From c19c03fc749147f565e807fa65f1729066800571 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 4 Jun 2007 15:15:35 +1000 Subject: [POWERPC] unmap_vm_area becomes unmap_kernel_range for the public This makes unmap_vm_area static and a wrapper around a new exported unmap_kernel_range that takes an explicit range instead of a vm_area struct. This makes it more versatile for code that wants to play with kernel page tables outside of the standard vmalloc area. (One example is some rework of the PowerPC PCI IO space mapping code that depends on that patch and removes some code duplication and horrible abuse of forged struct vm_struct).
