* linux_compat: handle __GFP_ZERO in kmalloc()Masahiro Yamada2015-07-22-8/+12
| | | | | | | | | | | | | | | | | 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 functionMasahiro Yamada2015-07-22-2/+4
| | | | | | | | | | 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() defineMasahiro Yamada2015-07-22-2/+0
| | | | | | | | | | | | | | | | | | | | | | | 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 <linux/compat.h> from some sources. Drop the latter.

* include: move various macros to include/linux/kernel.hMasahiro Yamada2014-11-20-54/+0
| | | | | | | | | | | | | | | | | | | | | | | 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.

* linux/compat.h: port lower_32_bits and upper_32_bits from LinuxLijun Pan2014-07-22-0/+19
| | | | | | | | | | | | | | [backport from linux commit 204b885e and 218e180e7] 64 bit processors are becomming more and more popular. lower_32_bits and upper_32_bits save our labor doing shifts/manipulations like (u32)(n) and (u32)((n) >> 32). They are good helpers in both little and big endian cases. Port these two functions here from Linux:include/linux/kernel.h, cater the comment message to little/big endian cases. Later on, developers could include linux/compat.h if they want to use these two functions. Signed-off-by: Lijun Pan <Lijun.Pan@freescale.com>
* linux/compat.h: move dev_err, dev_info and dev_dbg from usb driver to compat.hWu, Josh2013-08-22-0/+8
| | | | | | | | | | | | Since kernel code current use many dev_xxx() instead of using printk. To compatible, move those dev_xxx from usb driver to linux/compat.h. Then all driver code can use dev_err, dev_info and dev_vdbg. This patch also removed duplicated macro definitions in usb driver.
