Instead of storing a pointer to a cdev, embed the entire struct cdev. This change allows us to use the container_of() macro in ib_uverbs_open() in a future patch. This change increases the size of struct ib_uverbs_device to 168 bytes across 3 cachelines from 80 bytes in 2 cachelines. However, we rearrange the members so that everything fits into the first cacheline except for the struct cdev. Finally, we don't touch the cdev in any fastpaths, so this change shouldn't negatively affect performance.

When reserving stack space for a new process, make sure we're not attempting to expand the stack by more than rlimit allows. This fixes a bug caused by b6a2fea3 ("mm: variable length argument support") and unmasked by fc63cf23 ("exec: setup_arg_pages() fails to return errors"). This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg. 80K on 4K pages or 'ulimit -s 79') all processes will be killed before they start. This is particularly bad with 64K pages, where a ulimit below 1280K will kill every process. To test, do: 'ulimit -s 15; ls' before and after the patch is applied. Before it's applied, 'ls' should be killed. After the patch is applied, 'ls' should no longer be killed. A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE. Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle correctly with this code. 4K pages should be fine to test with.

Commit b4846251 ("edac: mpc85xx add mpc83xx support") accidentally broke how a chip select's first and last page addresses are calculated.

This patch fixes a bug in the multiblock write tests where the written data is read back for verifying one block at a time. The tests in mmc_test assumes that all cards are byte addressable. This will cause the multi block write tests to fail, leading the user of the mmc_test driver thinking there is something wrong with the sdhci driver they are testing. The start address for the block is calculated as: blocknum * 512. For block addressable cards the blocknum alone should be used.

This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

Revert the following change from commit 6f8372b6 ("RDMA/cm: fix loopback address support") The defined behavior of rdma_bind_addr is to associate an RDMA device with an rdma_cm_id, as long as the user specified a non- zero address. (ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.
