Subject: x86, bts, mm: clean up buffer allocation
X-Git-Tag: v2.6.31-rc1~401^2~62^2

x86, bts, mm: clean up buffer allocation

The current mm interface is asymetric. One function allocates a locked
buffer, another function only refunds the memory.

Change this to have two functions for accounting and refunding locked
memory, respectively; and do the actual buffer allocation in ptrace.

[ Impact: refactor BTS buffer allocation code ]
