2012-05-28edac: Create a dimm struct and move the labels into itMauro Carvalho Chehab
The way a DIMM is currently represented implies that they're linked into a per-csrow struct. However, some drivers don't see csrows, as they're ridden behind some chip like the AMB's on FBDIMM's, for example. This forced drivers to fake^Wvirtualize a csrow struct, and to create a mess under csrow/channel original's concept. Move the DIMM labels into a per-DIMM struct, and add there the real location of the socket, in terms of csrow/channel. Latter patches will modify the location to properly represent the memory architecture. All other drivers will use a per-csrow type of location. Some of those drivers will require a latter conversion, as they also fake the csrows internally. TODO: While this patch doesn't change the existing behavior, on csrows-based memory controllers, a csrow/channel pair points to a memory rank. There's a known bug at the EDAC core that allows having different labels for the same DIMM, if it has more than one rank. A latter patch is need to merge the several ranks for a DIMM into the same dimm_info struct, in order to avoid having different labels for the same DIMM. The edac_mc_alloc() will now contain a per-dimm initialization loop that will be changed by latter patches in order to match other types of memory architectures.

2012-05-28ext4: use consistent ssize_t type in ext4_file_write()Zheng Liu
The generic_file_aio_write() function returns ssize_t, and ext4_file_write() returns a ssize_t, so use a ssize_t to collect the return value from generic_file_aio_write(). It shouldn't matter since the VFS read/write paths shouldn't allow a read greater than MAX_INT, but there was previously a bug in the AIO code paths, and it's best if we use a consistent type so that the return value from generic_file_aio_write() can't get truncated.

2012-05-28ext4: fix potential integer overflow in alloc_flex_gd()Haogang Chen
In alloc_flex_gd(), when flexbg_size is large, kmalloc size would overflow and flex_gd->groups would point to a buffer smaller than expected, causing OOB accesses when it is used. Note that in ext4_resize_fs(), flexbg_size is calculated using sbi->s_log_groups_per_flex, which is read from the disk and only bounded to [1, 31]. The patch returns NULL for too large flexbg_size.

2012-05-27lib: Fix generic strnlen_user for 32-bit big-endian machinesPaul Mackerras
The aligned_byte_mask() definition is wrong for 32-bit big-endian machines: the "7-(n)" part of the definition assumes a long is 8 bytes. This fixes it by using BITS_PER_LONG - 8 instead of 8*7. Tested on 32-bit and 64-bit PowerPC. Signed-off-by: Paul Mackerras <paulus@samba.org> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
