+@@ -290,3 +290,38 @@ Due to the way that the exception table is built and 
needs to be ordered,
+ only use exceptions for code in the .text section.  Any other section
+ will cause the exception table to not be sorted correctly, and the
+ exceptions will fail.
++
++Things changed when 64-bit support was added to x86 Linux. Rather than
++double the size of the exception table by expanding the two entries
++from 32-bits to 64 bits, a clever trick was used to store addresses
++as relative offsets from the table itself. The assembly code changed
++from:
++      .long 1b,3b
++to:
++        .long (from) - .
++        .long (to) - .
++
++and the C-code that uses these values converts back to absolute addresses
++like this:
++
++      ex_insn_addr(const struct exception_table_entry *x)
++      {
++              return (unsigned long)&x->insn + x->insn;
++      }
++
++In v4.6 the exception table entry was expanded with a new field "handler".
++This is also 32-bits wide and contains a third relative function
++pointer which points to one of:
++
++1) int ex_handler_default(const struct exception_table_entry *fixup)
++   This is legacy case that just jumps to the fixup code
++2) int ex_handler_fault(const struct exception_table_entry *fixup)
++   This case provides the fault number of the trap that occurred at
++   entry->insn. It is used to distinguish page faults from machine
++   check.
++3) int ex_handler_ext(const struct exception_table_entry *fixup)
++   This case is used for uaccess_err ... we need to set a flag
++   in the task structure. Before the handler functions existed this
++   case was handled by adding a large offset to the fixup to tag
++   it as special.
++More functions can easily be added.
