-	ii) By default ELF headers are stored in ELF32 format (for i386). This

+	ii) By default ELF headers are stored in ELF64 format. Option
+	    --elf32-core-headers forces generation of ELF32 headers. gdb can

+	    headers can come handy for users who have got non-PAE systems and

        iii) Specify "irqpoll" as command line parameter. This reduces driver
             initialization failures in second kernel due to shared interrupts.
