Commit 05b016ecf5e7a "ARC: Setup Vector Table Base in early boot" moved the Interrupt vector Table setup out of arc_init_IRQ() which is called for all CPUs, to entry point of boot cpu only, breaking booting of others. Fix by adding the same to entry point of non-boot CPUs too. read_arc_build_cfg_regs() printing IVT Base Register didn't help the casue since it prints a synthetic value if zero which is totally bogus, so fix that to print the exact Register. [vgupta: Remove the now stale comment from header of arc_init_IRQ and also added the commentary for halt-on-reset] Cc: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Cc: <stable@vger.kernel.org> #3.11 Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
