Russell King	1b3cb73f73	[ARM] Tighten pfn_valid() test. Thomas Gleixner reported that mmaping and unmapping each physical page in turn eventually caused the kernel to oops. It appears that pfn_valid() in the discontigmem case was too simplistic for proper operation. Tighten the logic so we also check if the PFN is within the range of the selected memory node.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 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!	20 years ago

[ARM] Tighten pfn_valid() test.

Thomas Gleixner reported that mmaping and unmapping each physical
page in turn eventually caused the kernel to oops.  It appears
that pfn_valid() in the discontigmem case was too simplistic for
proper operation.

Tighten the logic so we also check if the PFN is within the range
of the selected memory node.

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!
