Analyze and fix the following issue in the Linux kernel code: powerpc: Check for valid hugepage size in hugetlb_get_unmapped_area
Problem Details: It looks like most of the hugetlb code is doing the correct thing if hugepages are not supported, but the mmap code is not. If we get into the mmap code when hugepages are not supported, such as in an LPAR which is running Active Memory Sharing, we can oops the kernel. This fixes the oops being seen ...

Problem Details: The 802.11 header is only padded to 32-bit boundary when the frame has a non-zero length payload. In other words, control frames (e.g., ACK) do not have a padding and we should not try to remove it. This fixes monitor mode for short control frames.

Analyze and fix the following issue in the Linux kernel code: nohz: suppress needless timer reprogramming
Problem Details: In my device I get many interrupts from a high speed USB device in a very short period of time. The system spends a lot of time reprogramming the hardware timer which is in a slower timing domain as compared to the CPU. This results in the CPU spending a huge amount of time waiting for the timer post...
