2018-03-09arch: remove m32r portArnd Bergmann1-143/+0
The Mitsubishi/Renesas m32r architecture has been around for many years, but the Linux port has been obsolete for a very long time as well, with the last significant updates done for linux-2.6.14. While some m32r microcontrollers are still being marketed by Renesas, those are apparently no longer possible to support, mainly due to the lack of an external memory interface. Hirokazu Takata was the maintainer until the architecture got marked Orphaned in 2014.

2017-08-31binfmt_flat: fix arch/m32r and arch/microblaze flat_put_addr_at_rp()Randy Dunlap1-1/+2
Change the m32r flat_put_addr_at_rp() function to return int and always return 0. The microblaze function already returned 0 so just change its function return type from void to int. Seven (7) other arch-es already have this function as returning an int type result.

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 <[email protected]>
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.
