| | | | | | | | | | | | | | | | kernel_text_address returns true even for modules which is not wanted in text_poke. Use core_kernel_text instead. This is a regression introduced in e587cadd8f47e202a30712e2906a65a0606d5865 which caused occasionaly crashes after suspend/resume.

| * | [Blackfin] arch: Remove the circular buffering mechanism for exceptionsBernd Schmidt2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the circular buffering mechanism for exceptions. Instead, point RETX at a safe location from which to fetch three NOPs. This safe location is now in the fixed code area, and also used for certain anomaly workarounds, to ensure that user space can find a valid ICPLB when things are built with CONFIG_MPU. Also, save I/DCPLB_FAULT_ADDRESS when lowering to level 5, since the hardware reg is valid only at exception level.

| * | [Blackfin] arch: This allows XIP to work with FD-PIC.Bernd Schmidt2008-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, init failed to do anything meaningful; it turns out that the reason is that FD-PIC has a readonly data section which can be located in the XIP filesystem, and various address checks in the kernel reject such addresses for syscall arguments. Hence, init's execve ("/bin/sh", ...) failed with error code EFAULT. There's room for improvement here: in case people want to have filesystems on flash rather than in main memory, _access_ok should be modified to allow this. This bug fix is also dedicated to Michael Hennerich. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Bryan Wu <cooloney@kernel.org>

| * | [Blackfin] arch: fix bug - a crash on bootup with CONFIG_MPU on the BF548Bernd Schmidt2008-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function flush_switched_dcplbs was clearing the CPLB entries covering the process permission bitmasks. This means that the sequence flush_switched_dcplbs (); set_mask_dcplbs(mm->context.page_rwx_mask); has a problem: if kernel code (such as an interrupt) causes a CPLB miss before set_mask_dcplbs completes, the CPLB handler function causes a double fault, with an instantaneous reboot. This bug fix is dedicated to Michael Hennerich, the only person in the world capable of providing working JTAG hardware.
