ARM: net: bpf: improve 64-bit ALU implementation
Improbe the 64-bit ALU implementation from:
movw r8, #65532
movt r8, #65535
movw r9, #65535
movt r9, #65535
ldr r7, [fp, #-44]
adds r7, r7, r8
str r7, [fp, #-44]
ldr r7, [fp, #-40]
adc r7, r7, r9
str r7, [fp, #-40]
to:
movw r8, #65532
movt r8, #65535
movw r9, #65535
movt r9, #65535
ldrd r6, [fp, #-44]
adds r6, r6, r8
adc r7, r7, r9
strd r6, [fp, #-44]
