Hi experts.
I think all the macros with CONFIG_ prefix are supposed to be
defined in Kconfig.
But I've been long wondering why there exists one exception:
CONFIG_SHELL.
Is there any historical, or special reason?
Is it good to rename it to KBUILD_SHELL or something else?
Best Regards
Masahiro

Kbuild supports saving output files in a separate directory.
But the build directory must be created beforehand. For example,

Passing -rR for make headers_install is redundant because
the top Makefile has already set -rR to MAKEFLAGS.

The arch header directories include/asm-* were moved long ago.
Now we should check the existence of arch/*/include/uapi/asm/Kbuild
to see if an architecture supports the headers installation.
(Actually, um is the only architecture that does not have it.)

The exported headers were moved to uapi directories.
We should check the existence of arch/*/include/uapi/asm/Kbuild.

The current rounding of size is wrong:
- If start is sufficiently near the next page boundary, size
is decremented by more than enough and the last page is lost.
- If size is sufficiently small, it is wrapped around and gets
a bogus value.

Any advice?
How to fix this issue?

This line converts PHYS_OFFSET into PHYS_PFN_OFFSET.
It is better to use PAGE_SHIFT rather than the magic number 12.

This comment does not correspond to the actual code.
When zImage is loaded at a lower *OR* higher address of
the destination of Image, it won't overwrite itself.

Hi.
Is there a chance to fix this by the Linux 3.18 release?
Thanks.

Hi, Mike Turquette
I posted this trivial fix about 10 months ago.
Is it applicable?

As ARM ARM says, the bit 19-16 of ID_MMFR1 is always 0b because
ARMv7 requires a hierarchical cache implementation.
The line mcrp15, 0, r10, c7, c14, 0 is not reachable.
Moreover, the v7_flush_dcache_all in arch/arm/mm/cache-v7.S does not
check the ID_MMFR1.
