* sparc: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-291-1/+0Star
| | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

| | | | | | | | | | | | | | | Machines with sun4c support are very rare these days, and noone is using them for any practical purposes. The sun4c support has been know broken for quite some time too. So rather than trying to keep it up-to-date, lets get rid of it. This allows us to do some very welcome cleanup of sparc32 support. Updated the former sun4c specifc nmi (which was also used for sun4m UP) to be a generic UP NMI. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc: Write to prom console using indirect buffer.David S. Miller2010-12-013-25/+48
| | | | | | | | | | | | | | | | | | | | | sparc64 systems have a restriction in that passing in buffer addressses above 4GB to prom calls is not reliable. We end up violating this when we do prom console writes, because we use an on-stack buffer to translate '\n' into '\r\n'. So instead, do this translation into an intermediate buffer, which is in the kernel image and thus below 4GB, then pass that to the PROM console write calls. On the 32-bit side we don't have to deal with any of these issues, so the new prom_console_write_buf() uses the existing prom_nbputchar() implementation. However we can now mark those routines static. Since the 64-bit side completely uses new code we can delete the putchar bits as they are now completely unused. Signed-off-by: David S.

* | Fix IRQ flag handling namingDavid Howells2010-10-071-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

* sparc64: Get rid of indirect p1275 PROM call buffer.David S. Miller2010-08-246-273/+453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is based upon a report by Meelis Roos showing that it's possible that we'll try to fetch a property that is 32K in size with some devices. With the current fixed 3K buffer we use for moving data in and out of the firmware during PROM calls, that simply won't work. In fact, it will scramble random kernel data during bootup. The reasoning behind the temporary buffer is entirely historical. It used to be the case that we had problems referencing dynamic kernel memory (including the stack) early in the boot process before we explicitly told the firwmare to switch us over to the kernel trap table. So what we did was always give the firmware buffers that were locked into the main kernel image. But we no longer have problems like that, so get rid of all of this indirect bounce buffering. Besides fixing Meelis's bug, this also makes the kernel data about 3K smaller. It was also discovered during these conversions that the implementation of prom_retain() was completely wrong, so that was fixed here as well. Currently that interface is not in use.

* sparc64: Fix bootup with mcount in some configs.David S. Miller2009-09-042-5/+4Star
| | | | | | | | | | | | | | | | | | | | | Functions invoked early when booting up a cpu can't use tracing because mcount requires a valid 'current_thread_info()' and TLB mappings to be setup. The code path of sun4v_register_mondo_queues --> register_one_mondo is one such case. sun4v_register_mondo_queues already has the necessary 'notrace' annotation, but register_one_mondo does not. Normally register_one_mondo is inlined so the bug doesn't trigger, but with some config/compiler combinations, it won't be so we must properly mark it notrace. While we're here, add 'notrace' annoations to prom_printf and prom_halt so that early error handling won't have the same problem.

* sparc32: More memory probing consolidation.David S. Miller2008-05-021-82/+62Star
| | | | | | | | | | | The PROM library function prom_meminit() builds a table, prom_phys_avail[], just so that probe_memory() in arch/sparc/mm/fault.c can copy it into sp_banks[]. Just have prom_meminit() fill in the sp_banks[] array directly, and remove duplicated sort() function. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Kill totally unused memory information tables.David S. Miller2008-05-021-99/+4Star
| | | | | | | | | | | | | The code in arch/sparc/prom/memory.c computes three tables, the list of total memory, the list of available memory (total minus what firmware is using), and the list of firmware taken memory. Only the available memory list is even used. Therefore, kill those unused tables and make prom_meminfo() return just the available memory list. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC]: Kill 'prom_palette'.David S. Miller2008-02-191-7/+0Star
| | | | | | | | | | | | | | The idea of this thing is we could save/restore the firmware's palette when breaking in and out of the firmware prompt. Only one driver implemented this (atyfb) and it's value is questionable. If you're just debugging you don't really care that the characters end up being purple or whatever. And we can provide better debugging and firmware command facilities with minimal in-kernel console I/O drivers. Signed-off-by: David S. Miller <davem@davemloft.net>
