So here is a fix for alpha and a\npatch to reapply commit 55d98e3edeeb17dd8445db27605d2b34f4c3ba85. I\nconfirmed no failure occurs in 100 trials with the alpha fix.\n\nSigned-off-by: Akihiko Odaki \n---\nAkihiko Odaki (2):\n target/alpha: Reset CPU\n Reapply \"rcu: Unify force quiescent state\"\n\n target/alpha/cpu.c | 1 +\n util/rcu.c | 79 +++++++++++++++++++++++++++++++++++-------------------\n 2 files changed, 52 insertions(+), 28 deletions(-)\n---\nbase-commit: ece408818d27f745ef1b05fb3cc99a1e7a5bf580\nchange-id: 20260216-alpha-42072e98d5bd\n\nBest regards,\n-- \nAkihiko Odaki "}
