irqchip/gic-v4.1: Avoid 64bit division for the sake of 32bit ARM
In order to allow the GICv4 code to link properly on 32bit ARM, make sure we don't use 64bit divisions when it isn't strictly necessary. Fixes: 4e6437f12d6e ("irqchip/gic-v4.1: Ensure L2 vPE table is allocated at RD level") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Zenghui Yu <yuzenghui@huawei.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
