From 10b63956fce7f369cc37fd4d994f09bd5203efe4 Mon Sep 17 00:00:00 2001

Subject: UAPI: Plumb the UAPI Kbuilds into the user header installation and
 checking

Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.

The changes made in this commit are:

 (1) Exported generated files (of which there are currently four) are moved to
     uapi/ directories under the appropriate generated/ directory, thus we
     get:

	include/generated/uapi/linux/version.h
	arch/x86/include/generated/uapi/asm/unistd_32.h
	arch/x86/include/generated/uapi/asm/unistd_64.h
	arch/x86/include/generated/uapi/asm/unistd_x32.h

     These paths were added to the build as -I flags in a previous patch.

 (2) scripts/Makefile.headersinst is now given the UAPI path to install from
     rather than the old path.

     It then determines the old path from that and includes that Kbuild also
     if it exists, thus permitting the headers to exist in either directory
     during the changeover.

     I also renamed the "install" variable to "installdir" as it refers to a
     directory not the install program.

 (3) scripts/headers_install.pl is altered to take a list of source file paths
     instead of just their names so that the makefile can tell it exactly
     where to find each file.

     For the moment, files can be obtained from one of four places for each
     output directory:

	.../include/uapi/foo/
	.../include/generated/uapi/foo/
	.../include/foo/
	.../include/generated/foo/

     The non-UAPI paths will be dropped later.

- * This is the new flexible, extensible style NFSv2/v3 file handle.
- * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
- *
- * The file handle starts with a sequence of four-byte words.
- * The first word contains a version number (1) and three descriptor bytes
- * that tell how the remaining 3 variable length fields should be handled.
- * These three bytes are auth_type, fsid_type and fileid_type.
- *
- * All four-byte values are in host-byte-order.
- *
- * The auth_type field specifies how the filehandle can be authenticated
- * This might allow a file to be confirmed to be in a writable part of a
- * filetree without checking the path from it up to the root.
- * Current values:
- *     0  - No authentication.  fb_auth is 0 bytes long
- * Possible future values:
- *     1  - 4 bytes taken from MD5 hash of the remainer of the file handle
- *          prefixed by a secret and with the important export flags.
- *
- * The fsid_type identifies how the filesystem (or export point) is
- *    encoded.
- *  Current values:
- *     0  - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
- *        NOTE: we cannot use the kdev_t device id value, because kdev_t.h
- *              says we mustn't.  We must break it up and reassemble.
- *     1  - 4 byte user specified identifier
- *     2  - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
- *     3  - 4 byte device id, encoded for user-space, 4 byte inode number
- *     4  - 4 byte inode number and 4 byte uuid
- *     5  - 8 byte uuid
- *     6  - 16 byte uuid
- *     7  - 8 byte inode number and 16 byte uuid
- *
- * The fileid_type identified how the file within the filesystem is encoded.
- * This is (will be) passed to, and set by, the underlying filesystem if it supports
- * filehandle operations.  The filesystem must not use the value '0' or '0xff' and may
- * only use the values 1 and 2 as defined below:
- *  Current values:
- *    0   - The root, or export point, of the filesystem.  fb_fileid is 0 bytes.
- *    1   - 32bit inode number, 32 bit generation number.
- *    2   - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.

+ * This is the new flexible, extensible style NFSv2/v3 file handle.
+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
+ *
+ * The file handle starts with a sequence of four-byte words.
+ * The first word contains a version number (1) and three descriptor bytes
+ * that tell how the remaining 3 variable length fields should be handled.
+ * These three bytes are auth_type, fsid_type and fileid_type.
+ *
+ * All four-byte values are in host-byte-order.
+ *
+ * The auth_type field specifies how the filehandle can be authenticated
+ * This might allow a file to be confirmed to be in a writable part of a
+ * filetree without checking the path from it up to the root.
+ * Current values:
+ *     0  - No authentication.  fb_auth is 0 bytes long
+ * Possible future values:
+ *     1  - 4 bytes taken from MD5 hash of the remainer of the file handle
+ *          prefixed by a secret and with the important export flags.
+ *
+ * The fsid_type identifies how the filesystem (or export point) is
+ *    encoded.
+ *  Current values:
+ *     0  - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
+ *        NOTE: we cannot use the kdev_t device id value, because kdev_t.h
+ *              says we mustn't.  We must break it up and reassemble.
+ *     1  - 4 byte user specified identifier
+ *     2  - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
+ *     3  - 4 byte device id, encoded for user-space, 4 byte inode number
+ *     4  - 4 byte inode number and 4 byte uuid
+ *     5  - 8 byte uuid
+ *     6  - 16 byte uuid
+ *     7  - 8 byte inode number and 16 byte uuid
+ *
+ * The fileid_type identified how the file within the filesystem is encoded.
+ * This is (will be) passed to, and set by, the underlying filesystem if it supports
+ * filehandle operations.  The filesystem must not use the value '0' or '0xff' and may
+ * only use the values 1 and 2 as defined below:
+ *  Current values:
+ *    0   - The root, or export point, of the filesystem.  fb_fileid is 0 bytes.
+ *    1   - 32bit inode number, 32 bit generation number.
+ *    2   - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.
