Express relocatability of kernel on x86_64 in documentation

Browse Source 
This patch adapts the Documentation/kdump/kdump.txt file to express the fact
that the x86_64 kernel is now also relocatable.  This makes i386 and x86_64
now behave the same, simplifying the documentation.

1) On x86 and x86_64, disable symmetric multi-processing support

CONFIG_SMP=n
(If CONFIG_SMP=y, then specify maxcpus=1 on the kernel command line
when loading the dump-capture kernel, see section "Load the Dump-capture
Kernel".)
2) Use a suitable value for "Physical address where the kernel is
loaded" (under "Processor type and features"). This only appears when
"kernel crash dumps" is enabled. By default this value is 0x1000000
(16MB). It should be the same as X in the "crashkernel=Y@X" boot
parameter.
For x86_64, normally "CONFIG_PHYSICAL_START=0x1000000".

For i386 and x86_64:
- Use vmlinux if kernel is not relocatable.
