    Subject[PATCH 5.10 514/545] tpm: eventlog: Fix section mismatch for DEBUG_SECTION_MISMATCH
    Date
    From: Huacai Chen <chenhuacai@loongson.cn>

    commit bed4593645366ad7362a3aa7bc0d100d8d8236a8 upstream.

    If DEBUG_SECTION_MISMATCH enabled, __calc_tpm2_event_size() will not be
    inlined, this cause section mismatch like this:

    WARNING: modpost: vmlinux.o(.text.unlikely+0xe30c): Section mismatch in reference from the variable L0 to the function .init.text:early_ioremap()
    The function L0() references
    the function __init early_memremap().
    This is often because L0 lacks a __init
    annotation or the annotation of early_ioremap is wrong.

    Fix it by using __always_inline instead of inline for the called-once
    function __calc_tpm2_event_size().

    Fixes: 44038bc514a2 ("tpm: Abstract crypto agile event size calculations")
