2009-04-22sparc: Fix bus type probing for ESP and LE devices.David S. Miller
If there is a dummy "espdma" or "ledma" parent device above ESP scsi or LE ethernet device nodes, we have to match the bus as SBUS. Otherwise the address and size cell counts are wrong and we don't calculate the final physical device resource values correctly at all. Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling of LANCE and ESP parent nodes in of_device.c") was meant to fix this problem, but that only influences the inner loop of build_device_resources(). We need this logic to also kick in at the beginning of build_device_resources() as well, when we make the first attempt to determine the device's immediate parent bus type for 'reg' property element extraction. Based almost entirely upon a patch by Friedrich Oslage. Tested-by: Meelis Roos <mroos@linux.ee> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-04-01generic debug pageallocAkinobu Mita
CONFIG_DEBUG_PAGEALLOC is now supported by x86, powerpc, sparc64, and s390. This patch implements it for the rest of the architectures by filling the pages with poison byte patterns after free_pages() and verifying the poison patterns before alloc_pages(). This generic one cannot detect invalid page accesses immediately but invalid read access may cause invalid dereference by poisoned memory and invalid write access can be detected after a long delay.

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
