[PATCH] ARM: 2723/2: remove __udivdi3 and __umoddi3 from the kernel
Patch from Nicolas Pitre Those are big, slow and generally not recommended for kernel code. They are even not present on i386. So it should be concluded that one could as well get away with do_div() alone. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

34 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
35 multiplies two u32 integers MULTIPLER and MULTIPLICAND,
36 and generates a two-part u32 product in HIGH_PROD and
37 LOW_PROD.
38
39 2) __umulsidi3(a,b) multiplies two u32 integers A and B,
40 and returns a u64 product. This is just a variant of umul_ppmm.
41
42 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
43 denominator) divides a two-word unsigned integer, composed by the
44 integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
45 places the quotient in QUOTIENT and the remainder in REMAINDER.
46 HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
47 If, in addition, the most significant bit of DENOMINATOR must be 1,
48 then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
49
50 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
51 denominator). Like udiv_qrnnd but the numbers are signed. The
52 quotient is rounded towards 0.
53
54 5) count_leading_zeros(count, x) counts the number of zero-bits from
55 the msb to the first non-zero bit. This is the number of steps X
56 needs to be shifted left to set the msb. Undefined for X == 0.
57
58 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
59 high_addend_2, low_addend_2) adds two two-word unsigned integers,
60 composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
61 LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
62 LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
63 lost.
64
65 7) sub_ddmmss(high_difference, low_difference, high_minuend,
66 low_minuend, high_subtrahend, low_subtrahend) subtracts two
67 two-word unsigned integers, composed by HIGH_MINUEND_1 and
68 LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
69 respectively. The result is placed in HIGH_DIFFERENCE and
70 LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
71 and is lost.
72
73 If any of these macros are left undefined for a particular CPU,
74 C macros are used. */
