help
The kernel needs to change the hardware exception vectors.
In nommu mode, the hardware exception vectors are normally
placed at address 0x00000000. However, this region may be
occupied by read-only memory depending on H/W design.
If the region contains read-write memory, say 'n' here.
If your CPU provides a remap facility which allows the exception
vectors to be mapped to writable memory, say 'n' here.
Otherwise, say 'y' here. In this case, the kernel will require
external support to redirect the hardware exception vectors to
the writable versions located at DRAM_BASE.

fs/cifs/CHANGES

Version 1.42
------------
Fix slow oplock break when mounted to different servers at the same time and
the tids match and we try to find matching fid on wrong server.
Version 1.41
------------
Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
configure stronger authentication. Fix sfu symlinks so they can
be followed (not just recognized). Fix wraparound of bcc on
read responses when buffer size over 64K and also fix wrap of
max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
cifs_user_read and cifs_readpages (when EAGAIN on send of smb
on socket is returned over and over). Add POSIX (advisory) byte range
locking support (requires server with newest CIFS UNIX Extensions
to the protocol implemented). Slow down negprot slightly in port 139
RFC1001 case to give session_init time on buggy servers.
Version 1.40
------------
Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
