Subject[PATCH 0/3] Type aware module allocator
Date
This set implements the second part of module type aware allocator
(module_alloc_type), which was discussed in [1]. This part contains the
interface of the new allocator, as well as changes in x86 code to use the
new allocator (modules, BPF, ftrace, kprobe).

The set does not contain a binpack allocator to enable sharing huge pages
among different allocations. But this set defines the interface used by
the binpack allocator. [2] has some discussion on different options of the
binpack allocator.

Song Liu (3):
module: Introduce module_alloc_type
ftrace: Add swap_func to ftrace_process_locs()
x86/module: Use module_alloc_type
