Removes some functions that are not used anywhere:
parisc_personality() parisc_fallocate() parisc_sync_file_range()
parisc_fadvise64_64() parisc_readahead() parisc_pwrite64() parisc_pread64()
parisc_ftruncate64() parisc_truncate64()
This was partially found by using a static code analysis program called
cppcheck.
NAK.
Those functions implement syscalls specific to the parisc ABI.
They are referenced in the syscall table which gets generated by the
ENTRY_OURS()
macro in arch/parisc/kernel/syscall_table.S
