Jan,
"x86: Unify rwsem assembly implementation" broke the UML build on i386.
Please compile test you changes or CC me when you are touch something in arch/um/.
make ARCH=um SUBARCH=i386
and
make ARCH=um SUBARCH=x86_64
does not hurt. :-)
Thanks,
//richard

Subject: [PATCH] um: Make rwsem.S depend on CONFIG_RWSEM_XCHGADD_ALGORITHM
rwsem.S can only be used with CONFIG_RWSEM_XCHGADD_ALGORITHM.
This unbreaks the UML build on i386.
