-size_t " len ,
-.BI "              int " prot ", int " flag );

-.\" asmlinkage int sys_free_hugepages(unsigned long addr);
-.fi
-.P
-.IR Note :
-glibc provides no wrappers for these system calls,
-necessitating the use of
-.BR syscall (2).
-.SH DESCRIPTION
-The system calls
-.BR alloc_hugepages ()
-and
-.BR free_hugepages ()
-were introduced in Linux 2.5.36 and removed again in Linux 2.5.54.
-They existed only on i386 and ia64 (when built with
-.BR CONFIG_HUGETLB_PAGE ).
-In Linux 2.4.20, the syscall numbers exist,
-but the calls fail with the error
-.BR ENOSYS .
-.P
-On i386 the memory management hardware knows about ordinary pages (4\ KiB)
-and huge pages (2 or 4\ MiB).
-Similarly ia64 knows about huge pages of
-several sizes.
-These system calls serve to map huge pages into the
-process's memory or to free them again.
-Huge pages are locked into memory, and are not swapped.
-.P
-The
-.I key
-argument is an identifier.
-When zero the pages are private, and
-not inherited by children.
-When positive the pages are shared with other applications using the same
-.IR key ,
-and inherited by child processes.
-.P
-The
-.I addr
-argument of
-.BR free_hugepages ()
-tells which page is being freed: it was the return value of a
-call to
-.BR alloc_hugepages ().
-(The memory is first actually freed when all users have released it.)
-The
-.I addr
-argument of
-.BR alloc_hugepages ()
-is a hint, that the kernel may or may not follow.
-Addresses must be properly aligned.
-.P
-The
-.I len
-argument is the length of the required segment.
-It must be a multiple of the huge page size.
-.P
-The
-.I prot
-argument specifies the memory protection of the segment.
-It is one of
-.BR PROT_READ ,
-.BR PROT_WRITE ,
-.BR PROT_EXEC .
-.P
-The
-.I flag
-argument is ignored, unless
-.I key
-is positive.
-In that case, if
-.I flag
-is
-.BR IPC_CREAT ,
-then a new huge page segment is created when none
-with the given key existed.
-If this flag is not set, then
-.B ENOENT
-is returned when no segment with the given key exists.
-.SH RETURN VALUE
-On success,
-.BR alloc_hugepages ()
-returns the allocated virtual address, and
-.BR free_hugepages ()
-returns zero.
-On error, \-1 is returned, and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-.TP
-.B ENOSYS
-The system call is not supported on this kernel.
-.SH FILES
-.TP
-.I /proc/sys/vm/nr_hugepages
-Number of configured hugetlb pages.
-This can be read and written.
-.TP
-.I /proc/meminfo
-Gives info on the number of configured hugetlb pages and on their size
-in the three variables HugePages_Total, HugePages_Free, Hugepagesize.
-.SH STANDARDS
-Linux on Intel processors.
-.SH HISTORY
-These system calls are gone;
-they existed only in Linux 2.5.36 through to Linux 2.5.54.
-.SH NOTES
-Now the hugetlbfs filesystem can be used instead.
-Memory backed by huge pages (if the CPU supports them) is obtained by
-using
-.BR mmap (2)
-to map files in this virtual filesystem.
-.P
-The maximal number of huge pages can be specified using the
-.B hugepages=
-boot parameter.
