32 The kernel needs to change the hardware exception vectors.
33 In nommu mode, the hardware exception vectors are normally
34 placed at address 0x00000000. However, this region may be
35 occupied by read-only memory depending on H/W design.
36
37 If the region contains read-write memory, say 'n' here.
38
39 If your CPU provides a remap facility which allows the exception
40 vectors to be mapped to writable memory, say 'n' here.
41
42 Otherwise, say 'y' here. In this case, the kernel will require
43 external support to redirect the hardware exception vectors to
44 the writable versions located at DRAM_BASE.

1Version 1.42
2------------
3Fix slow oplock break when mounted to different servers at the same time and
4the tids match and we try to find matching fid on wrong server.
5
6Version 1.41
7------------
8Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
9configure stronger authentication. Fix sfu symlinks so they can
10be followed (not just recognized). Fix wraparound of bcc on
11read responses when buffer size over 64K and also fix wrap of
12max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
13cifs_user_read and cifs_readpages (when EAGAIN on send of smb
14on socket is returned over and over). Add POSIX (advisory) byte range
15locking support (requires server with newest CIFS UNIX Extensions
16to the protocol implemented). Slow down negprot slightly in port 139
17RFC1001 case to give session_init time on buggy servers.
