    Subject[PATCH 4.19 61/89] ARC: define __ALIGN_STR and __ALIGN symbols for ARC
    Date
    From: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

    commit 8d92e992a785f35d23f845206cf8c6cafbc264e0 upstream.

    The default defintions use fill pattern 0x90 for padding which for ARC
    generates unintended "ldh_s r12,[r0,0x20]" corresponding to opcode 0x9090

    So use ".align 4" which insert a "nop_s" instruction instead.
