2010-01-15powerpc/iseries: Initialise on-stack completionMichael Ellerman
get_viotape_info() declares a vio_waitevent on the stack, which contains a completion, but never initialises the completion. I have no idea how this ever worked, and on recent kernels it causes an oops in handle_tape_event() when we access the non-initialised completion.

2010-01-15serial/pmac_zilog: Workaround problem due to interrupt on closed portBenjamin Herrenschmidt
It seems that in qemu, we can see an interrupt in R3 despite the fact that it's masked in W1. The chip doesn't actually issue an interrupt, but we can "see" it when taking an interrupt for the other channel. This may be a qemu bug ... or not, so let's be safe and avoid calling into the UART layer when that happens which woulc cause a crash.

2010-01-15powerpc/macintosh: Make Open Firmware device id constantMárton Németh
The match_table field of the struct of_device_id is constant in <linux/of_platform.h> so it is worth to make the initialization data also constant.

Make sure compiler won't do weird things with limits. E.g. fetching them twice may return 2 different values after writable limits are implemented. I.e. either use rlimit helpers added in 3e10e716abf3c71bdb5d86b8f507f9e72236c9cd or ACCESS_ONCE if not applicable.

2010-01-15powerpc: cpumask_of_node() should handle -1 as a nodeAnton Blanchard
pcibus_to_node can return -1 if we cannot determine which node a pci bus is on. If passed -1, cpumask_of_node will negatively index the lookup array and pull in random data: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus 00000000,00000003,00000000,00000000 # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 64-65 Change cpumask_of_node to check for -1 and return cpu_all_mask in this case: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus ffffffff,ffffffff,ffffffff,ffffffff # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 0-127 Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2010-01-15drm/nouveau: check pushbuffer bounds in ioctlLuca Barbieri
Currently there is no check that the pushbuffer request bounds are inside the TTM BO. This allows to instruct the kernel to do relocations on user-selected addresses, since the relocation bounds checking relies on the request bounds. This can oops the kernel accidentally and is easily exploitable. This patch adds bound checking and alignment checking for ->offset and ->nr_dwords. It also makes some variables unsigned, which should have no effect, but prevents possible bounds checking problems.

2010-01-14fix autofs/afs/etc. magic mountpoint breakageAl Viro
We end up trying to kfree() nd.last.name on open("/mnt/tmp", O_CREAT) if /mnt/tmp is an autofs direct mount. The reason is that nd.last_type is bogus here; we want LAST_BIND for everything of that kind and we get LAST_NORM left over from finding parent directory. So make sure that it *is* set properly; set to LAST_BIND before doing ->follow_link() - for normal symlinks it will be changed by __vfs_follow_link() and everything else needs it set that way.

2010-01-14drm/nouveau: trust init table registers are safeBen Skeggs
Apparently the original reason for checking this was there were known register accesses that caused hangs on some chipsets. This was more than likely because of incorrect parsing of previous opcodes, and I hardly think aborting a script half way through is going to be any better (in fact, we have had bug reports where this has been the cause of s/r failures among other things). This patch (which has been in Fedora 12 for a long time now) removes all checking for known register ranges, and just leaves the check to ensure the access is within the mapped aperture to avoid an oops.
