[PATCH 0/9] mm: generic adaptive large memory allocation APIs

[Changli Gao <xiaosuo@gmail.com>]

generic adaptive large memory allocation APIs

kv*alloc are used to allocate large contiguous memory and the users don't mind
whether the memory is physically or virtually contiguous. The allocator always
try its best to allocate physically contiguous memory first.

In this patch set, some APIs are introduced: kvmalloc(), kvzalloc(), kvcalloc(),
kvrealloc(), kvfree() and kvfree_inatomic().

Some code are converted to use the new generic APIs instead.
