[PATCH] x86: documentation fix regarding boot protocol

[Philipp Kohlbecher]

Documentation/x86/boot.txt describes payload_offset as the offset
from the end of the real-mode code. In fact, it is more accurately
described as the offset from the beginning of the protected-mode
code, as (a) this is how it is actually calculated and (b) the padding
after the real-mode code is not included in the offset.

-  If non-zero then this field contains the offset from the end of the
-  real-mode code to the payload.
+  If non-zero then this field contains the offset from the beginning
+  of the protected-mode code to the payload.

   The payload may be compressed. The format of both the compressed and
   uncompressed data should be determined using the standard magic
