Subject: [PATCH] arch: unexport asm/shmparam.h for all architectures
Most architectures do not export shmparam.h to user-space.
$ find arch -name shmparam.h | sort
arch/alpha/include/asm/shmparam.h
arch/arc/include/asm/shmparam.h
arch/arm64/include/asm/shmparam.h
arch/arm/include/asm/shmparam.h
arch/csky/include/asm/shmparam.h
arch/ia64/include/asm/shmparam.h
arch/mips/include/asm/shmparam.h
arch/nds32/include/asm/shmparam.h
arch/nios2/include/asm/shmparam.h
arch/parisc/include/asm/shmparam.h
arch/powerpc/include/asm/shmparam.h
arch/s390/include/asm/shmparam.h
arch/sh/include/asm/shmparam.h
arch/sparc/include/asm/shmparam.h
arch/x86/include/asm/shmparam.h
arch/xtensa/include/asm/shmparam.h
Strangely, some users of the asm-generic wrapper export shmparam.h
$ git grep 'generic-y += shmparam.h'
arch/c6x/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/h8300/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/hexagon/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/m68k/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/microblaze/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/openrisc/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/riscv/include/asm/Kbuild:generic-y += shmparam.h
arch/unicore32/include/uapi/asm/Kbuild:generic-y += shmparam.h
The newly added riscv correctly creates the asm-generic wrapper
in the kernel space, but the others (c6x, h8300, hexagon, m68k,
microblaze, openrisc, unicore32) create the one in the uapi directory.
Digging into the git history, now I guess fcc8487d477a ("uapi:
export all headers under uapi directories") was the misconversion.
Prior to that commit, no architecture exported to shmparam.h
As its commit description said, that commit exported shmparam.h
for c6x, h8300, hexagon, m68k, openrisc, unicore32.
83f0124ad81e ("microblaze: remove asm-generic wrapper headers")
accidentally exported shmparam.h for microblaze.
This commit unexports shmparam.h for those architectures.
There is no more reason to export include/uapi/asm-generic/shmparam.h,
so it has been moved to include/asm-generic/shmparam.h
