asm-generic: make more kernel-space headers mandatory
Change a header to mandatory-y if both of the following are met:
[1] At least one architecture (except um) specifies it as generic-y in
arch/*/include/asm/Kbuild
[2] Every architecture (except um) either has its own implementation
(arch/*/include/asm/*.h) or specifies it as generic-y in
arch/*/include/asm/Kbuild
This commit was generated by the following shell script.
----------------------------------->8-----------------------------------
arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d')
tmpfile=$(mktemp)
grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile
find arch -path 'arch/*/include/asm/Kbuild' |
xargs sed -n 's/^generic-y += \(.*\)/\1/p' | sort -u |
while read header
do
mandatory=yes
for arch in $arches
do
if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild &&
! [ -f arch/$arch/include/asm/$header ]; then
mandatory=no
break
fi
done
if [ "$mandatory" = yes ]; then
echo "mandatory-y += $header" >> $tmpfile
for arch in $arches
do
sed -i "/generic-y += $header/d" arch/$arch/include/asm/Kbuild
done
fi
done
sed -i '/^mandatory-y +=/d' include/asm-generic/Kbuild
LANG=C sort $tmpfile >> include/asm-generic/Kbuild

It is tedious to list generic-y for each arch that needs it.
So, mandatory-y works like a fallback default (by just wrapping
asm-generic one) when arch does not have a specific header
implementation.
See the following commits:

a1b39bae16a62ce4aae02d958224f19316d98b24
It is tedious to convert headers one by one, so I processed by a shell
script.
