2021-02-23tracing: add support for objtool mcountSami Tolvanen3-0/+23
This change adds build support for using objtool to generate __mcount_loc sections. Signed-off-by: Sami Tolvanen <[email protected]>
2021-02-23objtool: Don't autodetect vmlinux.oSami Tolvanen2-6/+2
With LTO, we run objtool on vmlinux.o, but don't want noinstr validation. This change requires --vmlinux to be passed to objtool explicitly. Suggested-by: Peter Zijlstra <[email protected]> Signed-off-by: Sami Tolvanen <[email protected]> Reviewed-by: Kees Cook <[email protected]>
2021-02-23objtool: Fix __mcount_loc generation with Clang's assemblerSami Tolvanen1-2/+15
When objtool generates relocations for the __mcount_loc section, it tries to reference __fentry__ calls by their section symbol offset. However, this fails with Clang's integrated assembler as it may not generate section symbols for every section. This patch looks up a function symbol instead if the section symbol is missing, similarly to commit e81e07244325 ("objtool: Support Clang non-section symbols in ORC generation").

2021-02-23objtool: Add a pass for generating __mcount_locPeter Zijlstra6-2/+88
Add the --mcount option for generating __mcount_loc sections needed for dynamic ftrace. Using this pass requires the kernel to be compiled with -mfentry and CC_USING_NOP_MCOUNT to be defined in Makefile.

2021-02-23Kbuild: disable TRIM_UNUSED_KSYMS optionLinus Torvalds1-0/+1
The removal of EXPORT_UNUSED_SYMBOL() in commit 367948220fce looks like (and was sold as) a no-op, but it actually had a rather serious and subtle side effect: the UNUSED_SYMBOLS option not only enabled the removed (unused) functionality, it also _disabled_ the TRIM_UNUSED_KSYMS functionality. And it turns out that TRIM_UNUSED_KSYMS is a huge time waste, and takes up a third of the kernel build time for me. For no actual upside, since no distro is likely to ever be able to enable it (because they all support external kernel modules). Rather than re-enable EXPORT_UNUSED_SYMBOL, this just disables the TRIM_UNUSED_KSYMS option by marking it broken. I'm tempted to just remove the support entirely, but maybe somebody has a use-case and can fix the behavior of it. I could have just disabled it for COMPILE_TEST, but it really smells like the TRIM_UNUSED_KSYMS option is badly done and not really useful, so this takes the more direct approach - let's see if anybody ever actually notices or complains.

The number of functions supported by the endpoint controller is configured in LM_EP_FUNC_CFG based on func_no member of struct pci_epf. Now that an endpoint function can be associated with two endpoint controllers (primary and secondary), just using func_no will not suffice as that will take into account only if the endpoint controller is associated with the primary interface of endpoint function.
