--- Comment #2 from Will Deacon <will at kernel dot org> --- Sorry to nag, but there's a discussion on LKML [1] about reducing the use of the __always_inline attribute in favour of deferring inlining decisions to the compiler. However, without an understanding of the root cause of this issue, I'm very nervous about such a proposal for AArch64 targets. Did you manage to get to the bottom of this issue, so that we can figure out whether it could occur more widely or not (e.g. for 32-bit ARM or for register variables used elsewhere)?
