* add-vmcore: add a prefix "VMCOREINFO_" to the vmcoreinfo macrosKen'ichi Ohmichi2007-10-17
| | | | | | | | | | | | Add a prefix "VMCOREINFO_" to the vmcoreinfo macros. Old vmcoreinfo macros were defined as generic names SYMBOL/SIZE/OFFSET /LENGTH/CONFIG, and it is impossible to grep for them. So these names should be changed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch set frees the restriction that makedumpfile users should install a vmlinux file (including the debugging information) into each system. makedumpfile command is the dump filtering feature for kdump. It creates a small dumpfile by filtering unnecessary pages for the analysis. To distinguish unnecessary pages, it needs a vmlinux file including the debugging information. These days, the debugging package becomes a huge file, and it is hard to install it into each system. To solve the problem, kdump developers discussed it at lkml and kexec-ml. As the result, we reached the conclusion that necessary information for dump filtering (called "vmcoreinfo") should be embedded into the first kernel file and it should be accessed through /proc/vmcore during the second kernel. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.0/1806.html) Dan Aloni created the patch set for the above implementation. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.1/1053.html) And I updated it for multi architectures and memory models.

* Delete filenames in comments.Dave Jones2007-10-13
| | | | | | | | | | | | | | | Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.
