* KVM: ia64: fix vmm_spin_{un}lock for !CONFIG_SMPXiantao Zhang2008-11-11
| | | | | | | | In the case of !CONFIG_SMP, raw_spinlock_t is empty and the spinlock functions don't build. Fix by defining spinlock functions for the uniprocessor case. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>

* [IA64] Reserve elfcorehdr memory in CONFIG_CRASH_DUMPJay Lan2008-11-07
| | | | | | | | | | | | | | | | IA64 kdump kernel failed to initialize /proc/vmcore in 2.6.28-rc2. A bug was introduced in this patch commit: d9a9855d0b06ca6d6cc92596fedcc03f8512e062 always reserve elfcore header memory in crash kernel The problem was that the call to reserve_elfcorehdr() should be placed in CONFIG_CRASH_DUMP rather than in CONFIG_CRASH_KERNEL, which does not exist.

* [IA64] fix boot panic caused by offline CPUsDoug Chapman2008-11-06
| | | | | | | | | | | | | | | | | | | This fixes a regression introduced by 2c6e6db41f01b6b4eb98809350827c9678996698 "Minimize per_cpu reservations." That patch incorrectly used information about what CPUs are possible that was not yet initialized by ACPI. The end result was that per_cpu structures for offline CPUs were not initialized causing a NULL pointer reference. Since we cannot do the full acpi_boot_init() call any earlier, the simplest fix is to just parse the MADT for SAPIC entries early to find the CPU info. This should also allow for some cleanup of the code added by the "Minimize per_cpu reservations". This patch just fixes the regressions, the cleanup will come in a later patch.

* [IA64] fix the difference between node_mem_map and node_start_pfnKen'ichi Ohmichi2008-11-04
| | | | | | | | | | | | | | | | | | | | | | | | makedumpfile[1] cannot run on ia64 discontigmem kernel, because the member node_mem_map of struct pgdat_list has invalid value. This patch fixes it. node_start_pfn shows the start pfn of each node, and node_mem_map should point 'struct page' of each node's node_start_pfn. On my machine, node0's node_start_pfn shows 0x400 and its node_mem_map points 0xa0007fffbf000000. This address is the same as vmem_map, so the node_mem_map points 'struct page' of pfn 0, even if its node_start_pfn shows 0x400. The cause is due to the round down of min_pfn in count_node_pages() and node0's node_mem_map points 'struct page' of inactive pfn (0x0).

* saner FASYNC handling on file closeAl Viro2008-11-01
| | | | | | | | | | | | | | As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.
