commit 08f1c192c3c32797068bfe97738babb3295bbf42
Author: Muli Ben-Yehuda
Date: Sun Jul 22 00:23:39 2007 +0300x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
This patch introduces struct pci_sysdata to x86 and x86-64, and
converts the existing two users (NUMA, Calgary) to use it.This lays the groundwork for having other users of sysdata, such as
the PCI domains work.The Calgary bits are tested, the NUMA bits just look ok.
replaces pcibios_scan_root by pci_scan_bus_parented...
but in pcibios_scan_root we have a check about scanned busses.

This patch fixes the problem that kdump by INIT does not work if we use
makedumpfile. The problem is that after INIT is issued, 2nd kernel
starts and makedumpfile fails with the following error message./proc/vmcore doesn't contain vmcoreinfo.
'-x' or '-i' must be specified.makedumpfile Failed.
The cause of this problem is that kernel does not call
crash_save_vmcoreinfo. When kdump starts by panic or sysrq-trigger,
crash_save_vmcoreinfo is called by crash_kexec. But this function is not
called when kdump starts by INIT. The Attached patch fixes this.This patch just adds crash_save_vmcoreinfo into machine_kdump_on_init so
that crash_save_vmcoreinfo can be called when kdump starts by INIT.
I tested this patch with linux-2.6.25-rc9 and I confirmed it worked.Signed-off-by: Takao Indoh

There is a NUMA memory configuration issue in 2.6.24:
A 2-node machine of ours has got the following memory layout:
Node 0: 0 - 2 Gbytes
Node 0: 4 - 8 Gbytes
Node 1: 8 - 16 Gbytes
Node 0: 16 - 18 Gbytes"efi_memmap_init()" merges the three last ranges into one.
"register_active_ranges()" is called as follows:
efi_memmap_walk(register_active_ranges, NULL);
i.e. once for the 4 - 18 Gbytes range. It picks up the node
number from the start address, and registers all the memory for
the node #0."register_active_ranges()" should be called as follows to
make sure there is no merged address range at its entry:efi_memmap_walk(filter_memory, register_active_ranges);
"filter_memory()" is similar to "filter_rsvd_memory()",
but the reserved memory ranges are not filtered out.Signed-off-by: Zoltan Menyhart

The functions time_before, time_before_eq, time_after, and time_after_eq are
more robust for comparing jiffies against other values.So use the time_after() & time_before() macros, defined at linux/jiffies.h,
which deal with wrapping correctly[akpm@linux-foundation.org: coding-style fixes]

IA64's IOMMU implementation allocates memory areas spanning LLD's segment
boundary limit. It forces low level drivers to have a workaround to adjust
scatter lists that the IOMMU builds.We are in the process of making all the IOMMUs respect the segment boundary
limits to remove such work around in LLDs. This patch is for IA64's IOMMU.Signed-off-by: FUJITA Tomonori

Add kprobe-booster support on ia64.
Kprobe-booster improves the performance of kprobes by eliminating single-step,
where possible. Currently, kprobe-booster is implemented on x86 and x86-64.
This is an ia64 port.On ia64, kprobe-booster executes a copied bundle directly, instead of single
stepping. Bundles which have B or X unit and which may cause an exception
(including break) are not executed directly. And also, to prevent hitting
break exceptions on the copied bundle, only the hindmost kprobe is executed
directly if several kprobes share a bundle and are placed in different slots.
Note: set_brl_inst() is used for preparing an instruction buffer(it does not
modify any active code), so it does not need any atomic operation.Signed-off-by: Masami Hiramatsu

The sys_getpid() and sys_set_tid_address() behavior changed from
return current->tgid
to
struct pid *pid;
pid = current->pids[PIDTYPE_PID].pid;
return pid->numbers[pid->level].nr;But the fast system calls on ia64 still operate the old way. Patch them
appropriately to let ia64 work with pid namespaces. Besides, this is one more
step in deprecating of pid and tgid on task_struct.The fsys_getppid() is to be patched as well, but its logic is much
more complex now, so I will make it later.One thing I'm not 100% sure is the trick with the IA64_UPID_SHIFT. On order
to access the pid->level's element of an array I have to perform the following
calculationspid + sizeof(struct upid) * pid->level
The problem is that ia64 can only multiply float point registers, while all
the offsets I have in code are in rXX ones. Fortunately, the sizeof(struct
upid) is 32 bytes on ia64 (and is very unlikely to ever change), so the
calculations get simpler:pid + pid->level << 5
So, I introduce the IA64_UPID_SHIFT and use the shl instruction. I also
looked at how gcc compiles the similar place and found that it makes it with
shift as well. Is this OK to do so?Tested with ski emulator with 2.6.24 kernel, but fits 2.6.25-rc4 and
2.6.25-rc4-mm1 as well.Signed-off-by: Pavel Emelyanov

While it is convenient that we can invoke kdump by asserting INIT
via button on chassis etc., there are some situations that invoking
kdump on fatal MCA is not welcomed rather than rebooting fast without
dump.This patch adds a new flag 'kdump_on_fatal_mca' that is independent
from 'kdump_on_init' currently available. Adding this flag enable
us to turning on/off of kdump depend on the event, INIT and/or fatal
MCA. Default for this flag is to take the dump.Signed-off-by: Hidetoshi Seto

This attached patch significantly shrinks boot memory allocation on ia64.
It does this by not allocating per_cpu areas for cpus that can never
exist.In the case where acpi does not have any numa node description of the
cpus, I defaulted to assigning the first 32 round-robin on the known
nodes.. For the !CONFIG_ACPI I used for_each_possible_cpu().Signed-off-by: Robin Holt

A simple fix. The existing pernodesize reservation is not taking into
account a second array of pg_data_t structures. This is normally not
important because the PAGE_ALIGN macro reserves adequate space.I made the compute_pernodesize steps in the same order as the fill_pernode
steps to make the correlation more clear.Signed-off-by: Robin Holt

The patch defines kernel parameter "nptcg=". The parameter overrides max number
of concurrent global TLB purges which is reported from either PAL_VM_SUMMARY or
SAL PALO.Signed-off-by: Fenghua Yu
Signed-off-by: Tony Luck -
According to SDM2.2, Itanium supports multiple outstanding ptc.g instructions.
But current kernel function ia64_global_tlb_purge() uses a spinlock to serialize
ptc.g instructions issued by multiple processors. This serialization might have
scalability issue on a big SMP machine where many processors could purge TLB
in parallel.The patch fixes this problem by issuing multiple ptc.g instructions in
ia64_global_tlb_purge(). It also adds support for the "PALO" table to get
a platform view of the max number of outstanding ptc.g instructions (which
may be different from the processor view found from PAL_VM_SUMMARY).PALO specification can be found at: http://www.dig64.org/home/DIG64_PALO_R1_0.pdf

This patch does:
- Remove outdated comments (which someday I marked with "?").
- Reassemble instructions to fit them in fewer bundles.
- If McKinley Errata 9 workaround is not needed, the workaround
bundles will be patched out with NOPs. However it also not
needed to have a totally NOP bundle (nop * 3) before branch.As a result, this makes the code path 3 (or 2) bundles shorter
(and remove 1 unnecessary stop bit). It seems to be 1% faster.(10sec loop test, with nojitter @ Madison 1.5GHz x 4)
