Now that ion_vm_fault doesn't need a struct page with a nonzero
refcount, there is no need allocate heap memory for cached pages using
split_page. Remove the ion_heap_alloc_pages and ion_heap_free_pages
helpers in favor of direct calls to alloc_pages and __free_pages,

In testing ion system heap allocations, I ran across two issues:
1) Not k*z*allocing the sg table. This can cause trouble if
we end up trying call sg_alloc_table() with too many entries,
then sg_alloc_table() internally fails and tries to free what it
thinks is internal table structure, which caus

When the shrinkers are called with GFP_HIGH free low memory first,
it is more important to have free than high memory.

Convert the ion ioctls to use _IOW instead of _IOWR where
appropriate, and factor out the copy_from_user and copy_to_user
based on the _IOC_DIR bits. For the existing incorrect ioctls,
add a function to wrap _IOC_DIR to return the corrected value.

Add support for Ingenic JZ4740 USB Device Controller through a
specific musb glue layer.
The platform data already available in tree for that USB Device
Controller was previously used by an out-of-tree USB gadget driver
which was not relying on the musb driver and was written by Ingenic
and the Qi
JZ4740 USB Device Controller is not OTG compatible and does not have DEVCTL
register in silicon.
During ethernet-over-usb transactions, on reset, musb driver tries to
read from DEVCTL and consequently sets device as host (A-Device)
instead of peripheral (B-Device), which makes it a composite devic

Following the fix I submitted a few weeks ago, here is a set of
patches that add USB support for the Ingenic JZ4740 MIPS SoC.
The JZ4740 is found in the Ben NanoNote handheld computer which is
built by the Qi-Hardware community.
Even though Ben NanoNote is already supported in the kernel,

dma_addr_t is not a phys_addr_t and should _not_ be emitted
with %pa.
Until %pad is in -next, use %lx, (unsigned long long)dma_addr_t.

In case of error, the function regulator_get() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

Prepare the clock at probe time, as there is no other appropriate place

This patch fixes the build break introduced by 3e1e4a5f. The mentioned
commit id makes the changes in file "include/linux/mfd/samsung/core.h"
by changing the members of structure sec_pmic_dev.
The patch replaces "regmap" with "regmap_pmic" because structure
sec_pmic_dev no more contains any member
