This was added at a time when the compiler did a less than stellar job of optimizing out dead code. These days this tends to be less of a concern, so kill it all off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Presently this is conditionalized on sh, and disabled for sh64. Now that SH-5 ties in to the clock framework, the sh64 exception can be dropped. Additionally, ARM will want to use the same hooks once SH-Mobile G3 grows clock framework support, so switch these paths over to HAVE_CLK now. Once the H8 and ARM sh-sci users hook up HAVE_CLK, the driver can be switched over to having an outright dependency on it and the ifdefs can go away. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Since 43cc71ee, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial platform drivers, to re-enable auto loading. NOTE that Kconfig for some of these drivers doesn't allow modular builds, and thus doesn't match the driver source's unload support. Presumably their unload code is buggy and/or weakly tested...

This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The kgdb console code requires uart_set_options() and friends, which are only provided by the serial core when console support is enabled. These were sitting under CONFIG_SH_KGDB and resulted in a link error when console support wasn't enabled, work that by rolling the console routines under CONFIG_SH_KGDB_CONSOLE, which they should have been all along.

This adds preliminary support for the SH7785-based Highlander board. Some of the Highlander support code is reordered so that most of it can be reused directly.

The sh-sci sci_br_interrupt() handler was failing to call in to uart_handle_break(), which was something that only the SH-3 path was doing, fix that up. Additionally, SUPPORT_SYSRQ seems to have moved down too far, move it back to the top so uart_handle_break() and friends aren't no-ops. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This is the grungy swap all the occurrences in the right places patch that goes with the updates. At this point we have the same functionality as before (except that sgttyb() returns speeds not zero) and are ready to begin turning new stuff on providing nobody reports lots of bugs If you are a tty driver author converting an out of tree driver the only impact should be termios->ktermios name changes for the speed/property setting functions from your upper layers. If you are implementing your own TCGETS function before then your driver was broken already and its about to get a whole lot more painful for you so please fix it 8) Also fill in c_ispeed/ospeed on init for most devices, although the current code will do this for you anyway but I'd like eventually to lose that extra paranoia [akpm@osdl.org: bluetooth fix] [mp3@de.ibm.com: sclp fix] [mp3@de.ibm.com: warning fix for tty3270] [hugh@veritas.com: fix tty_ioctl powerpc build] [jdike@addtoit.com: uml: fix ->set_termios declaration] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Martin Peschke <mp3@de.ibm.com> Acked-by: Peter Oberparleiter <oberpar@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

David Howells authored
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
