s390/hypfs: add interface for diagnose 0x304
To provide access to the set-partition-resource-parameter interface to user space add a new attribute to hypfs/debugfs: * s390_hypsfs/diag_304 The data for the query-partition-resource-parameters command can be access by a read on the attribute. All other diagnose 0x304 requests need to be submitted via ioctl with CAP_SYS_ADMIN rights. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
