ia64: remove support for machvecs

2019-08-16T21:32:26Z

The only thing remaining of the machvecs is a few checks if we are running on an SGI UV system. Replace those with the existing is_uv_system() check that has been rewritten to simply check the OEM ID directly. That leaves us with a generic kernel that is as fast as the previous DIG/ZX1/UV kernels, but can support all hardware. Support for UV and the HP SBA IOMMU is now optional based on new config options.

ia64: remove now unused machvec indirections

2019-08-16T18:33:57Z

With the SGI SN2 machvec removal most of the indirections are unused now, so remove them. This includes the entire removal of the mmio read*/write* macros as the generic ones are identical to the asm-generic/io.h version.

Merge branch 'akpm' (Andrew's patch-bomb)

2012-03-29T00:19:28Z

Merge third batch of patches from Andrew Morton: - Some MM stragglers - core SMP library cleanups (on_each_cpu_mask) - Some IPI optimisations - kexec - kdump - IPMI - the radix-tree iterator work - various other misc bits.

I still have ~10 patches for 3.4, will send those along when they've baked a little more." * emailed from Andrew Morton : (35 commits) backlight: fix typo in tosa_lcd.c crc32: add help text for the algorithm select option mm: move hugepage test examples to tools/testing/selftests/vm mm: move slabinfo.c to tools/vm mm: move page-types.c from Documentation to tools/vm selftests/Makefile: make `run_tests' depend on `all' selftests: launch individual selftests from the main Makefile radix-tree: use iterators in find_get_pages* functions radix-tree: rewrite gang lookup using iterator radix-tree: introduce bit-optimized iterator fs/proc/namespaces.c: prevent crash when ns_entries[] is empty nbd: rename the nbd_device variable from lo to nbd pidns: add reboot_pid_ns() to handle the reboot syscall sysctl: use bitmap library functions ipmi: use locks on watchdog timeout set on reboot ipmi: simplify locking ipmi: fix message handling during panics ipmi: use a tasklet for handling received messages ipmi: increase KCS timeouts ipmi: decrease the IPMI message transaction time in interrupt mode ...

arch/ia64: remove references to cpu_*_map

2012-03-29T00:14:36Z

This was marked as obsolete for quite a while now.. Now it is time to remove it altogether. And while doing this, get rid of first_cpu() as well. Also, remove the redundant setting of cpu_online_mask in smp_prepare_cpus() because the generic code would have already set cpu 0 in cpu_online_mask. Reported-by: Tony Luck Signed-off-by: Srivatsa S.

[IA64] eliminate race condition in smp_flush_tlb_mm

2010-12-28T22:06:21Z

A race condition exists within smp_call_function_many() when called from smp_flush_tlb_mm(). On rare occasions the cpu_vm_mask can be cleared while smp_call_function_many is executing, occasionally resulting in a hung process. Make a copy of the mask prior to calling smp_call_function_many(). Signed-off-by: Dimitri Sivanich Signed-off-by: Tony Luck

ia64: convert last user of smp_call_function_mask
