[Qemu-devel] [PULL 3/4] Fix corruption of CPSR when SCTLR.EE is set

[Peter Maydell <peter.maydell@linaro.org>]

From: Julian Brown <julian@codesourcery.com>

Fix a typo in arm_cpu_do_interrupt_aarch32 (OR'ing with ~CPSR_E
instead of CPSR_E) which meant that when we took an interrupt with
SCTLR.EE set we would corrupt the CPSR.
