[Andrew Morton]

The quilt patch titled
     Subject: kcov: mark in_softirq_really() as __always_inline
has been removed from the -mm tree.  Its filename was
     kcov-mark-in_softirq_really-as-__always_inline.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: kcov: mark in_softirq_really() as __always_inline
Date: Tue, 17 Dec 2024 08:18:10 +0100

If gcc decides not to inline in_softirq_really(), objtool warns about a
function call with UACCESS enabled:

kernel/kcov.o: warning: objtool: __sanitizer_cov_trace_pc+0x1e: call to in_softirq_really() with UACCESS enabled
kernel/kcov.o: warning: objtool: check_kcov_mode+0x11: call to in_softirq_really() with UACCESS enabled

Mark this as __always_inline to avoid the problem.
