Subject: [PATCH v4 12/21] powerpc/64: add context tracking to asynchronous interrupts
Date: Sat, 2 Jan 2021 22:24:59 +1000 [thread overview]
Message-ID: <20210102122508.1950592-13-npiggin@gmail.com> (raw)
In-Reply-To: <20210102122508.1950592-1-npiggin@gmail.com>
Previously context tracking was not done for asynchronous interrupts,
(those that run in interrupt context), and if those would cause a
reschedule when they exit, then scheduling functions (schedule_user,
preempt_schedule_irq) call exception_enter/exit to fix this up and
exit user context.
This is a hack we would like to get away from, so do context tracking
for asynchronous interrupts too.
