2006-04-28[PATCH] powerpc: Wire up *at syscallsAndreas Schwab
Wire up *at syscalls. This patch has been tested on ppc64 (using glibc's testsuite, both 32bit and 64bit), and compile-tested for ppc32 (I have currently no ppc32 system available, but I expect no problems).

This patch adds workaround for PPC 440GX erratum 440_43. According to this erratum spurious MachineChecks (caused by L1 cache parity) can happen during DataTLB miss processing.

2006-04-28[PATCH] powerpc: Use check_legacy_ioport() on ppc32 too.David Woodhouse
Some people report that we die on some Macs when we are expecting to catch machine checks after poking at some random I/O address. I'd seen it happen on my dual G4 with serial ports until we fixed those to use OF, but now other users are reporting it with i8042. This expands the use of check_legacy_ioport() to avoid that situation even on 32-bit kernels. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-04-28[PATCH] powerpc64: Fix loading of modules without a .toc sectionAlan Modra
Normally, ppc64 module .ko files contain a table-of-contents (.toc) section, but if the module doesn't reference any static or external data or external procedures, it is possible for gcc/binutils to generate a .ko that doesn't have a .toc. Currently the module loader refuses to load such a module, since it needs the address of the .toc section to use in relocations. This patch fixes the problem by using the address of the .stubs section instead, which is an acceptable substitute in this situation. Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-04-28powerpc/pseries: Tell firmware our capabilities on new machinesPaul Mackerras
This adds code to call a new firmware method to tell the firmware what machines and capabilities (such as VMX/Altivec) we support. This will be needed on POWER5+ and POWER6 machines, and it has no effect on past and current machines. Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-04-28[PATCH] powerpc: Fix pagetable bloat for hugepagesDavid Gibson
At present, ARCH=powerpc kernels can waste considerable space in pagetables when making large hugepage mappings. Hugepage PTEs go in PMD pages, but each PMD page maps 256M and so contains only 16 hugepage PTEs (128 bytes of data), but takes up a 1024 byte allocation. With CONFIG_PPC_64K_PAGES enabled (64k base page size), the situation is worse. Now hugepage PTEs are at the PTE page level (also mapping 256M), so we store 16 hugepage PTEs in a 64k allocation. The PowerPC MMU already means that any 256M region is either all hugepage, or all normal pages. Thus, with some care, we can use a different allocation for the hugepage PTE tables and only allocate the 128 bytes necessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-04-27[IA64-SGI] - Reduce overhead of reading sn_topologyJack Steiner
MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology.

2006-04-26[PATCH] Remove __devinit and __cpuinit from notifier_call definitionsChandra Seetharaman
Few of the notifier_chain_register() callers use __init in the definition of notifier_call.

Few of the notifier_chain_register() callers use __devinitdata in the definition of notifier_block data structure. It is incorrect as the data structure should be available after the initializations (they do not unregister them during initializations).

This still races with other simultaneous alloc_iommu or free_iommu(size > 1) which both use bus-unlocked operations.
