2005-11-29IB/mthca: fix posting of send lists of length >= 255 on mem-free HCAsMichael S. Tsirkin
On mem-free HCAs, when posting a long list of send requests, a doorbell must be rung every 255 requests. Add code to handle this. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

If ipoib_ib_dev_up() fails after ipoib_ib_dev_open() is called, then ipoib_ib_dev_stop() needs to be called to clean up. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-11-29IPoIB: don't zero members after we allocate with kzallocRoland Dreier
ipoib_mcast_alloc() uses kzalloc(), so there's no need to zero out members of the mcast struct after it's allocated. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-11-29IPoIB: always set path->query to NULL when query finishesRoland Dreier
Always set path->query to NULL when the SA path record query completes, rather than only when we don't have an address handle. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-28IPoIB: reinitialize path struct's completion for every queryRoland Dreier
It's possible that IPoIB will issue multiple SA queries for the same path struct. Therefore the struct's completion needs to be initialized for each query rather than only once when the struct is allocated, or else we might not wait long enough for later queries to finish and free the path struct too soon.

2005-11-28IB/umad: fix RMPP handlingMichael S. Tsirkin
ib_umad_write in user_mad.c is looking at rmpp_hdr field in MAD before checking that the MAD actually has the RMPP header. So for a MAD without RMPP header it looks like we are actually checking a bit inside M_Key, or something. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Michael S.

2005-11-25NFS: Fix a spinlock recursion inside nfs_update_inode()Trond Myklebust
In cases where the server has gone insane, nfs_update_inode() may end up calling nfs_invalidate_inode(), which again calls stuff that takes the inode->i_lock that we're already holding. In addition, given the sort of things we have in NFS these days that need to be cleaned up on inode release, I'm not sure we should ever be calling make_bad_inode(). Fix up spinlock recursion, and limit nfs_invalidate_inode() to clearing the caches, and marking the inode as being stale. Thanks to Steve Dickson <SteveD@redhat.com> for spotting this.

2005-11-25[PATCH] powerpc: More hugepage boundary case fixesDavid Gibson
Blah. The patch [0] I recently sent fixing errors with in_hugepage_area() and prepare_hugepage_range() for powerpc itself has an off-by-one bug. Furthermore, the related functions touches_hugepage_*_range() and within_hugepage_*_range() are also buggy. Some of the bugs, like those addressed in [0] originated with commit 7d24f0b8a53261709938ffabe3e00f88f6498df9 where we tweaked the semantics of where hugepages are allowed. Other bugs have been there essentially forever, and are due to the undefined behaviour of '<<' with shift counts greater than the type width (LOW_ESID_MASK could return non-zero for high ranges with the right congruences). The good news is that I now have a testsuite which should pick up things like this if they creep in again.

2005-11-24drm: fix quiescent lockingDave Airlie
A fix for a locking bug which is triggered when a client tries to lock with flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock. From: Thomas Hellstrom Signed-off-by: Dave Airlie <airlied@linux.ie>

2005-11-23[PATCH] USB: ohci, move ppc asic tweaks nearer pciDavid Brownell
This should fix a suspend/resume issues that appear with OHCI on some PPC hardware. The PCI layer should doesn't have the hooks needed for such ASIC-specific hooks (in this case, software clock gating), so this moves the code to do that into hcd-pci.c ... where it can be done after the relevant PCI PM state transition (to/from D3).

2005-11-23[PATCH] USB: EHCI updates split init/reinit logic for resumeDavid Brownell
Moving the PCI-specific parts of the EHCI driver into their own file created a few issues ... notably on resume paths which (like swsusp) require re-initializing the controller. This patch: - Splits the EHCI startup code into run-once HCD setup code and separate "init the hardware" reinit code. (That reinit code is a superset of the "early usb handoff" code.) - Then it makes the PCI init code run both, and the resume code only run the reinit code. - It also removes needless pci wrappers around EHCI start/stop methods. - Removes a byteswap issue that would be seen on big-endian hardware. The HCD glue still doesn't actually provide a good way to do all this run-one init stuff in one place though.

2005-11-23[PATCH] USB: EHCI updates mostly whitespace cleanupsDavid Brownell
This cleans up the recent updates to EHCI PCI support: - Gets rid of checks for "is this a PCI device", they're no longer needed since this is now all PCI-only code. - Reduce log spamming: MWI is only interesting in the atypical case that it can actually be used. - Whitespace cleanup, as appropriate for a new file with no other pending patches. So other than that minor logging change, no functional updates.

2005-11-23[PATCH] USB: EHCI updatesDavid Brownell
This fixes some bugs in EHCI suspend/resume that joined us over the past few releases (as usbcore, PCI, pmcore, and other components evolved): - Removes suspend and resume recursion from the EHCI driver, getting rid of the USB_SUSPEND special casing. - Updates the wakeup mechanism to work again; there's a newish usbcore call it needs to use. - Provide simpler tests for "do we need to restart from scratch", to address another case where PCI Vaux was lost. (In this case it was restoring a swsusp snapshot, but there could be others.) Un-exports a symbol that was temporarily exported. A notable change from previous version is that this doesn't move the spinlock init, so there's still a resume/reinit path bug.

2005-11-23[PATCH] PCI: remove bogus resource collision errorRajesh Shah
When attempting to hotadd a PCI card with a bridge on it, I saw the kernel reporting resource collision errors even when there were really no collisions.
