2006-12-06[PATCH] Clean up 'make help' output for documentation targets.Jesper Juhl1-3/+7
Here's a patch that cleans up the "make help" output a bit for the documentation targets. Currently the documentation targets are listed completely different than all the other targets : Documentation targets: Linux kernel internal documentation in different formats: xmldocs (XML DocBook), psdocs (Postscript), pdfdocs (PDF) htmldocs (HTML), mandocs (man pages, use installmandocs to install) with this patch they are more in line with the rest of the output : Documentation targets: Linux kernel internal documentation in different formats: htmldocs - HTML installmandocs - install man pages generated by mandocs mandocs - man pages pdfdocs - PDF psdocs - Postscript xmldocs - XML DocBook Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Acked-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Any code that relies on the volatile would be a bug waiting to happen anyway. Don't encourage people to think that putting 'volatile' on data structures somehow fixes problems.

2006-12-06[MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu23-231/+14
__do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

2006-12-06[PATCH] uclinux: fix mmap() of directory for nommu caseMike Frysinger1-5/+7
I was playing with blackfin when i hit a neat bug ... doing an open() on a directory and then passing that fd to mmap() would cause the kernel to hang after poking into the code a bit more, i found that mm/nommu.c:validate_mmap_request() checks the length and if it is 0, just returns the address ... this is in stark contrast to mmu's mm/mmap.c:do_mmap_pgoff() where it returns -EINVAL for 0 length requests ... i then noticed that some other parts of the logic is out of date between the two funcs, so perhaps that's the easy fix ?

2006-12-06sh: sh775x/titan fixes for irq header changes.Jamie Lenehan10-159/+165
The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

2006-12-06sh: Fixup movli.l/movco.l atomic ops for gcc4.Paul Mundt1-24/+24

2006-12-06sh: dyntick infrastructure.Paul Mundt3-1/+162

2006-12-06sh: Clock framework tidying.Paul Mundt9-23/+38

2006-12-06sh: Turn off IRQs around get_timer_offset() calls.Paul Mundt4-29/+12
Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Get the PGD right in oops case with 64-bit PTEs.Paul Mundt1-4/+2
Previously this was using a static pgd shift in the reporting code, simply flip this to PGDIR_SHIFT which does the right thing depending on varying PTE magnitudes on the SH-X2 MMU. While we're at it, and since it's been recently added, use get_TTB() for fetching the TTB, rather than the open coded instructions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Fix store queue bitmap end.Paul Mundt1-6/+5
The end of the store queue bitmap is miscalculated when searching for a free range in sq_remap(), missing the PAGE_SHIFT shift that's done in sq_api_init(). This runs in to workloads where we can scan beyond the end of the bitmap.

2006-12-06sh: More flexible + SH7780 earlyprintk SCIF support.Paul Mundt3-24/+39
This makes the early printk support somewhat more flexible, moving the port definition to a config option, and making the port initialization configurable for sh-ipl+g users. At the same time, this allows us to trivially wire up the SH7780 SCIF0, so that's thrown in too more or less for free. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Fixup various PAGE_SIZE == 4096 assumptions.Paul Mundt11-45/+37
There were a number of places that made evil PAGE_SIZE == 4k assumptions that ended up breaking when trying to play with 8k and 64k page sizes, this fixes those up. The most significant change is the way we load THREAD_SIZE, previously this was done via: mov #(THREAD_SIZE >> 8), reg shll8 reg to avoid a memory access and allow the immediate load. With a 64k PAGE_SIZE, we're out of range for the immediate load size without resorting to special instructions available in later ISAs (movi20s and so on). The "workaround" for this is to bump up the shift to 10 and insert a shll2, which gives a bit more flexibility while still being much cheaper than a memory access.

2006-12-06sh: Fixup 4K irq stacks.Paul Mundt1-7/+18

2006-12-06sh: dma-api channel capability extensions.Mark Glaisher2-96/+218
This extends the SH DMA API for allowing handling of DMA channels based off of their respective capabilities.

2006-12-06sh: Drop name overload in dma-sh.Paul Mundt1-8/+1
Pass along the dev_id from request_dma() all the way down, rather than inserting an artificial name relating to the TEI line that we were doing before. This makes the line a bit less obvious, but dev_id is the proper behaviour for this regardless. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Make dma-isa depend on ISA_DMA_API.Paul Mundt1-2/+2
