2017-07-03binfmt_flat: flat_{get,put}_addr_from_rp() should be able to failAl Viro1-2/+13
on MMU targets EFAULT is possible here. Make both return 0 or error, passing what used to be the return value of flat_get_addr_from_rp() by reference. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2009-05-29flat: fix data sections alignmentOskar Schirmer1-1/+0
The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

2008-08-11sh: Provide a FLAT_PLAT_INIT() definition.Takashi YOSHII1-0/+7
SH needs this in order to make sure that r4 has a sane value at process entry time, which the libc expects has already been taken care of. Fixes random crashes in flat binaries. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-07-29sh: migrate to arch/sh/include/Paul Mundt1-0/+24
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
