Ilya Leoshkevich ff3f7465ee scripts/gdb: fix debugging modules compiled with hot/cold partitioning ... [ Upstream commit 8731acc506 ] 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.
