Piccoli [ Upstream commit 409dfdcaffb266acfc1f33529a26b1443c9332d4 ] Commit 6727ad9e206c ("nmi_backtrace: generate one-line reports for idle cpu= s") introduced a new text section called cpuidle; with that, we have a mechanism to add idling functions in such section and skip them from nmi_backtrace output, since they're useless and potentially flooding for such report. Happens that inlining might cause some real idle functions to end-up outside of such section; this is currently the case of ACPI processor_idle driver; the functions acpi_idle_enter_* do inline acpi_idle_do_entry(), hence they stay out of the cpuidle section. Fix that by marking such functions to also live in the cpuidle section. Fixes: 6727ad9e206c ("nmi_backtrace: generate one-line reports for idle cpu= s") Signed-off-by: Guilherme G.
