| Subject: mksysmap: Fix the mismatch of '.L' symbols in System.map |
| |
| From: ashimida <ashimida@linux.alibaba.com> |
| |
| [ Upstream commit 72d24accf02add25e08733f0ecc93cf10fcbd88c ] |
| |
| 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. |
