Subject: [Patch 0/7] Implement crashkernel=auto
Date: Wed, 5 Aug 2009 07:19:02 -0400	[thread overview]
Message-ID: <20090805112123.6552.73574.sendpatchset@localhost.localdomain> (raw)


This series of patch implements automatically reserved memory for crashkernel,
by introducing a new boot option "crashkernel=auto". This idea is from Neil.

In case of breaking user-space applications, it modifies this boot option after
it decides how much memory should be reserved.

On different arch, the threshold and reserved memory size is different. Please
refer patch 7/7 which contains an update for the documentation.

Note: This patchset was only tested on x86_64 with differernt memory sizes.
