Notes on loading the dump-capture kernel:
* By default, the ELF headers are stored in ELF64 format to support
- systems with more than 4GB memory. The --elf32-core-headers option can
- be used to force the generation of ELF32 headers. This is necessary
- because GDB currently cannot open vmcore files with ELF64 headers on
- 32-bit systems. ELF32 headers can be used on non-PAE systems (that is,
- less than 4GB of memory).
+ systems with more than 4GB memory. On i386, kexec automatically checks if
+ the physical RAM size exceeds the 4 GB limit and if not, uses ELF32.
+ So, on non-PAE systems, ELF32 is always used.

* The "irqpoll" boot parameter reduces driver initialization failures
due to shared interrupts in the dump-capture kernel.
