1. ./genfilelist.pl arch/arc/include/asm/
2. Create arch/arc/include/uapi/asm/Kbuild as follows
+# UAPI Header export list
+include include/uapi/asm-generic/Kbuild.asm
3. ./disintegrate-one.pl arch/arc/include/{,uapi/}asm/<above-list>
4. Edit arch/arc/include/asm/Kbuild to remove ref to
asm-generic/Kbuild.asm
- To work around empty uapi/asm/setup.h added a placholder comment.
- Also a manual #ifdef __ASSEMBLY__ for a late ptrace change

/*

|
* This is much needed for ARC sigreturn optimization.
|
|
* This allows uClibc to piggback the addr of a sigreturn stub in sigaction,
|
|
* which allows sigreturn based re-entry into kernel after handling signal.
|
|
* W/o this kernel needs to "synthesize" the sigreturn trampoline on user
|
|
* mode stack which in turn forces the following:
|
|
* -TLB Flush (after making the stack page executable)
|
|
* -Cache line Flush (to make I/D Cache lines coherent)
