| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FSVOtest in this case, since I don't have the hardware... However, all changes seen by gcc are actually - explicit cast to unsigned short in return expression of functions returning unsigned short - csum_fold() return type changed from unsigned int to __sum16 (unsigned short), same as for all other architecture and as net/* expects; expression actually returned is ((~(sum << 16)) >> 16) with sum being unsigned 32bit, so it's (a) going to fit into the range of unsigned short and (b) had been unsigned all along, so no sign expansion mess happened.

* [Blackfin] arch: fix gdb testing regressionBernd Schmidt2008-05-06
| | | | | | | | | | | | | | When transferring to IRQ5 from an exception, save SYSCFG in memory across the transfer and clear the trace bit. When we get a single step exception, check whether we can safely clear the trace bit in SYSCFG. We can (and should) clear it after the first instruction of the interrupt handler; the first insn saves SYSCFG to the stack in all handlers.

* unified (weak) sys_pipe implementationUlrich Drepper2008-05-03
| | | | | | | | | | | | | | | | | | | This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* i2c: Convert most new-style drivers to use module aliasingJean Delvare2008-04-29
| | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

* [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.
