|
* First, use the Linux header files and the C standard library replacmenent versions

|
* the OS port files. The second approach is to use our own defines/prototypes and
|
* functions we have provided in the Linux OSL, i.e. linux_osl.c. Use this approach when
|
* compiling the files that make up the hybrid binary. We are ensuring we
|
* don't directly link to the kernel replacement routines from the hybrid binary.
|
*
|
* NOTE: The issue we are trying to avoid is any questioning of whether the
|
* hybrid binary is derived from Linux. The wireless common code (wlc) is designed
|
* to be OS independent through the use of the OSL API and thus the hybrid binary doesn't
|
* derive from the Linux kernel at all. But since we defined our OSL API to include
|
* a small collection of standard C library routines and these routines are provided in
|
* the kernel we want to avoid even the appearance of deriving at all even though clearly
|
* usage of a C standard library API doesn't represent a derivation from Linux. Lastly
|
* note at the time of this checkin 4 references to memcpy/memset could not be eliminated
|
* from the binary because they are created internally by GCC as part of things like
|
* structure assignment. I don't think the compiler should be doing this but there is
|
* no options to disable it on Intel architectures (there is for MIPS so somebody must
|
* agree with me). I may be able to even remove these references eventually with
|
* a GNU binutil such as objcopy via a symbol rename (i.e. memcpy to osl_memcpy).
