Prev: High process latencies due to MPC5200 FEC hard- soft-irq processing
Next: emacs and "linux" coding style
From: Neil Horman on 13 Jul 2010 09:50 Hey all- About 2 years ago now, I sent this patch upstream to allow makedumpfile to properly filter cores on ppc64: http://www.mail-archive.com/kexec(a)lists.infradead.org/msg02426.html It got acks from the kexec folks so I pulled it into RHEL, but I never checked back here to make sure it ever made it in, which apparently it didn't. It still needs to be included, so I'm reposting it here, making sure to copy all the ppc folks this time. I've retested it on the latest linus kernel and it works fine, allowing makedumpfile to find all the symbols it needs to properly strip a vmcore on ppc64.
