| * | [Blackfin] arch: relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file ↵Mike Frysinger2008-04-232-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | where it actually gets used. relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used. this way when we change CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files rather than a whole bunch that implicitly include cplb.h. this will also remove the ability to clear the swapcount on the fly, but i really dont think that functionality is important. ultimate goal is for CONFIG_MEM_SIZE to go away and calculate this value on the fly based on what u-boot programmed for us.

| * | [Blackfin] arch: fix bug - when using trace buffer with CONFIG_MPU enabled.Bernd Schmidt2008-04-231-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a couple of problems with the way the trace buffer state is saved/restored in assembly. The DEBUG_HWTRACE_SAVE/RESTORE macros save a value to the stack, which is not immediately obvious; the CPLB exception code needed changes to load the correct value of the stack pointer. The other problem is that the SAVE/RESTORE macros weren't pushing and popping the value downwards on the stack, but rather moving it _upwards_, which is of course completely broken. We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in the error case of the CPLB handler.

Currently the only other arch that uses NOTES is i386, and the patch which added it also added PHDRS { text PT_LOAD FLAGS(5); /* R_E */ data PT_LOAD FLAGS(7); /* RWE */ note PT_NOTE FLAGS(0); /* ___ */ } and a few other modifications to use ":text" and ":data" to the linker script.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent irq cleanups for arch/arm/mach-integrator/time.c and drivers/char/mwave/tp3780i.c changed the request_irq() dev_id parameter, but neglected to change the matching free_irq() parameter, thus creating a bug upon irq de-registration. Given that the impetus for the changes is not yet accepted upstream, it is best to revert the irq cleanups. Mostly. A comment is added to time.c to reduce future confusion, of type that led to my time.c cleanup in the first place. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

In fact, we can see what trap it is sleeping in whatever the type. The utrace guys will use this. Based upon some discussions with Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>
