Subject: x86, extable: Remove open-coded exception table entries in arch/x86/kernel/test_rodata.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5d6f8d77ede50417dcca4c31a74f0d40a1ee537a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86, extable: Remove open-coded exception table entries in arch/x86/kernel/test_rodata.c

Remove open-coded exception table entries in arch/x86/kernel/test_rodata.c,
and replace them with _ASM_EXTABLE() macros; this will allow us to
change the format and type of the exception table entries.
