* sh: Make sure AT_SYSINFO_EHDR is exposed to userspace in asm/auxvec.h.Paul Mundt2008-07-29
| | | | | | | | | Presently this is protected by a CONFIG_VSYSCALL ifdef so we don't inadvertently trigger the creation of the gate VMA on CPUs where we don't enable the vDSO, which is obviously not visible to userspace. Fix this up by adding in an ifndef __KERNEL__ check at the same time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix in commit 3650925893469ccb03dbcc6a440c5d363350f591 was addressing the case of a granted PR lock with waiting PR and CW locks. It's a special case that requires forcing a CW bast. However, that forced CW bast was incorrectly applying to a second condition where the granted lock was CW. So, the holder of a CW lock could receive an extraneous CW bast instead of a PR bast. This fix narrows the original special case to what was intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 64K SPU local store mapping feature is incompatible with the 64K huge pages support due to the inability of some parts of the memory management to differenciate between them while they use a different page table format. For now, disable 64K huge pages when CONFIG_SPU_FS_64K_LS, in the long run, this can be fixed by making this feature use the hugetlb page table format.

This isn't a very good default on some powermacs where both the FW and pmac_zilog will default to 38400. This fixes it to use the same logic as pmac_zilog to pick a default speed.

This is intended to be compatible at the userspace level with x86's implementation[1], hence some of the funny attribute names. The arrangement of cache info is not immediately intuitive, but (again) it's for compatibility's sake. The cache attributes exposed are: type (Data, Instruction, or Unified) level (1, 2, 3...) size coherency_line_size number_of_sets ways_of_associativity All of these can be derived on platforms that follow the OF PowerPC Processor binding. The code "publishes" only those attributes for which it is able to determine values; attributes for values which cannot be determined are not created at all.
