Hi, In include/asm-i386/rwsem.h:__up_read(), the auto variable 'tmp' is asserted to be in edx. This patch adjusts the constraint to match the variable. It could be argued that tmp should be declared register instead. I didn't because the function is inlined. The compiler will know how much register pressure there is in each instance.
