scripts/gdb: fix debugging modules compiled with hot/cold partitioning

2019-12-05T14:26:37Z

[ Upstream commit 8731acc5068eb3f422a45c760d32198175c756f8 ] gcc's -freorder-blocks-and-partition option makes it group frequently and infrequently used code in .text.hot and .text.unlikely sections respectively. At least when building modules on s390, this option is used by default. gdb assumes that all code is located in .text section, and that .text section is located at module load address. With such modules this is no longer the case: there is code in .text.hot and .text.unlikely, and either of them might precede .text. Fix by explicitly telling gdb the addresses of code sections. It might be tempting to do this for all sections, not only the ones in the white list. Unfortunately, gdb appears to have an issue, when telling it about e.g. loadable .note.gnu.build-id section causes it to think that non-loadable .note.Linux section is loaded at address 0, which in turn causes NULL pointers to be resolved to bogus symbols. So keep using the white list approach for the time being.

scripts/gdb: fix lx-lsmod refcnt

2015-05-29T01:25:19Z

Commit 2f35c41f58a9 ("module: Replace module_ref with atomic_t refcnt") changes the way refcnt is handled but did not update the gdb script to use the new variable. Since refcnt is not per-cpu anymore, we can directly read its value.

scripts/gdb: add empty package initialization script

This got lost during the initial merge process: Python requires an __init__.py script, even if empty, in order to accept a directory as package. Add it, this time as a non-empty file. Signed-off-by: Jan Kiszka Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
