      powerpc: add asm/stat.h to UAPI compile-test coverage · c01013a2
      Masahiro Yamada authored 
      asm/stat.h is currently excluded from the UAPI compile-test for
ARCH=powerpc because of the errors like follows:

    HDRTEST usr/include/asm/stat.h
  In file included from <command-line>:32:
  ./usr/include/asm/stat.h:32:2: error: unknown type name 'ino_t'
     32 |  ino_t  st_ino;
        |  ^~~~~
  ./usr/include/asm/stat.h:35:2: error: unknown type name 'mode_t'
     35 |  mode_t  st_mode;
        |  ^~~~~~
  ./usr/include/asm/stat.h:40:2: error: unknown type name 'uid_t'
     40 |  uid_t  st_uid;
        |  ^~~~~
  ./usr/include/asm/stat.h:41:2: error: unknown type name 'gid_t'
     41 |  gid_t  st_gid;
        |  ^~~~~

The errors can be fixed by prefixing the types with __kernel_.

Then, remove the no-header-test entry from user/include/Makefile.

      kbuild: prevent exported headers from including <stdlib.h>, <stdbool.h> · 02a6e4be
      Masahiro Yamada authored 
      Some UAPI headers included <stdlib.h>, like this:

  #ifndef __KERNEL__
  #include <stdlib.h>
  #endif

As it turned out, they just included it for no good reason.

After some fixes, now I can compile-test UAPI headers
(CONFIG_UAPI_HEADER_TEST=y) without including <stdlib.h> from the
system header search paths.

To avoid somebody getting it back again, this commit adds the dummy
header, usr/dummy-include/stdlib.h

I added $(srctree)/usr/dummy-include to the header search paths.
Because it is searched before the system directories, if someone
tries to include <stdlib.h>, they will see the error message.

While I am here, I also replaced $(objtree)/usr/include with $(obj),
but it has no functional change.

If we can make kernel headers self-contained (that is, none of exported
kernel headers includes system headers), we will be able to add the
-nostdinc flag, but that is much far from where we stand now.

As a realistic solution, we can ban header inclusion individually by
putting a dummy header into usr/dummy-include/.

Currently, no header include <stdbool.h>. I put it as well before somebody
attempts to use it.

      agpgart.h: do not include <stdlib.h> from exported header · 783eb354
      Masahiro Yamada authored 
      Commit 35d0f1d5 ("include/uapi/linux/agpgart.h: include stdlib.h in
userspace") included <stdlib.h> to fix the unknown size_t error, but
I do not think it is the right fix.

This header already uses __kernel_size_t a few lines below.

Replace the remaining size_t, and stop including <stdlib.h>.
