[ Upstream commit 9ac50f7311dc8b39e355582f14c1e82da47a8196 ]
Thanks to CONFIG_DEBUG_SECTION_MISMATCH, empty functions can be
generated out of line. These can be called from noinstr code, so make
sure they're always inlined.
Fixes the following warnings:
vmlinux.o: warning: objtool: irqentry_nmi_enter+0xa2: call to ct_nmi_enter() leaves .noinstr.text section
vmlinux.o: warning: objtool: irqentry_nmi_exit+0x16: call to ct_nmi_exit() leaves .noinstr.text section
vmlinux.o: warning: objtool: irqentry_exit+0x78: call to ct_irq_exit() leaves .noinstr.text section
Fixes: 6f0e6c1598b1 ("context_tracking: Take IRQ eqs entrypoints over RCU")
