4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tony Lindgren <[email protected]> [ Upstream commit fe27f16794f313f5fc16f6d2f42d8c2b2f4d70cc ] HS omaps use irq_save_secure_context() instead of irq_save_context() so sar_base will never get initialized and irq_sar_clear() gets called with a wrong address for HS omaps from irq_restore_context(). Starting with commit f4b9f40ae95b ("ARM: OMAP4+: Initialize SAR RAM base early for proper CPU1 reset for kexec") we have it available, and this ideally would been fixed with that commit already.
