Hi all,
This is a minor patch that fixes the entry for the fp16fml feature in
GCC's aarch64-option-extensions.def.
As can be seen in the Linux sources here
https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/cpuinfo.c#L69
the correct string is "asimdfhm", not "asimdfml".
Cross-compiled and tested on aarch64-none-linux-gnu.
Is this ok for trunk?
Also, I don't have commit rights, so could someone commit it on my behalf?
Thanks,
Stam Markianos-Wright
