From abcee5fb0dfbb248d883a2f6bdb4820abe3ac524 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 8 Sep 2011 09:06:10 +0100 Subject: ARM: SoC: add per-platform SMP operations This adds a 'struct smp_operations' to abstract the CPU initialization and hot plugging functions on SMP systems, which otherwise conflict in a multiplatform kernel. This also helps shmobile and potentially others that have more than one method to do these. To allow the kernel to continue building, the platform hooks are defined as weak symbols which are overrided by the platform code. Once all platforms are converted, the "weak" attribute will be removed and the function made static. Unlike the original version from Marc, this new version from Arnd does not use a generalized abstraction for per-soc data structures but only tries to solve the problem for the SMP operations. This way, we can collapse the previous four data structures into a single struct, which is less systematic but also easier to follow as a causal reader.
