Commit 0e0345b77a ("kbuild: redo fake deps at include/config/*.h")
simplified the Kconfig/fixdep interaction a lot.
For CONFIG_FOO_BAR_BAZ, Kconfig now touches include/config/FOO_BAR_BAZ
instead of the previous include/config/foo/bar/baz.h .
This commit simplifies the TRIM_UNUSED_KSYMS feature in a similar way:
- delete .h suffix
- delete tolower()
- put everything in 1 directory
For EXPORT_SYMBOL(FOO_BAR_BAZ), scripts/adjust_autoksyms.sh now touches
include/ksym/FOO_BAR_BAZ instead of include/ksym/foo/bar/baz.h .
This is more precise, avoiding possibly unnecessary rebuilds.
EXPORT_SYMBOL(FOO_BAR_BAZ)
EXPORT_SYMBOL(_FOO_BAR_BAZ)
EXPORT_SYMBOL(__FOO_BAR_BAZ)
were previously mapped to the same header, include/ksym/foo/bar/baz.h
but now are handled separately.
