mksysmap: Fix the mismatch of '.L' symbols in System.map
[ Upstream commit72d24accf0
] When System.map was generated, the kernel used mksysmap to filter the kernel symbols, but all the symbols with the second letter 'L' in the kernel were filtered out, not just the symbols starting with 'dot + L'. For example: ashimida@ubuntu:~/linux$ cat System.map |grep ' .L' ashimida@ubuntu:~/linux$ nm -n vmlinux |grep ' .L' ffff0000088028e0 t bLength_show ...... ffff0000092e0408 b PLLP_OUTC_lock ffff0000092e0410 b PLLP_OUTA_lock The original intent should be to filter out all local symbols starting with '.L', so the dot should be escaped.
