modpost: Add .irqentry.text to OTHER_SECTIONS

2024-12-14T18:59:56Z

commit 7912405643a14b527cd4a4f33c1d4392da900888 upstream. The compiler can fully inline the actual handler function of an interrupt entry into the .irqentry.text entry point. If such a function contains an access which has an exception table entry, modpost complains about a section mismatch: WARNING: vmlinux.o(__ex_table+0x447c): Section mismatch in reference ... The relocation at __ex_table+0x447c references section ".irqentry.text" which is not in the list of authorized sections. Add .irqentry.text to OTHER_SECTIONS to cure the issue.

init/modpost: conditionally check section mismatch to __meminit*

2024-12-09T09:32:59Z

[ Upstream commit 73db3abdca58c8a014ec4c88cf5ef925cbf63669 ] This reverts commit eb8f689046b8 ("Use separate sections for __dev/ _cpu/__mem code/data"). Check section mismatch to __meminit* only when CONFIG_MEMORY_HOTPLUG=n. With this change, the linker script and modpost become simpler, and we can get rid of the __ref annotations from the memory hotplug code.

modpost: disallow the combination of EXPORT_SYMBOL and __meminit*

[ Upstream commit a3df1526da480c089c20868b7f4d486b9f266001 ] Theoretically, we could export conditionally-discarded code sections, such as .meminit*, if all the users can become modular under a certain condition. However, that would be difficult to control and such a tricky case has never occurred.

modpost: disallow driver to reference .meminit sections

2024-12-09T09:32:58Z

[ Upstream commit 50cccec15c48814765895891ca0d95d989b6a419 ] Drivers must not reference .meminit* sections, which are discarded when CONFIG_MEMORY_HOTPLUG=n. The reason for whitelisting "*driver" in the section mismatch check was to allow drivers to reference symbols annotated as __devinit or __devexit that existed in the past. Those annotations were removed by the following commits: - 54b956b90360 ("Remove __dev* markings from init.h") - 92e9e6d1f984 ("modpost.c: Stop checking __dev* section mismatches") Remove the stale whitelist.
