Remove many duplicated words under Documentation/ and do other small
cleanups.Examples:
"and and" --> "and"
"in in" --> "in"
"the the" --> "the"
"the the" --> "to the"

In a testament to the utter simplicity and logic of the English

10-15 incorrect ones.Signed-Off-By: Lee Revell

o Specify "irqpoll" command line option which loading second kernel. This
helps in reducing driver initialization failures in second kernel due
to shared interrupts.
o Enabled LAPIC/IOAPIC support for UP kernels in second kernel. This reduces
the chances of devices sharing the irq and hence reduces the chances of
driver initialization failures in second kernel.
o Build a UP capture kernel and disabled SMP support.Signed-off-by: Vivek Goyal

This patch contains the documentation for the kexec based crash dump tool.
Quick kdump-howto
================================================================1) Download and build kexec-tools.
2) Download and build the latest kexec/kdump (-mm) kernel patchset.
Two kernels need to be built in order to get this feature working.A) First kernel:
a) Enable "kexec system call" feature:
CONFIG_KEXEC=y
b) Physical load address (use default):
CONFIG_PHYSICAL_START=0x100000
c) Enable "sysfs file system support":
CONFIG_SYSFS=y
d) Boot into first kernel with the command line parameter "crashkernel=Y@X":
For example: "crashkernel=64M@16M".B) Second kernel:
a) Enable "kernel crash dumps" feature:
CONFIG_CRASH_DUMP=y
b) Physical load addreess, use same load address as X in "crashkernel"
kernel parameter in d) above, e.g., 16 MB or 0x1000000.
CONFIG_PHYSICAL_START=0x1000000
c) Enable "/proc/vmcore support" (Optional, in Pseudo filesystems).
CONFIG_PROC_VMCORE=y3) Boot into the first kernel.
4) Load the second kernel to be booted using:
kexec -p --crash-dump --args-linux --append="root=
maxcpus=1 init 1"5) System reboots into the second kernel when a panic occurs. A module can be
written to force the panic, for testing purposes.6) See Documentation/kdump.txt for how to read the first kernel's
memory image and how to analyze it.Signed-off-by: Hariprasad Nellitheertha
