| * RealView: Use only the shadow mapping of ARM11MPCore local timersCatalin Marinas2008-12-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | All the cases where the local timer for a CPU is accessed happen on the corresponding current CPU, hence no need to access the per-CPU local timer mappings. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

| * | [ARM] rationalize memory configuration code some moreNicolas Pitre2008-11-281-16/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [ARM] fix naming of MODULE_START / MODULE_ENDRussell King2008-11-061-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | As of 73bdf0a60e607f4b8ecc5aec597105976565a84f, the kernel needs to know where modules are located in the virtual address space. On ARM, we located this region between MODULE_START and MODULE_END. Unfortunately, everyone else calls it MODULES_VADDR and MODULES_END. Update ARM to use the same naming, so is_vmalloc_or_module_addr() can work properly. Also update the comment on mm/vmalloc.c to reflect that ARM also places modules in a separate region from the vmalloc space. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | [ARM] fix VFP+softfloat binariesRussell King2008-11-041-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.28-rc tightened up the ELF architecture checks on ARM. For non-EABI it only allows VFP if the hardware supports it. However, the kernel fails to also inspect the soft-float flag, so it incorrectly rejects binaries using soft-VFP. The fix is simple: also check that EF_ARM_SOFT_FLOAT isn't set before rejecting VFP binaries on non-VFP hardware.

Since the setup is a one-off initialization, we can be a little more clever and take account of the CPU architecture as well. Note that we continue to achieve the compactness on optimised kernels by forcing tests to always-false or always-true as appropriate, thereby allowing the compiler to do build-time code elimination.

| * | | [ARM] Remove cache type printksRussell King2008-09-251-141/+1Star

Currently, this code: a) doesn't work for everything - Xscale's are identified as 'unknown 5'. b) is not able to tell whether the caches are VIVT or VIPT from the cache type. c) prints rubbish on some ARMv6 and ARMv7+ CPUs. The two solutions to this are: 1. Add yet more code to decode and print the various different register formats. 2. Remove the code altogther. The code only exists to decode and print the cache parameters. Increasing the complexity of it just for the sake of a few prinks isn't worth it.

* / kgdb, x86, arm, mips, powerpc: ignore user space single steppingJason Wessel2008-09-261-2/+0Star
|/ | | | | | | | | | | | | | | | | | | | On the x86 arch, user space single step exceptions should be ignored if they occur in the kernel space, such as ptrace stepping through a system call. First check if it is kgdb that is executing a single step, then ensure it is not an accidental traversal into the user space, while in kgdb, any other time the TIF_SINGLESTEP is set, kgdb should ignore the exception. On x86, arm, mips and powerpc, the kgdb_contthread usage was inconsistent with the way single stepping is implemented in the kgdb core. The arch specific stub should always set the kgdb_cpu_doing_single_step correctly if it is single stepping. This allows kgdb to correctly process an instruction steps if ptrace happens to be requesting an instruction step over a system call. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap).

* / [ARM] Fix SMP booting with non-zero PHYS_OFFSETRussell King2008-08-071-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | The existing code tries to get the pmd for the temporary page table by doing: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd, PHYS_OFFSET); Since we have a two level page table, pmd_offset() is a no-op, so this just has a casting effect from a pgd to a pmd - the address argument is unused. So this can't work. Normally, we'd do: pgd = pgd_offset(&init_mm, PHYS_OFFSET); ... pmd = pmd_offset(pgd, PHYS_OFFSET); to get the pmd you want. However, pgd_offset() takes the mm_struct, not the (unattached) pgd we just allocated. So, instead use: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET); Reported-by: Antti P Miettinen <ananaza@iki.fi> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King2008-08-077-7/+7

* [ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King2008-08-071-1/+1
| | | | | | | | | Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h.
