There are plenty of header includes like:
#include <asm/kmap_size.h>
Yes and in reality that includes those,
./arch/arm64/include/generated/asm/kmap_size.h
./arch/riscv/include/generated/asm/kmap_size.h
./arch/arc/include/generated/asm/kmap_size.h
./arch/x86/include/generated/asm/kmap_size.h
./arch/powerpc/include/generated/asm/kmap_size.h
./arch/arm/include/generated/asm/kmap_size.h
Which contain:
$ cat arch/powerpc/include/generated/asm/kmap_size.h
#include <asm-generic/kmap_size.h>
So what is the problem really ?
Thanks for the explanation. I was trying to reuse some driver source
code in another project such that it compiles the related files in Linux
and ran into a compilation issue, and the error was that the header file
asm-generic/kmap_size.h was not found.
I just realized that once the kernel is built, the path asm/kmap_size.h
will exist, and hence there is no need for this patch.
