Subject: [PATCH] s390/zcrypt: remove set_fs() invocation in zcrypt device
driver
This patch reworks the zcrypt device driver so that the set_fs()
invocation is not needed any more. Instead there is a new flag bool
usersp

Can you avoid the pointless long lines in the function
This patch reworks the zcrypt device driver so that the set_fs()
invocation is not needed any more. Instead there is a new flag bool
userspace passed through all the functions which tells if the pointer
arguments are userspace or kernelspace. Together with the two new
inline functions
