2006-09-27[ARM] nommu: allows to support module in nommuHyok S. Choi
A simple patch to support module in nommu mode. The vmalloc is used instead of __vmalloc_area which depends on CONFIG_MMU. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] do_bad_area() always takes current and current->active_mmRussell King
Since do_bad_area() always takes the currently active task and (supposed to) take the currently active MM, there's no point passing them to this function. Instead, obtain references to them inside do_bad_area(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Add setup_mm_for_reboot() for nommuRussell King
Add an empty setup_mm_for_reboot() function for nommu machines. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Rename mm-armv.c to pgd.cRussell King
mm-armv.c now only contains the pgd allocation/freeing code, so rename it to have a more sensible filename. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Move rest of MMU setup code from mm-armv.c to mmu.cRussell King
If we're going to have mmu.c for code which is specific to the MMU machines, we might as well move the other MMU initialisation specific code from mm-armv.c into this new file. This also allows us to make some functions static. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Split ARM MM initialisation for !mmuRussell King
Move the MMU specific code from init.c into mmu.c, and add nommu fixups to nommu.c Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Separate page table manipulation code from bootmem initialisationRussell King
nommu does not require the page table manipulation code in the bootmem initialisation paths. Move this into separate inline functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] 3860/1: Versatile PCI config byte accessesPaul Brook
The ARM Versatile board PCI config space read routines are broken for byte accesses. The access uses a byte read, so masking the bottom two bits of the address is wrong. I guess this is a cut/paste error from the the halfword code which uses aligned word access+shift+mask.

2006-09-27[ARM] 3859/1: Fix devicemaps_init() XIP_KERNEL odd 1MiB XIP_PHYS_ADDR ↵George G. Davis
translation error The ARM XIP_KERNEL map created in devicemaps_init() is wrong. The map.pfn is rounded down to an even 1MiB section boundary which results in va/pa translations errors when XIP_PHYS_ADDR starts on an odd 1MiB boundary and this causes the kernel to hang. This patch fixes ARM XIP_KERNEL translation errors for the odd 1MiB XIP_PHYS_ADDR boundary case. Signed-off-by: George G. Davis <gdavis@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] 3858/1: S3C2412: power management codeBen Dooks
Add S3C2412 power management code, and move the core register saving in from s3c2412.c Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] 3854/2: S3C2410 - add machine type for AML M5900 series (resubmitted)David Anders
Add the AML M5900 series to the list of supported machines in the arch/arm/mach-s3c2410 directory. This ensures the core peripherals are registered, and the timer source is configured. if selected in the kernel config the framebuffer registers and mtd partition information are set. This version of the patch has corrected formatting and removed the legacy procfs directory entry.

2006-09-25[ARM] 3838/1: ARM: DCC debug console support for ARM11Tony Lindgren

2006-09-25[ARM] Cleanups for 4cc9bd2eaa1063c68341c1c00e66660adcfdf254Russell King
- Document the meaning for OP_SCALAR, OP_SD and add OP_DD. - Formatting cleanups - Remove now redundant code for making compare instructions operate on scalar values. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-25[ARM] 3789/4: Fix VFP emulation to ignore VECITR for scalar instructionGen FUKATSU
VECITR in Floating-Point Exception register indicates the number of remaining short vector iterations after a potential exception was detected. In case of exception caused by scalar instructions, VECITR is NOT updated. Therefore emulation for VFP must ignore VECITR field and treat "veclen" as zero when recognizing scalar instructing.

2006-09-25[ARM] 3792/2: Fix description of ZBOOT_ROM_BSSDan Fandrich
The documentation for the ZBOOT_ROM_BSS config option describes it as "The base address of 64KiB of read/write memory in the target for the ROM-able zImage..." In actuality, it requires more than 100 KiB of space in addition to enough space to hold the decompressed kernel. This patch fixes the description in the Kconfig file.

2006-09-25[ARM] 3853/1: Fix flush_ptrace_access() thinko for nonaliasing VIPT cache caseGeorge G. Davis
Fix thinko in the flush_ptrace_access() "if (expr)" for the ARM VIPT non-aliasing cache case. We only need to flush cache when VM_EXEC is set in vma->vm_flags but "if (expr) always evaluates to true on UP systems for the ARM VIPT non-aliasing cache case. Signed-off-by: George G. Davis <gdavis@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-09-25[ARM] 3832/1: iop3xx: coding style cleanupLennert Buytenhek
Since the iop32x code isn't iop321-specific, and the iop33x code isn't iop331-specfic, do a s/iop321/iop32x/ and s/iop331/iop33x/, and tidy up the code to conform to the coding style guidelines somewhat better.

2006-09-25[ARM] 3830/1: iop3xx: board support file cleanupLennert Buytenhek
Revamp the iop3xx board support: move the support code for each iop board type into its own file, start using platform serial and platform physmap flash devices, switch to a per-board time tick rate, and get rid of the ARCH_EP80219 and STEPD config options by doing the relevant checks at run time.

Add CP6 enable/disable sequences to the timekeeping code and the IRQ code. As a result, we can't depend on CP6 access being enabled when we enter get_irqnr_and_base anymore, so switch the latter over to using memory-mapped accesses for now.

2006-09-25[ARM] 3814/1: move 80200 dma_inv_range() erratum check out of lineLennert Buytenhek
On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't clear the dirty bits, which means that if we invalidate a dirty line, the dirty data can still be written back to memory later on. To work around this, dma_inv_range() on these two processors is implemented as dma_flush_range() (i.e. do a clean D-cache line before doing the invalidate D-cache line.) For this, we currently have a processor ID check in xscale_dma_inv_range(), but a better solution is to add a separate cache_fns and proc_info for A0/A1 80200.

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.
