The following changes since commit 9443076e4330a14ae2c6114307668b98a8293b77: ARM: p2v: reduce p2v alignment requirement to 2 MiB (2020-10-28 16:59:43 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux.git tags/arm-adrl-replacement-for-v5.11 for you to fetch changes up to aaac3733171fca948c4fb66b78257620e3885339: ARM: kvm: replace open coded VA->PA calculations with adr_l call (2020-10-28 17:05:40 +0100) Change since v1 pull request: - rebase onto v5.10-rc1 + PR 1/2 Cc: Russell King <linux+pull@armlinux.org.uk> Cc: Nicolas Pitre <nico@fluxnic.net> Cc: Linus Walleij <linus.walleij@linaro.org> ---------------------------------------------------------------- Tidy up open coded relative references in asm Use the newly introduced adr_l/ldr_l/str_l/mov_l assembler macros to replace open coded VA-to-PA arithmetic in various places in the code. This avoids the use of literals on v7+ CPUs, reduces the footprint of the code in most cases, and generally makes the code easier to follow.
