arm_mpam: Force __iomem casts
Code allocates standard kernel memory to pass to the MPAM, which expects
__iomem. The code is safe, because __iomem accessors should work fine
on kernel mapped memory, however leads to sparse warnings:
test_mpam_devices.c:327:42: warning: incorrect type in initializer (different address spaces)
test_mpam_devices.c:327:42: expected char [noderef] __iomem *buf
test_mpam_devices.c:327:42: got void *
test_mpam_devices.c:342:24: warning: cast removes address space '__iomem' of expression
Cast the pointer to memory via __force to silence them.
