[ARM] 4388/1: no need for arm/mm mmap range checks for non-mmu

2007-05-20T18:36:14+00:00

We don't need valid_phys_addr_range() or valid_mmap_phys_addr_range()
for the !CONFIG_MMU case.

[ARM] mm 10: allow memory type to be specified with ioremap

2007-05-05T19:59:27+00:00

__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.

[PATCH] kill eth_io_copy_and_sum()

2007-02-09T17:14:07+00:00

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)*

2006-11-30T14:36:29+00:00

Since the last definitions of this macros have been removed, we
can remove the warnings in asm/io.h.

[PATCH] Consolidate check_signature

2006-10-11T18:14:23+00:00

There's nothing arch-specific about check_signature(), so move it to
.  Use a cross between the Alpha and i386 implementations as
the generic one.

[ARM] 3813/1: prevent >= 4G /dev/mem mmap()

2006-09-25T09:25:26+00:00

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() API

2006-01-09T19:23:11+00:00

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.
