2019-08-21RDMA/odp: Use the common interval tree library instead of genericJason Gunthorpe3-62/+31
ODP is working with userspace VA's in the interval tree which always fit into an unsigned long, so we can use the common code. This comes at a cost of a 16 byte increase in ib_umem_odp struct size due to storing the interval tree start/last in addition to the umem addr/length. However these values were computed and are performance critical for the interval lookup, so this seems like a worthwhile trade off. Removes 2k of .text from the kernel.

Fixed pep8/flake8 python style code for lsvmbus tool. The TAB indentation was on purpose ignored (pep8 rule W191) to make sure the code is complying with the Linux code guideline.

2019-08-16arm64: ftrace: Ensure module ftrace trampoline is coherent with I-sideWill Deacon1-9/+13
The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1bebaf7 ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc83 ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.
