kexec: make extended crashkernel= syntax less confusing

2008-05-01T15:04:00+00:00

The extended crashkernel syntax is a little confusing in the way it handles
ranges.  eg:

 crashkernel=512M-2G:64M,2G-:128M

Means if the machine has between 512M and 2G of memory the crash region should
be 64M, and if the machine has 2G of memory the region should be 64M.  Only if
the machine has more than 2G memory will 128M be allocated.

Although that semantic is correct, it is somewhat baffling.  Instead I propose
that the end of the range means the first address past the end of the range,
ie: 512M up to but not including 2G.

kdump: documentation cleanups

2007-10-17T15:43:06+00:00

This cleans up kdump documentation a bit. Plus I do not think we want
to mention Linux trademark in _every_ file in documentation....

Add reset_devices to the recommended parameters

2007-10-17T15:43:06+00:00

This patch adds the "reset_devices" option (that's used only by one device
driver for now) to the recommended list of command line parameters for kdump.

Meaning (Documentation/kernel-parameters.txt):
    reset_devices   [KNL] Force drivers to reset the underlying device
                    during initialization.

Express relocatability of kernel on x86_64 in documentation

2007-10-17T15:43:05+00:00

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.

[PATCH] kexec: fix references to init in documentation for kexec

2007-02-12T17:48:29+00:00

I've noticed that the boot options are not correct for in the documentation
for kdump.  The "init" keyword is not necessary, and causes a kernel panic
when booting with an initrd on Fedora 5.
