  scripts: objdiff: fix stale comments about .tmp_objdiff (2022-06-04
01:30:10 +0900)

----------------------------------------------------------------
Kbuild updates for v5.19 (2nd)

 - Fix build regressions for parisc, csky, nios2, openrisc

 - Simplify module builds for CONFIG_LTO_CLANG and CONFIG_X86_KERNEL_IBT

 - Remove arch/parisc/nm, which was presumably a workaround for old tools

 - Check the odd combination of EXPORT_SYMBOL and 'static' precisely

 - Make external module builds robust against "too long argument error"

 - Fix modpost to detect EXPORT_SYMBOL marked as __init or__exit
   (This uncovered a couple of potential issues of exported symbols)

 - Support j, k keys for moving the cursor in nconfig
