Subject: [PATCH 0/2] Fix secondary CPU boot for thumb2 kernels
Date: Wed, 21 Jan 2015 11:48:16 -0800	[thread overview]
Message-ID: <1421869698-27341-1-git-send-email-sboyd@codeaurora.org> (raw)

Currently I can't boot up secondary CPUs on qcom platforms when I
compile the kernel for THUMB2 mode. This is because we always enter
the kernel in ARM mode regardless of what mode the kernel is compiled
for. This patchset adds a small wrapper to secondary_startup() called
secondary_startup_arm() that allows us to switch into THUMB2 mode if
we need to. If the kernel is compiled for ARM mode it shouldn't have
any effect.

  ARM: Add a secondary_startup that assumes ARM mode
  ARM: qcom: Use secondary_startup_arm()
