Subject: [RFC PATCH v3 00/19] simplify generic cross CPU function call implementation
Date: Thu, 5 Dec 2013 00:12:51 +0800 [thread overview]
Message-ID: <1386173591-28514-1-git-send-email-liuj97@gmail.com> (raw)
Resend for v3.14 merge window. Patch for ARC, MIPS and PARISC has been
merged into v3.13.
Since commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use
logic similar to smp_call_function_single()", single and multiple
(mask version) cross CPU function calls are handled in the same way,
and generic_smp_call_function_interrupt() becomes an aliases of
generic_smp_call_function_single_interrupt(), so only one interrupt
is needed for arch code to support generic SMP function call interfaces.
This patch series simplifies arch code by killing the redundant
interrupt for cross CPU function calls.
We choose to keep generic_smp_call_function_interrupt() instead of
generic_smp_call_function_single_interrupt() because the former is
more generic.
