<div class='commit-subject'>crypto: testmgr - Use heap buffer for acomp test input</div><div class='commit-msg'>Christopher Covington reported a crash on aarch64 on recent Fedora

The test vectors used for input are part of the kernel image. These
inputs are passed as a buffer to sg_init_one which eventually blows up
with BUG_ON(!virt_addr_valid(buf)). On arm64, virt_addr_valid returns
false for the kernel image since virt_to_page will not return the
correct page. Fix this by copying the input vectors to heap buffer
before setting up the scatterlist.
