* MFC r261530ian2014-07-251-0/+9
| | | | | | Set the malloc alignment to 64 bytes on platforms that use the U-Boot API device drivers. Recent versions of u-boot run with the MMU enabled, and require DMA-based I/O to be aligned to cache line boundaries.
* - Removing some unneeded definitions of NULL(cruft related to 1970's C).avatar2011-07-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | In C90, NULL is guaranteed to be declared in <stddef.h> and also in <string.h>. Though the correct way to define NULL in FreeBSD is to include <sys/_null.h>, other parts of libstand still require <string.h> to build; therefore, we keep <string.h> in stand.h and add a note about this; - Removing no longer used 'Prototype' definition. Quote from bde@: 'Cruft related to getting incomplete struct declarations within prototypes forward-declared before the structs. It doesn't mean "prototype" but only part of a prototype-related hack. No longer used.' - Replacing iaddr_t with uintptr_t; - Removing use of long double to determine alignment. Use a fixed 16 byte alignment instead; Reviewed by: bde Obtained from: DragonFlyBSD (partially) MFC after: 1 month

compact and much better one donated by Matt Dillon. Implement a simple sbrk() which uses the existing setheap() api. Remove the custom allocator from the UFS code. It wasn't working quite right, and it shouldn't be needed with the new allocator. Fix a serious problem with changing the value of already-existent environment variables. Don't attempt to modify the supposedly-const argument to putenv() Fix an off-by-one sizing error in the zipfs code detected by the new allocator.
