2014-12-01rtlwifi: rtl8192ce: Fix editing error that causes silent memory corruptionLarry Finger
In the major update of the rtlwifi-family of drivers, there was an editing mistake. Unfortunately, this particular error leads to memory corruption that silently leads to failure of the system. This patch is one of three needed to fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951.

2014-11-26net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein
Some VF drivers use the upper byte of "param1" (the qp count field) in mlx4_qp_reserve_range() to pass flags which are used to optimize the range allocation. Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.
