* x86, hibernate: fix breakage on x86_32 with CONFIG_NUMA setRafael J. Wysocki2008-11-123-0/+43
| | | | | | | | | | | | | | | | | | | | | Impact: fix crash during hibernation on 32-bit NUMA The NUMA code on x86_32 creates special memory mapping that allows each node's pgdat to be located in this node's memory. For this purpose it allocates a memory area at the end of each node's memory and maps this area so that it is accessible with virtual addresses belonging to low memory. As a result, if there is high memory, these NUMA-allocated areas are physically located in high memory, although they are mapped to low memory addresses. Our hibernation code does not take that into account and for this reason hibernation fails on all x86_32 systems with CONFIG_NUMA=y and with high memory present. Fix this by adding a special mapping for the NUMA-allocated memory areas to the temporary page tables created during the last phase of resume. Signed-off-by: Rafael J.

It can be mitigated by limiting read requests to 256 Bytes. This workaround is always enabled for Tbird2 on Gladius. We also add a module parameter to enable workaround for non-Gladius cards.

If more than one path record request is issued, the first completion releases path->done, allowing ipoib_flush_paths() to free the path, and thus corrupting it for the second completion. Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") added the field path->valid and changed the test "if (!path)" to "if (!path || !path->valid)". This change made it possible for a path with an outstanding query to pass the test and issue another query on the same path. Having two queries on the same path leads to a crash.

| * | RDMA/cxgb3: Fix deadlock in iw_cxgb3 (hang when configuring interface)Steve Wise2008-11-122-6/+2

Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | The array wqe->read.reserved has only two entries, but iwch_post_zb_read() sets [0], [1], and [2], which is one too many. This is harmless since it runs into the next field, rem_stag, which is initialized correctly immediately after, but we might as well get things right, especially since it makes the code smaller.

This causes the silent output problem on some Dell laptops. Also, the hp_switch check is screwed up when a line-in or a mic-in jack exists. This is added as an additional output, but hp_switch check doesn't take it into account. This patch fixes these issues: simplify hp_switch check by using the NID instead of bool, and clean up / fix the toggle of HP pins in unsol event handler code.

I found my original email in "sent" folder. The patch in that mail does NOT remove !prev. That change had beed added by someone else. Ok, I think we are not much interested in who did it, let's fix it for good. [ "It looks like this was caused by me fixing rejects.

Ironically, disabling of GPE from interrupt context is already under spinlock, so only userspace needs to start using it.
