On ARCH_BRCMSTB using 32-bit and 64-bit ARM kernels, build tested on 
BMIPS_GENERIC:

There is a new warning showing up with 
b27e16c9e625465fe9ea9955bd8ab095498de9e3 ("tcp: fix 
tcp_tso_should_defer() vs large RTT") , but since 5.4 does not have the 
full minmax backports this is expected:

I don't think this should hold off the release though.
