Subject: i386: remove temporary DO_TRAP macros, expanding the last one used
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f8e0870f589cfa45575dc7333cdf1b8f769e7900;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

i386: remove temporary DO_TRAP macros, expanding the last one used

Only one use of the DO_TRAP macros remains. Expand that one and
remove the macros now.
