From 440ee365d30adbcd9a97fba9cd629cedb7e9b7cb Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 30 Oct 2015 21:08:05 +0100 Subject: [PATCH] ARM: 8450/1: v7-M: Use ret_to_user_from_irq in PendSV handler MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The PendSV handler calls v7m_exception_entry which disables IRQs. Therefore, since IRQs are already disabled, the PendSV handler can return using ret_to_user_from_irq.
