* asm-generic: make pci.h usable directlyArnd Bergmann2009-06-112-12/+3
| | | | | | | | | | Some generic code is using the horribly misnamed PCI_DMA_BUS_IS_PHYS from asm/pci.h. This makes sure that an architecture without PCI support does not have to define this itself but can rely on the asm-generic version.

* asm-generic: rename page.h and uaccess.hArnd Bergmann2009-06-1123-23/+23
| | | | | | | | | | | | The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

* asm-generic: rename atomic.h to atomic-long.hArnd Bergmann2009-06-1123-23/+23
| | | | | | | | | | | The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

* asm-generic: introduce asm/bitsperlong.hArnd Bergmann2009-06-1128-46/+107
| | | | | | | | | | | | | | | | | | | This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

| | | | | | | | | | The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outlining fixes the issue were on certain CPUs such as the R10000 family the delay loop would need an extra cycle if it overlaps a cacheline boundary. The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever an erratum workaround is enabled, it will be applied whether or not the erratum is relevent for the CPU. This patch changes this - we check the variant and revision fields in the main ID register to determine which errata to apply. We also avoid re-applying erratum 460075 if it has already been applied. Applying this fix in non-secure mode results in the kernel failing to boot (or even do anything.) This fixes booting on some ARMv7 based platforms which otherwise silently fail.

Since operand lengths other than 32bit are required, the full implementations are only available if the ARMv6K extensions are present (for the LDREXB, LDREXH and LDREXD instructions). For ARMv6, only 32-bits cmpxchg is available. Mathieu : Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes). Make cmpxchg64_local always available. Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does. Change since v3 : - Add "memory" clobbers (thanks to Nicolas Pitre) - removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+. Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not supported by the Linux kernel currently. Put back arm < v6 cmpxchg support.
