From: Harvey Harrison Date: Thu, 14 Feb 2008 23:23:53 +0000 (-0800) Subject: x86, kprobes: remove sparse warnings from x86 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f1452d424dc0e079fb97af8cb8d3a0f7b5fddd46;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git x86, kprobes: remove sparse warnings from x86 arch/x86/kernel/kprobes.c:584:16: warning: symbol 'kretprobe_trampoline_holder' was not declared. Should it be static? arch/x86/kernel/kprobes.c:676:6: warning: symbol 'trampoline_handler' was not declared. Should it be static? Make them static and add the __used attribute, approach taken from the arm kprobes implementation. kretprobe_trampoline_holder uses inline assemly to define the global symbol kretprobe_trampoline, but nothing ever calls the holder explicitly. trampoline handler is only called from inline assembly in the same file, mark it used and static.
