41 * hvReleaseData in C as in the #if 0 section here. However, gcc
42 * refuses to believe that (u32)&x is a constant expression, so will
43 * not allow the xMsNucDataOffset field to be properly initialized.
44 * So, we declare hvReleaseData in inline asm instead. We use inline
45 * asm, rather than a .S file, because the assembler won't generate
46 * the necessary relocation for the LparMap either, unless that symbol
47 * is declared in the same source file. Finally, we put the asm in a
48 * dummy, attribute-used function, instead of at file scope, because
49 * file scope asms don't allow contraints. We want to use the "i"
50 * constraints to put sizeof() and offsetof() expressions in there,
51 * because including asm/offsets.h in C code then stringifying causes
52 * all manner of warnings.
