Some architectures require code written to memory as if it were data to be

During resume from hibernate, the snapshot code copies some pages directly,
meaning these architectures do not get a chance to perform their cache
maintenance. Modify the read and decompress code to call
flush_icache_range() on all pages that are restored, so that the restored
in-place pages are guaranteed to be executable on these architectures.

This is fine by me.

Please feel free to add my ACK to it if that helps.

Thanks,
