Subject[PATCH 00/27] kbuild: yet another series of cleanups (modpost and LTO)
This is the third batch of cleanups in this development cycle.

This weekend, I wrote up the code I have been planning.

After a bunch of modpost refactoring, I got rid of the ugly code
in Makefiles.

With this, Kbuild will get back much simpler and cleaner.

Masahiro Yamada (27):
modpost: use snprintf() instead of sprintf() for safety
modpost: do not write out any file when error occurred
modpost: remove stale comment about sym_add_exported()
modpost: add a separate error for exported symbols without definition
modpost: retrieve the module dependency and CRCs in check_exports()
modpost: use bool type where appropriate
modpost: import include/linux/list.h
modpost: traverse modules in order
modpost: add sym_add_unresolved() helper
modpost: traverse unresolved symbols in order
modpost: use doubly linked list for dump_lists
modpost: move struct namespace_list to modpost.c
modpost: traverse the namespace_list in order
modpost: dump Module.symvers in the same order of modules.order
modpost: move static EXPORT_SYMBOL check to check_exports()
modpost: make multiple export error
modpost: make sym_add_exported() always allocate a new symbol
modpost: make sym_add_exported() a void function
modpost: use hlist for hash table implementation
modpost: mitigate false-negatives for static EXPORT_SYMBOL checks
kbuild: record symbol versions in *.cmd files
kbuild: generate a list of objects in vmlinux
modpost: retrieve symbol versions by parsing *.cmd files
modpost: generate linker script to collect symbol versions
kbuild: embed symbol versions at final link of vmlinux or modules
kbuild: stop generating *.symversions
kbuild: do not create *.prelink.o for Clang LTO or IBT
