2011-07-25microblaze: exec: Remove redundant set_fs(USER_DS)Mathias Krause1-1/+0
The address limit is already set in flush_old_exec() so this set_fs(USER_DS) is redundant. Signed-off-by: Mathias Krause <minipli@googlemail.com>
2011-03-09microblaze: Remove r0_ram pointer and PTO alignmentMichal Simek1-1/+1
r0_ram pool was used for saving/restoring register content if hw exception happen. This poll was replaced by pt_pool_space with PT_SIZE size. Based on this change SAVE_STATE_ARG_SPACE was removed which caused that PTO offset is zero that's why is also removed. r0_ram space was used as scratchpad by v850. In early Microblaze Linux developing phase was this part of code blindly copied. Signed-off-by: Michal Simek <monstr@monstr.eu>
