kernel implementation.

linux, compat: add missing definitions for ubi

2015-10-26T08:22:02+00:00

add missing definitions for the ubi/ubifs sync
with linux 4.2, also change "#define kfree ..."
into a static inline, so prevent ubi compile error:

   CC      drivers/mtd/ubi/fastmap.o
drivers/mtd/ubi/fastmap.c: In function 'scan_pool':
drivers/mtd/ubi/fastmap.c:475:3: error: called object 'free' is not a function

linux_compat: handle __GFP_ZERO in kmalloc()

2015-07-22T13:30:44+00:00

Currently, kzalloc() returns zero-filled memory, while kmalloc()
simply ignores the second argument and never fills the memory
area with zeros.

I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does,
which will make it easier to add more memory allocator variants.

With the introduction of __GFP_ZERO flag, going forward, kzmalloc()
variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

linux_compat: move vzalloc() to header file as an inline function

2015-07-22T13:30:39+00:00

The vzalloc(size) is equivalent to kzalloc(size, 0).  Move it to
include/linux/compat.h as an inline function in order to avoid the
function call overhead.

linux_compat: remove cpu_relax() define

2015-07-22T13:30:37+00:00

The macro cpu_relax() is defined by several headers in different
ways.

arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows:
  #define cpu_relax()	barrier()

On the other hand, include/linux/compat.h defines it as follows:
  #define cpu_relax() do {} while (0)

If both headers are included from the same source file, the warning
  warning: "cpu_relax" redefined [enabled by default]
is displayed.

It effectively makes it impossible to include 
from some sources.  Drop the latter.

usb: dwc3: gadget: make dwc3 gadget build in uboot

2015-04-14T03:48:09+00:00

Did a bunch of things to get dwc3/gadget.c compile in u-boot without
build errors and warnings
*) Changed the included header files to that used in u-boot.
*) Used dma_alloc_coherent and dma_free_coherent APIs of u-boot
*) removed sg support
*) remove jiffies and used a simple while loop
*) removed irq support and added a function to call these interrupt handler.

include: move various macros to include/linux/kernel.h

2014-11-20T16:28:25+00:00

U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.
