| * nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger2009-11-2311-5/+17
| | | | | | | | | | | | | | | | | | Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger2009-11-2320-1786/+19
| | | | | | | | | | | | | | | | | | | | Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * futimens: Ducument why we need manual hidden_protoBernhard Reutner-Fischer2009-11-231-1/+6
| | | | | | | | | | | | | | Also, remove unneeded __need_timespec (It cuts off a tiny bit of work for CPP but is of course not strictly needed). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* | ldso: initialize stack_chk_guard after TLS is initializedNatanael Copa2009-11-271-13/+13
| | | | | | | | | | | | | | | | stack_chk_guard is on thread local storage so we need to init TLS before we can init stack_chk_guard. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This optimization is based on prefetching and 64bit data transfer via FPU (only for the little endianess) Tests shows that: ---------------------------------------- Memory bandwidth | Gain | sh4-300 | sh4-200 ---------------------------------------- 512 bytes to 16KiB | ~20% | ~25% from 32KiB to 16MiB | ~190% | ~5% ---------------------------------------- Signed-off-by: Austin Foxley <austinf@cetoncorp.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
