2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] unconditionally define __virt_to_phys and __phys_to_virtNicolas Pitre
There is no machine class overriding this. If non linear translations are implemented again for some machines then this could be restored at that time. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] remove bogus #ifdef CONFIG_HIGHMEM in show_pte()Nicolas Pitre
The restriction on !CONFIG_HIGHMEM is unneeded since page tables are currently never allocated with highmem pages, and actually disable PTE dump whenever highmem is configured. Let's have a dynamic test to better describe the current limitation instead. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] prevent the vmalloc cmdline argument from eating all memoryNicolas Pitre
Commit 8d5796d2ec6b5a4e7a52861144e63af438d6f8f7 allows for the vmalloc area to be resized from the kernel cmdline. Make sure it cannot overlap with RAM entirely. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] mem_init() cleanupsNicolas Pitre
Make free_area() arguments pfn based, and return number of freed pages. This will simplify highmem initialization later. Also, codepages, datapages and initpages are actually codesize, datasize and initsize. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] split highmem into its own memory bankNicolas Pitre
Doing so will greatly simplify the bootmem initialization code as each bank is therefore entirely lowmem or highmem with no crossing between those zones. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] rationalize memory configuration code some moreNicolas Pitre
Currently there are two instances of struct meminfo: one in kernel/setup.c marked __initdata, and another in mm/init.c with permanent storage. Let's keep only the later to directly populate the permanent version from arm_add_memory(). Also move common validation tests between the MMU and non-MMU cases into arm_add_memory() to remove some duplication. Protection against overflowing the membank array is also moved in there in order to cover the kernel cmdline parsing path as well.

2008-11-28[ARM] fix a couple clear_user_highpage assembly constraintsNicolas Pitre
In all cases the kaddr is assigned an input register even though it is modified in the assembly code. Let's assign a new variable to the modified value and mark those inline asm with volatile otherwise they get optimized away because the output variable is otherwise not used. Also fix a few conversion errors in copypage-feroceon.c and copypage-v4mc.c. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-27[ARM] clearpage: provide our own clear_user_highpage()Russell King
For similar reasons as copy_user_page(), we want to avoid the additional kmap_atomic if it's unnecessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-27[ARM] copypage: provide our own copy_user_highpage()Russell King
We used to override the copy_user_page() function. However, this is not only inefficient, it also causes additional complexity for highmem support, since we convert from a struct page to a kernel direct mapped address and back to a struct page again. Moreover, with highmem support, we end up pointlessly setting up kmap entries for pages which we're going to remap. So, push the kmapping down into the copypage implementation files where it's required. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-11-27[ARM] sa1100: match clock by dev_name(dev)Russell King

2008-11-27[ARM] pxa: don't pass a consumer clock name for devices with unique clocksRussell King

People often point to the Integrator/Versatile/Realview implementations to justify using the consumer name as the sole selector for clocks.

2008-11-27[ARM] remove memzero()Russell King
As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-11-20[IA64] Rationalize kernel mode alignment checkingTony Luck
Itanium processors can handle some misaligned data accesses. They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck <tony.luck@intel.com>
