When a header file is removed from generic-y (often accompanied by the
addition of an arch specific header), the generated wrapper file will
persist, and in some cases may still take precedence over the new arch
header.For example commit f1fe2d21f4e1 ("MIPS: Add definitions for extended
context") removed ucontext.h from generic-y in arch/mips/include/asm/,
and added an arch/mips/include/uapi/asm/ucontext.h. The continued use of
the wrapper when reusing a dirty build tree resulted in build failures
in arch/mips/kernel/signal.c:arch/mips/kernel/signal.c: In function ‘sc_to_extcontext’:
arch/mips/kernel/signal.c:142:12: error: ‘struct ucontext’ has no member named ‘uc_extcontext’
return &uc->uc_extcontext;
^
Fix by detecting and removing wrapper headers in generated header
directories that do not correspond to a filename in generic-y, genhdr-y,
or the newly introduced generated-y.Reported-by: Jacek Anaszewski

Several arch/*/include/uapi/asm/* header simply include the
corresponding file. This patch allows such files to be
specified in uapi/asm/Kbuild via "generic-y += ..." to be automatically
generated (similar to asm/Kbuild).Signed-off-by: Catalin Marinas

There is an increasing amount of header files
shared between individual architectures in asm-generic.
To avoid a lot of dummy wrapper files that just
include the corresponding file in asm-generic provide
some basic support in kbuild for this.With the following patch an architecture can maintain
a list of files in the file arch/$(ARCH)/include/asm/KbuildTo use a generic file just add:
generic-y +=
For each file listed kbuild will generate the necessary
wrapper in arch/$(ARCH)/include/generated/asm.When installing userspace headers a wrapper is likewise created.
The original inspiration for this came from the unicore32
patchset - although a different method is used.The patch includes several improvements from Arnd Bergmann.
Michael Marek contributed Makefile.asm-generic.Remis Baima did an intial implementation along to achive
the same - see https://patchwork.kernel.org/patch/13352/Signed-off-by: Sam Ravnborg
