Name:ls - find last set bit in word*@x: the word to search* This is defined in a similar way as the libc and compiler builtin* ffs, but returns the position of the most significant set bit.* fls(value) returns 0 if value is 0 or the position of the last

Proto:static __always_inline int fls(unsigned int x)

Type:int

Parameter:

TypeParameterName
unsigned intx
338  asm("bsrl %1,%0":"=r"(r):"rm"(x), "0"(-1))
351  Return r + 1

div64_u64_remdiv64_u64_rem - unsigned 64bit divide with 64bit divisor and remainder*@dividend: 64bit dividend*@divisor: 64bit divisor*@remainder: 64bit remainder* This implementation is a comparable to algorithm used by div64_u64
div64_u64div64_u64 - unsigned 64bit divide with 64bit divisor*@dividend: 64bit dividend*@divisor: 64bit divisor* This implementation is a modified version of the algorithm proposed* by the book 'Hacker's Delight'. The original source and full proof

__ilog2_u32-constant log of base 2 calculators* - the arch may override these in asm/bitops.h if they can be implemented* more efficiently than using fls() and fls64()* - the arch is not required to handle n==0 if implementing the fallback
get_orderget_order - Determine the allocation order of a memory size*@size: The size for which to get the order* Determine the allocation order of a particular sized block of memory
