2007-11-07sh: Add a dummy vga.h.Paul Mundt
We have nothing to do here, but there are continually drivers that fail to build without it. Stub it in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix up PAGE_KERNEL_PCC() for nommu.Paul Mundt
PAGE_KERNEL_PCC() takes two arguments, which weren't reflected in the nommu case. Fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off __{copy,clear}_user_page().Paul Mundt
Now that copy_to_user_page()/copy_from_user_page() are wired up, we can drop the old __copy_xxx() implementations. Now that the page colouring scheme has changed via kmap_coherent(), we can avoid the flush in these specific helpers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Optimized copy_{to,from}_user_page() for SH-4.Paul Mundt
This moves copy_{to,from}_user_page() out-of-line on SH-4 and converts for the kmap_coherent() API. Based on the MIPS implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Wire up clear_user_highpage().Paul Mundt
With the kmap_coherent() API in place, this is trivial to implement, and lets us avoid the cache flush in certain cases. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off the remaining ST40 cruft.Paul Mundt
The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.

2007-11-07sh: remove PTRACE_O_TRACESYSGOOD from asm/ptrace.hMike Frysinger
The common linux/ptrace.h already defines PTRACE_O_TRACESYSGOOD so there is no need to have arches do it. This also keeps glibc-2.7 from breaking since it has an enum for the PTRACE_O_* flags. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-02sh: Decouple 4k and soft/hardirq stacks.Paul Mundt
While using separate IRQ stacks can cut down on stack consumption, many users can also use 4k stacks directly without the additional need of separate stacks for soft and hardirqs. With this split, we support the same rationale for 4KSTACKS as m68knommu, with the IRQSTACKS abstraction as per ppc64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-10-30sh: Correct pte_page() breakage.Paul Mundt
As noted by David: pte_page() is a macro defined as follows; include/asm-sh/pgtable.h #define pte_page(x) phys_to_page(pte_val(x)&PTE_PHYS_MASK) include/asm-sh/page.h #define phys_to_page(phys) (pfn_to_page(phys >> PAGE_SHIFT)) So as you can see the phys_to_page() macro doesn't wrap the 'phys' parameter in parentheses so we end up with; pte_val(x)&PTE_PHYS_MASK >> PAGE_SHIFT Which is not what we wanted as '>>' has a higher precedence than bitwise AND. I dug into the git repository and I believe this bug was added with this commit (104b8deaa5c0144cccfc7d914413ff80c7176af1); 2006-03-27 KAMEZAWA Hiroyuki [PATCH] unify pfn_to_page: sh pfn_to_page -#define phys_to_page(phys) (mem_map + (((phys)-__MEMORY_START) >> PAGE_SHIFT)) -#define page_to_phys(page) (((page - mem_map) << PAGE_SHIFT) + __MEMORY_START) +#define phys_to_page(phys) (pfn_to_page(phys >> PAGE_SHIFT)) +#define page_to_phys(page) (page_to_pfn(page) << PAGE_SHIFT) Reported-by: David ADDISON <david.addison@st.com> Reported-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-10-22Change table chaining layoutJens Axboe
Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get and set the page member. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT entries. So in the worst case, saved_auxv does not get an AT_NULL entry at the end. The saved_auxv array must be terminated with an AT_NULL entry.

2007-10-17Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle
dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch.

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on 32bit targets. GCC can be made to warn about usage of long long types with ISO C90 (-ansi), but only with -pedantic. You can write this in a way that even then it doesn't cause warnings, namely by: #ifdef __GNUC__ __extension__ typedef __signed__ long long __s64; __extension__ typedef unsigned long long __u64; #endif The __extension__ keyword in front of this switches off any pedantic warnings for this expression.

2007-10-16x86: optimize page faults like all other achitectures and kill notifier cruftChristoph Hellwig
x86(-64) are the last architectures still using the page fault notifier cruft for the kprobes page fault hook. This patch converts them to the proper direct calls, and removes the now unused pagefault notifier bits aswell as the cruft in kprobes.c that was related to this mess. I know Andi didn't really like this, but all other architecture maintainers agreed the direct calls are much better and besides the obvious cruft removal a common way of dealing with kprobes across architectures is important aswell.

2007-10-03sh: Make kgdb i-cache flushing less inept.Paul Mundt
kgdb had its own ranged I-cache flushing routine that attempted to duplicate the flush_icache_range() functionality, but managed to do an explicit D-cache writeback & invalidate twice on SH-4. This is a no-op for SH-3, and the flush_icache_range() semantics already do what kgdb was feebly attempting to do already, so just move over to that and kill off the wrapper.

2007-09-21sh: Add maple bus support for the SEGA Dreamcast.Adrian McMenamin
The Maple bus is SEGA's proprietary serial bus for peripherals (keyboard, mouse, controller etc). The bus is capable of some (limited) hotplugging and operates at up to 2 M/bits. Drivers of one sort or another existed/exist for 2.4 and a rudimentary port, which didn't support the 2.6 device driver model was also in existence. This driver - for the bus logic itself and for the keyboard (other drivers will follow) are based on the code and concepts of those old drivers but have lots of completely rewritten parts. I have the maple bus code as a built in now as that seems the sane and rational way to handle something like that - you either want the bus or you don't.

2007-09-21sh: Fix up extended mode TLB for SH-X2+ cores.Paul Mundt
The extended mode TLB requires both 64-bit PTEs and a 64-bit pgprot, correspondingly, the PGD also has to be 64-bits, so fix that up. The kernel and user permission bits really are decoupled in early cuts of the silicon, which means that we also have to set corresponding kernel permissions on user pages or we end up with user pages that the kernel simply can't touch (!). Finally, with those things corrected, really enable MMUCR.ME and correct the PTEA value (this simply needs to be the upper 32-bits of the PTE, with the size and protection bit encoding).
