Description Luis Henriques 2019-09-02 14:31:20 UTC
Since last dist-upgrade, I see warnings when, e.g. building a kernel:

awk: arch/x86/tools/gen-insn-attr-x86.awk:259: warning: regexp escape sequence `\:' is not a known regexp operator
awk: arch/x86/tools/gen-insn-attr-x86.awk:349: (FILENAME=arch/x86/lib/x86-opcode-map.txt FNR=41) warning: regexp escape sequence `\&' is not a known regexp operator

Apparently, this started happening after gawk upgrade to 5.0.1-1.2.

this has been fixed in https://github.com/torvalds/linux/commit/700c1018b86d0d4b3f1f2d459708c0cdf42b521d

which is in kernel 5.5 or newer.
