we're in a syscall), and R0 happens to have a value of something like -EINTR or -ERESTARTSYS. Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The testcase now seems to run without problems. Signed-off-by:
