make: *** [.tmp_vmlinux1] Error 1
A function with a name like that doesn't _deserve_ to compile.
Would vector_reciprocal_square_root_estimate_floating_point() be any
better...
Anyway, this is just a machine insn mnemonic, so the function name is
fine
I believe.
#define push_end(res, size) do { unsigned long __sz = (size) ; \
- res->end = ((res->end + __sz) / (__sz + 1)) * (__sz + 1) + __sz; \
+ resource_size_t farEnd = (res->end + __sz); \
+ do_div(farEnd, (__sz + 1)); \
+ res->end = farEnd * (__sz + 1) + __sz; \
} while (0)
Size here is a) a misnomer (size + 1 is the actual size) and b) always
a power
of two minus one. So instead, do
#define push_end(res, mask) res->end = -(-res->end & ~(unsigned
long)mask)
(with a do { } while(0) armour if you prefer).
