Biederman" , Amerigo Wang , akpm@linux-foundation.org, Ingo Molnar , Anton Vorontsov 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. Signed-off-by: WANG Cong Cc: Neil Horman Cc: Ingo Molnar Cc: Eric W. Biederman Cc: Tony Luck Cc: Anton Vorontsov
