Revision 1c48a177351ba8cbf6871f035496fce0e11d8fa3 authored by James Hogan on 20 May 2016, 22:28:38 UTC, committed by Ralf Baechle on 28 May 2016, 10:35:10 UTC
Toolchains may be used which support microMIPS but not VZ instructions
(i.e. binutis 2.22 & 2.23), so extend the explicitly encoded versions of
the guest COP0 register & guest TLB access macros to support microMIPS
encodings too, using the new macros.

This prevents non-microMIPS instructions being executed in microMIPS
mode during CPU probe on cores supporting VZ (e.g. M5150), which cause
reserved instruction exceptions early during boot.

config JFS_FS
	tristate "JFS filesystem support"
	select NLS
	select CRC32
	help
	  This is a port of IBM's Journaled Filesystem .  More information is
	  available in the file <file:Documentation/filesystems/jfs.txt>.

	  If you do not intend to use the JFS filesystem, say N.

config JFS_POSIX_ACL
	bool "JFS POSIX Access Control Lists"
	depends on JFS_FS
	select FS_POSIX_ACL
	help
	  Posix Access Control Lists (ACLs) support permissions for users and
	  groups beyond the owner/group/world scheme.

	  To learn more about Access Control Lists, visit the Posix ACLs for
	  Linux website <http://acl.bestbits.at/>.

	  If you don't know what Access Control Lists are, say N

config JFS_SECURITY
	bool "JFS Security Labels"
	depends on JFS_FS
	help
	  Security labels support alternative access control models
	  implemented by security modules like SELinux.  This option
	  enables an extended attribute handler for file security
	  labels in the jfs filesystem.

	  If you are not using a security module that requires using
	  extended attributes for file security labels, say N.

config JFS_DEBUG
	bool "JFS debugging"
	depends on JFS_FS
	help
	  If you are experiencing any problems with the JFS filesystem, say
	  Y here.  This will result in additional debugging messages to be
	  written to the system log.  Under normal circumstances, this
	  results in very little overhead.

config JFS_STATISTICS
	bool "JFS statistics"
	depends on JFS_FS
	help
	  Enabling this option will cause statistics from the JFS file system
	  to be made available to the user in the /proc/fs/jfs/ directory.
