kallsyms: lower alignment on ARM
As mentioned in the info pages of gas, the '.align' pseudo op's interpretation of the alignment value is architecture specific. It might either be a byte value or taken to the power of two. On ARM it's actually the latter which leads to unnecessary large alignments of 16 bytes for 32 bit builds or 256 bytes for 64 bit builds. Fix this by switching to '.balign' instead which is consistent across all architectures. Signed-off-by: Mathias Krause <> Cc: Catalin Marinas <> Cc: Will Deacon <> Signed-off-by: Masahiro Yamada <>
