Subject: [ARM] 3472/1: Use the D variants of FLDMIA/FSTMIA on ARMv6
X-Git-Tag: v3.12-rc1~36776^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bb54a335ae6d282a4f177c7b35cd149aa9b0b9be;p=kernel%2Fkernel-generic.git

[ARM] 3472/1: Use the D variants of FLDMIA/FSTMIA on ARMv6

Patch from Catalin Marinas

The X variants are deprecated starting with ARMv6. Using the D variants,
the fpmx_state in vfp_hard_struct is no longer needed.
