enforce that, all EX_DATA masks are made signed integers. This\nworks, but relies on the particular implementation of FIELD_GET(),\ni.e. masking then shifting, not vice versa; and the particular\nplacement of the fields in the register.\n\nSwitch to using the dedicated FIELD_GET_SIGNED(), and relax those\nlimitations.\n\nSigned-off-by: Yury Norov <ynorov@nvidia.com>\n---\n arch/x86/include/asm/extable_fixup_types.h | 13 ++++---------\n arch/x86/mm/extable.c | 2 +-\n 2 files changed, 5 insertions(+), 10 deletions(-)", "diff": "diff --git a/arch/x86/include/asm/extable_fixup_types.h b/arch/x86/include/asm/extable_fixup_types.h\nindex 906b0d5541e8..fd0cfb472103 100644\n--- a/arch/x86/include/asm/extable_fixup_types.h\n+++ b/arch/x86/include/asm/extable_fixup_types.h\n@@ -2,15 +2,10 @@\n #ifndef _ASM_X86_EXTABLE_FIXUP_TYPES_H\n #define _ASM_X86_EXTABLE_FIXUP_TYPES_H\n \n-/*\n- * Our IMM is signed, as such it must live at the top end of the word.
