2007-02-10[MIPS] signal: do not use save_static_function() anymoreFranck Bui-Huu
This macro was used to save static registers before calling sys_sigsuspend() and sys_sigreturn(). For the sys_sigreturn() case, there's no point to save them since they have been already saved by setup_sigcontext() before calling the signal handler. For the sys_sigsuspend() case, I don't see any reasons... Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-10[MIPS] signal32: no need to save c0_status register in setup_sigcontext32()Franck Bui-Huu
All the information in the MIPS c0_status register is priviledged. Nothing that would constitute part of the thread context. The one flag one could possibly argument about might be c0_status.fr but none of the ABIs or tools or application software can make use of it. So for consistency with restore_sigcontext32(), which does not restore c0_status register, this patch remove the saving part.

2007-02-10[MIPS] signal32: remove duplicate codeFranck Bui-Huu
There's no point for signal32.c to redefine get_sigframe(). It should use the one define in signal.c instead. The same stands for install_sigtramp(). Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-10[MIPS] signal: clean up sigframe structureFranck Bui-Huu
This patch makes 'struct sigframe' declaration avalaible for all signals code. It allows signal32 to not have its own declaration. This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in structure declaration and hopefully make them more readable.

2007-02-10[MIPS] signal: do not inline functions in signal-common.hFranck Bui-Huu
These functions are quite big and there are no points to make them inlined. So this patch moves the functions implementation in signal.c and make them available for others source files which need them.

2007-02-09[AVR32] Add PIOE device and reserve SDRAM pinsHaavard Skinnemoen
The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-02-09[AVR32] ext int fixesDavid Brownell
Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...
