Peter Maydell	aafd758410	util: Clean up includes Clean up includes so that osdep.h is included first and headers which it implies are not included manually.

Peter Lieven	49f676a00a	bitops: unroll while loop in find_next_bit() this patch adopts the loop unrolling idea of bitmap_is_zero() to speed up the skipping of large areas with zeros in find_next_bit(). this routine is extensively used to find dirty pages in live migration. testing only the find_next_bit performance on a zeroed bitfield the loop onrolling decreased executing time by approx. 50% on x86_64.

Richard Henderson	265ce4a5ca	bitops: Use non-bitops ctzl The use of ctz has already eliminated zero, and thus the difference in edge conditions between the two routines is irrelevant.

Paolo Bonzini	fbeadf50f2	bitops: unify bitops_ffsl with the one in host-utils.h, call it bitops_ctzl We had two copies of a ffs function for longs with subtly different semantics and, for the one in bitops.h, a confusing name: the result was off-by-one compared to the library function ffsl. Unify the functions into one, and solve the name problem by calling the 0-based functions "bitops_ctzl" and "bitops_ctol" respectively. This also fixes the build on platforms with ffsl, including Mac OS X and Windows.

Corentin Chary	e0e53b2f1b	bitmap: add a generic bitmap and bitops library Add most used bitmap and bitops functions into bitmap.c and bitops.c. Theses functions are mostly copied from Linux kernel source. Some of these functions are already redefined in the VNC server. Some of them could be used for some block stuff. The yet yo be submitted NUMA work also need bitmaps. bitops_ffsl() and bitops_flsl() are here because bitops/bitmap works on unsigned long, not int, and we can't use current code because: * ffs only works on int * qemu_fls only works on int * ffsl is a GNU extension Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>	15 years ago
