2010-08-04CRIS: Fix alignment problem for older ldJesper Nilsson
CRISv10 uses a pretty old ld, which does not allow ALIGN(0), (It becomes . = 0;) so instead we align to 1 byte. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2010-08-04CRIS: Add config for pausing a seg-faulting processJesper Nilsson
Put it on a wait queue, so we can attach gdb to the process to debug it instead of just killing it. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

2010-08-04CRIS: Better handling of pinmux settingsJesper Nilsson
Depending on eth, eth_mido and geth fields in wr_hwprot, don't set corresponding pins on gpio port b to gpio mode. This avoids re-resetting the ethernet PHY should this already have been done. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

2010-08-04CRIS: gpio: don't call copy_to_user()/copy_from_user() while holding spinlocksJesper Nilsson
copy_to_user()/copy_from_user() must not be used with spinlocks held. Move locks inside each case so we have better control of when the locks are held. Also, since we use spinlocks, we don't need to hold the BKL, so remove it. Reported-by: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
