[PATCH] aoe: use ktime_t instead of timeval

From: Tina Ruchandani 'struct frame' uses two variables to store the sent timestamp - 'struct timeval' and jiffies. jiffies is used to avoid discrepancies caused by updates to system time. 'struct timeval' is deprecated because it uses 32-bit representation for seconds

[PATCH] cdrom: always select BLK_SCSI_REQUEST

When CDROM is enabled, but nothing else selects BLK_SCSI_REQUEST, we get this link error: cdrom.c:(.text+0x7a18): undefined reference to `scsi_cmd_blk_ioctl' The problem is that the CDROM helper code has become user-selectable now when it used to only be compiled if anything else enabled it.

[RFC PATCH 1/2] x86: Avoid multiple evaluations in __{get,put}_user_size

Currently __{get,put}_user_size() expand their ptr argument in several places, and some callers pass in expressions with side effects. For example, fs/binfmt_elf.c, passes sp++ as the ptr argument to a chain of __put_user() calls. So far this isn't a problem, as each of these uses is mutually

[RFC PATCH 2/2] x86: Allow paranoid __{get,put}_user

__{get,put}_user calls are designed to be fast and have no checks, relying on the caller to have made the appropriate calls previously. It's very easy to forget a check though, leaving the kernel vulnerable to exploits. Add an option to do the checks and kill the kernel if it catches something

This patch removes the unnecessary index argument from the dsa_dst_add_ds and dsa_dst_del_ds functions and renames them to dsa_tree_add_switch and dsa_tree_remove_switch respectively. In addition to a more explicit scope, we now check the presence of an existing switch with the same index

[PATCH net-next 00/11] net: dsa: parsing stage

When registering a DSA switch, there is basically two stages. The first stage is the parsing of the switch device, from either device tree or platform data. It fetches the DSA tree to which it belongs, and validates its ports. The switch device is then added to the tree, and the second stage is

[PATCH net-next 08/11] net: dsa: rework switch parsing

When parsing a switch, we have to identify to which tree it belongs and parse its ports. Provide two functions to separate the OF and platform data specific paths. Also use the of_property_read_variable_u32_array function to parse the OF member array instead of calling of_property_read_u32_index
