+  and some IBM RS/6000 systems), CHRP (Common Hardware Reference
+  Platform), and several embedded PowerPC systems containing 4xx, 6xx,
+  7xx, 8xx, 74xx, and 82xx processors.  Currently, the default option
+  is to build a kernel which works on the first three. 
+
+AltiVec Kernel Support
+CONFIG_ALTIVEC
+  This option enables kernel support for the Altivec extensions to the
+  PowerPC processor. The kernel currently supports saving and restoring
+  altivec registers, and turning on the 'altivec enable' bit so user
+  processes can execute altivec instructions.
+
+  This option is only usefully if you have a processor that supports 
+  altivec (G4, otherwise known as 74xx series), but does not have
+  any affect on a non-altivec cpu (it does, however add code to the
+  kernel).
+
+  If in doubt, say Y here.
+
+Thermal Management Support
+CONFIG_TAU
+  G3 and G4 processors have an on-chip temperature sensor called the
+  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
+  temperature within 2-4 degrees celcius. This option shows the current
+  on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+  Unfortunately, on some chip revisions, this sensor is very inaccurate
+  and in some cases, does not work at all, so don't assume the cpu
+  temp is actually what /proc/cpuinfo says it is.
+
+Interrupt driven TAU driver
+CONFIG_TAU_INT
+  The TAU supports an interrupt driven mode which causes an interrupt
+  whenever the temperature goes out of range. This is the fastest way
+  to get notified the temp has exceeded a range. With this option off,
+  a timer is used to re-check the temperature periodically.
+
+  However, on some cpus it appears that the TAU interrupt hardware
+  is buggy and can cause a situation which would lead unexplained hard
+  lockups.
+
+  Unless you are extending the TAU driver, or enjoy kernel/hardware
+  debugging, leave this option off.
+
+Average high and low temp
+CONFIG_TAU_AVERAGE
+  The TAU hardware can compare the temperature to an upper and lower bound.
+  The default behavior is to show both the upper and lower bound in 
+  /proc/cpuinfo. If the range is large, the temperature is either changing
+  a lot, or the TAU hardware is broken (likely on some G4's). If the range
+  is small (around 4 degrees), the temperature is relatively stable.
+
+Support for CUDA based PowerMacs

+  This provides support for CUDA based Power Macintosh systems.  This

 Known bugs and (mis-)features
 =============================
 
 - Do not use the driver for writing as it corrupts the file system. If you do
   use it, get the Linux-NTFS tools and use the ntfsfix utility after
   dismounting a partition you wrote to.
 
-- Use the show_sys_files mount option which should make things work generally
-  better. (It results in both the short and long file names being shown as well
-  as the sytem files.)
-
 - Writing of extension records is not supported properly.
 
+- $MFT extension is badly broken and really needs rewriting.

 ChangeLog
 =========
 
+NTFS 1.1.17:
+
+	- Fixed system file handling. No longer need to use show_sys_files
+	  option for driver to work fine. System files are now always treated
+	  the same, but without the option, they are made invisible to
+	  directory listings. As a result system files can once again be opened
+	  even without the show_sys_files option. This is important for the
+	  statfs system call to work properly, for example.
+	- Implemented MFT zone including mount parameter to tune it (just like
+	  in Windows via the registry, only we make it per mount rather than
+	  global for the whole driver, so we are better but we have no way of
+	  storing the value as we don't have a registry so either specify on
+	  each mount or put it in /etc/fstab). [Stage 1 of 3, mount parameter
+	  handling.]
+	- Fixed fixup functions to handle corruption cases and to return error
+	  codes to the caller.
+	- Made fixup functions apply hotfixes where sensible. [Stage 1 of 2+,
+	  in memory only.]
+	- Fixed ommission of "NTFS: " string in ntfs_error() output.
+	- Fixed stupid if statement bug in unistr.c. Thanks to Yann E. Morin
+	  for spotting it. 
+	- Get rid of all uses of max and min macros. This actually allowed for
+	  optimizing the code in several places so it was a Good Thing(TM).
+	- Make ntfs use generic_file_open to enforce the O_LARGEFILE flag.
+	- Detect encrypted files and refuse to access them (return EACCES
+	  error code to user space).
+	- Fix handling of encrypted & compressed files so that an encrypted
+	  file no longer is considered to be compressed (this was causing
+	  kernel segmentation faults).
+
 NTFS 1.1.16:
 
 	- Removed non-functional uni_xlate mount options.
