* [ARM] 4388/1: no need for arm/mm mmap range checks for non-mmuGreg Ungerer2007-05-201-0/+2
| | | | | | | | We don't need valid_phys_addr_range() or valid_mmap_phys_addr_range() for the !CONFIG_MMU case. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] mm 10: allow memory type to be specified with ioremapRussell King2007-05-051-12/+21
| | | | | | | | | | | | | | __ioremap() took a set of page table flags (specifically the cacheable and bufferable bits) to control the mapping type. However, with the advent of ARMv6, this is far too limited. Replace the page table flags with a memory type index, so that the desired attributes can be selected from the mem_type table. Finally, to prevent silent miscompilation due to the differing arguments, rename the __ioremap() and __ioremap_pfn() functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [PATCH] kill eth_io_copy_and_sum()Al Viro2007-02-091-5/+0
| | | | | | | | | | | On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len). The function name is highly misguiding (it _never_ does any checksums), the last argument is just a noise and simply expanding the call to memcpy_fromio() gives shorter and more readable source. For a lot of reasons it has almost no remaining users, so it's better to just outright kill it.

* [ARM] Remove warnings for __io_pci and __arch_(get|put)*Russell King2006-11-301-8/+0

* [PATCH] Consolidate check_signatureMatthew Wilcox2006-10-111-17/+0
| | | | | | | | | | | There's nothing arch-specific about check_signature(), so move it to <linux/io.h>. Use a cross between the Alpha and i386 implementations as the generic one.

* [ARM] 3813/1: prevent >= 4G /dev/mem mmap()Lennert Buytenhek2006-09-251-0/+4
| | | | | | | | | | | | Prevent userland from mapping in physical address regions >= 4G by checking for that in valid_mmap_phys_addr_range(). Unfortunately, we cannot override valid_mmap_phys_addr_range() without also overriding valid_phys_addr_range(), so copy drivers/char/mem.c's version of valid_phys_addr_range() over to arch/arm/mm/mmap.c as well.

* [ARM] 3070/2: Add __ioremap_pfn() APIDeepak Saxena2006-01-091-0/+6
| | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena In working on adding 36-bit addressed supersection support to ioremap(), I came to the conclusion that it would be far simpler to do so by just splitting __ioremap() into a main external interface and adding an __ioremap_pfn() function that takes a pfn + offset into the page that __ioremap() can call. This way existing callers of __ioremap() won't have to change their code and 36-bit systems will just call __ioremap_pfn() and we will not have to deal with unsigned long long variables. Note that __ioremap_pfn() should _NOT_ be called directly by drivers but is reserved for use by arch_ioremap() implementations that map 32-bit resource regions into the real 36-bit address and then call this new function.

* [ARM] 3191/1: Mark I/O pointer as const in __raw_reads[bwl]Deepak Saxena2005-12-051-3/+3
| | | | | | | | | | | | Patch from Deepak Saxena Mark the ioremap'd cookie/pointer in said functions as const since we should not be actualy touching the data. This fixes a slew of compile warnings on IXP4xx as our reads[bwl] already mark this parameter as const.

* [ARM] __ioremap doesn't use 4th argumentRussell King2005-11-171-9/+12
| | | | | | | | The "align" argument in ARMs __ioremap is unused and provides a misleading expectation that it might do something. It doesn't. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | Patch from Lennert Buytenhek This patch conditionalises the io{read,write}{8,16,32} defines and the prototypes for ioport_map/ioport_unmap in asm-arm/io.h on ioread8 not already having been defined. This is done so that platforms can provide their own implementation of the iomap API, ixp2000 for example needs this.

* [PATCH] ARM: 2649/1: Fix 'sparse -Wbitwise' warnings from MMIO macrosOlav Kongas2005-04-291-10/+18
| | | | | | | | | | | | | | | | Patch from Olav Kongas On ARM, the outX() and writeX() families of macros take the result of cpu_to_leYY(), which is of restricted type __leYY, and feed it to __raw_writeX(), which expect an argument of unrestricted type. This results in 'sparse -Wbitwise' warnings about incorrect types in assignments. Analogous type mismatch warnings are issued for inX() and readX() counterparts. The below patch resolves these warnings by adding forced typecasts. Signed-off-by: Olav Kongas Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+286
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
