[PATCH 0/3] riscv: mm: Use hint address in mmap if available

by Charlie Jenkins

On riscv, mmap currently returns an address from the largest address space that can fit entirely inside of the hint address. This makes it such that the hint address is almost never returned. This patch raises the mappable area up to and including the hint address. This allows mmap to often return the hint address, which allows a performance improvement over searching for a valid address as well as making the behavior more similar to other architectures.

[PATCH bpf-next v4 0/3] Fix make install target for BPF selftests

From: Björn Töpel <bjorn(a)rivosinc.com> Here's the fourth try. The "make install" target for the BPF selftests are missing a bunch of files, which makes the BPF machine flavor fail (e.g. cpuv4). This series aims to fix that, but explicitly installing bpftool, all the BPF programs, and the utilities defined by the TRUNNER_EXTRA_PROGS for test_progs. The fact that this series even have a changelog says a lot, but for those who care: v4: Added bpftool v3: Do not use hardcoded file names (Andrii) v2: Added btf_dump_test_case files Björn Töpel (3): selftests/bpf: Remove incorrect object path selftests/bpf: Make install target copy test_progs extra files selftests/bpf: Make install target copy bpftool tools/testing/selftests/bpf/Makefile | 31 +++++++++++++++++----------- 1 file changed, 19 insertions(+), 12 deletions(-) base-commit: beb53f32698ff9cd0ca442c1f856ea0ecfb82be3 -- 2.40.1
