| * |
| * 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). |
