* sh: intc - rework core codeMagnus Damm2007-09-213-214/+330
| | | | | | | | | | | | | | | | | This patch reworks the intc core, implementing the following features: - Support dual priority registers - one set and one clear register - All 8/16/32 bit register combinations are now supported - Both single mask and single enable bitmap register are supported - Add code to set interrupt priority - Speedup sense and priority configuration code - Allocate data using bootmem, allows intc data structures to be __initdata - Save memory - allocated memory footprint is smaller than intc structures Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - add a clear register to struct intc_prio_regMagnus Damm2007-09-2111-97/+105

* sh: intc - convert voyagergx codeMagnus Damm2007-09-214-143/+95
| | | | | | | | | | | | | | | | | | | | This patch converts the sh-specific voyagergx interrupt code to make use of intc. A lot of "interesting" old cruft gets replaced with intc tables and some simple demux code. - All interrupt sources in the sm501 data sheet are now in the header. - The number and order of IRQ values are disconnected from register bits. - Interrupt sources now start from IRQ 200. - set_irq_chained_handler() is now used to hook up the demux function. In the future it would probably make sense to move the interrupt demuxer into into the mfd driver, but this is probably a nice step in the right direction until that happens. Tested on a R2D-1 board using the serial port hooked up to the sm501. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - add single bitmap register supportMagnus Damm2007-09-212-11/+63
| | | | | | | | | | | | This patch adds single bitmap register support to intc. The current code only handles 16 and 32 bit registers where a set bit means interrupt enabled, but this is easy to extend in the future. The INTC_IRQ() macro is also added to provide a way to hook in interrupt controllers for FPGAs in boards or companion chips.

* sh: intc - remove redundant irq code for sh03, snapgear and titanMagnus Damm2007-09-218-109/+19
| | | | | | | | | | | | | | This patch removes redundant board specific interrupt code for boards using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode" aka IRLM. Three boards are affected: sh03, snapgear and titan. The right way to do this is to use cpu specific code provided by intc. A nice side effect is that sh03 now compiles, board not BROKEN any more.

* rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712.Paul Mundt2007-09-214-21/+58
| | | | | | | | | | | | | | All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.

* sh: intc - add support for SH7706, SH7707, SH7708, SH7709Magnus Damm2007-09-215-194/+220
| | | | | | | | | | | | | | | | | | | This patch unifies the cpu specific interrupt setup code for sh7706, sh7707, sh7708 and sh7709 and moves the code into a new file called setup-sh770x.c. It makes sense to share the setup code between these processors because most hardware blocks are identical from a software point of view. With this patch the sh770x processors now have a complete set of vectors that match with the information provided by the data sheets. This is a big improvement for sh7708. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also unifies the platform device setup code which means that the rtc driver now has platform data for all sh770x processors.

* | signalfd simplificationDavide Libenzi2007-09-208-217/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies signalfd code, by avoiding it to remain attached to the sighand during its lifetime. In this way, the signalfd remain attached to the sighand only during poll(2) (and select and epoll) and read(2). This also allows to remove all the custom "tsk == current" checks in kernel/signal.c, since dequeue_signal() will only be called by "current". I think this is also what Ben was suggesting time ago. The external effect of this, is that a thread can extract only its own private signals and the group ones. I think this is an acceptable behaviour, in that those are the signals the thread would be able to fetch w/out signalfd.

(Note: there are two previous __svc_print_addr(sin, buf, sizeof(buf)) calls in this function, either of which would initialize buf correctly; but both are inside "if"'s and are not necessarily executed.

It also gets rid of skb2 we only need to preserve the original skb for congestion notification, which is only applicable for ppp_async and ppp_sync. The other semantic change made here is the removal of socket accounting for data tranmitted out of pppol2tp_xmit. The original code leaked any existing socket skb accounting. We could fix this by dropping the original skb owner. However, this is undesirable as the packet has not physically left the host yet. In fact, all other tunnels in the kernel do not account skb's passing through to their own socket. In partciular, ESP over UDP does not do so and it is the closest tunnel type to PPPoL2TP. So this patch simply removes the socket accounting in pppol2tp_xmit. The accounting still applies to control packets of course. I've also added a reminder that the outgoing checksum here doesn't work. I suppose existing deployments don't actually enable checksums.
