An X.509 wrapper for a RSASSA-PSS signature contains additional

lost in the process.
Move the tcf0 check to enter_from_user_mode() and clear tcf0 in
exit_to_user_mode() to address the problem.
Note: Moving the check

The Devicetree standard specifies an 8 byte alignment of the FDT.
Code in libfdt expects this alignment for an FDT image in memory.
kmemdup() returns 4 byte alignment on openrisc. Replace kmemdup()
with kmalloc(), align pointer, memcpy() to get proper alignment.

But the ufs host sends SSU (START_STOP_UNIT) to wlun

suspended state. If so, it waits f
Resumes the actual scsi device the unit descriptor of which
is being accessed instead of the hba alone.
