2005-10-29[PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addressesRoland Dreier
Change the phys_mem_access_prot() function to take a pfn instead of an address. This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages.

2005-10-28[PATCH] Driver Core: fix up all callers of class_device_create()Greg Kroah-Hartman
The previous patch adding the ability to nest struct class_device changed the paramaters to the call class_device_create(). This patch fixes up all in-kernel users of the function. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-08-13Fix up mmap of /dev/kmemLinus Torvalds
This leaves the issue of whether we should deprecate the whole thing (or if we should check the whole mmap range, for that matter) open. Just do the minimal fix for now.
2005-06-25[PATCH] kexec code cleanupManeesh Soni
o Following patch provides purely cosmetic changes and corrects CodingStyle guide lines related certain issues like below in kexec related files o braces for one line "if" statements, "for" loops, o more than 80 column wide lines, o No space after "while", "for" and "switch" key words o Changes: o take-2: Removed the extra tab before "case" key words. o take-3: Put operator at the end of line and space before "*/" Signed-off-by: Maneesh Soni <maneesh@in.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-25[PATCH] kdump: cleanups for dump file access in linear raw formatVivek Goyal
Removed the dependency on backup region. Now all the information is encoded in ELF format. /dev/oldmem is a dummy interface. User space tool need to be intelligent enough to parse the elf headers and read the relevant memory areas with the help of /dev/oldmem.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
