    platform.  This document provides information specific to IA-64
    ONLY, to get additional information about the Linux kernel also
    read the original Linux README provided with the kernel.
- 
+
 INSTALLING the kernel:
 
  - IA-64 kernel installation is the same as the other platforms, see
    original README for details.
-   
- 
+
+
 SOFTWARE REQUIREMENTS
 
    Compiling and running this kernel requires an IA-64 compliant GCC
    compiler.  And various software packages also compiled with an
    IA-64 compliant GCC compiler.
- 
+
 
 CONFIGURING the kernel:
 
    Configuration is the same, see original README for details.
-  
-   
+
+
 COMPILING the kernel:
 
  - Compiling this kernel doesn't differ from other platform so read
    the original README for details BUT make sure you have an IA-64
    compliant GCC compiler.
- 
+
 IA-64 SPECIFICS
 
  - General issues:
- 
+
     o Hardly any performance tuning has been done. Obvious targets
       include the library routines (IP checksum, etc.). Less
       obvious targets include making sure we don't flush the TLB
       needlessly, etc.
-	  
+
     o SMP locks cleanup/optimization
-	
+
     o IA32 support.  Currently experimental.  It mostly works.
