2006-03-22	[PATCH] remove set_page_count() outside mm/	Nick Piggin	1	-1/+12
	set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count.

2006-03-22	[PATCH] mm: nommu use compound pages	Nick Piggin	1	-12/+0
	Now that compound page handling is properly fixed in the VM, move nommu over to using compound pages rather than rolling their own refcounting. nommu vm page refcounting is broken anyway, but there is no need to have divergent code in the core VM now, nor when it gets fixed.

2006-03-22	[PATCH] mm: make __put_page internal	Nick Piggin	1	-0/+11
	Remove __put_page from outside the core mm/. It is dangerous because it does not handle compound pages nicely, and misses 1->0 transitions. If a user later appears that really needs the extra speed we can reevaluate.

2006-01-06	[PATCH] FRV: Clean up bootmem allocator's page freeing algorithm	David Howells	1	-0/+2
	The attached patch cleans up the way the bootmem allocator frees pages. A new function, __free_pages_bootmem(), is provided in mm/page_alloc.c that is called from mm/bootmem.c to turn pages over to the main allocator. All the bits of code to initialise pages (clearing PG_reserved and setting the page count) are moved to here. The checks on page validity are removed, on the assumption that the struct page arrays will have been prepared correctly.

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+13
	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!
