* cross-arch: don't corrupt personality flags upon exec()Jiri Kosina2012-10-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec862ea ("[S390] Do not clobber personality flags on exec") and 59e4c3a2fe9c ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).

* microblaze: Switch ELF_ARCH code to 189Edgar E. Iglesias2011-10-141-3/+5

* microblaze: Add support for little-endian MicroblazeMichal Simek2010-10-211-1/+1
| | | | | | | | | | | | | Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.

* microblaze: Allow PAGE_SIZE configurationSteven J. Magnani2010-08-041-1/+1

* elf: kill USE_ELF_CORE_DUMPChristoph Hellwig2009-12-161-1/+0
| | | | | | | | | | | | | Currently all architectures but microblaze unconditionally define USE_ELF_CORE_DUMP. The microblaze omission seems like an error to me, so let's kill this ifdef and make sure we are the same everywhere.
