No functional change; this converts loops that iterate from 0 to
PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the
pci_bus_for_each_resource() iterator instead.
This doesn't change the way resources are stored; it merely removes
dependencies on the fact that they're in a table.

Now that we return the new resource start position, there is no
need to update "struct resource" inside the align function.

We broke "acpi=ht" in 2.6.32 by disabling MADT parsing
for acpi=disabled. e5b8fc6ac1
This also broke systems which invoked acpi=ht via DMI blacklist.
acpi=ht is a really ugly hack,
but restore it for those that still use it.

In its <asm/elf.h> ia64 defines SET_PERSONALITY in a way that unconditionally
sets the personality of the current process to PER_LINUX, losing any flag bits
from the upper 3 bytes of current->personality. This is wrong. Those bits are
intended to be inherited across exec (other code takes care of ensuring that
security sensitive bits like ADDR_NO_RANDOMIZE are not passed to unsuspecting
setuid/setgid applications).

__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096
systems it hogs 16MB of memory. This is way too much for a quite
probably unused facility (only KVM uses dynamic TR registers).
Change to an array of pointers, and allocate entries as needed on
a per cpu basis. Change the name too as the __per_cpu_ prefix is
confusing (this isn't a classic <linux/percpu.h> type object).

This is a patch related to this discussion.
http://www.spinics.net/lists/linux-ia64/msg07605.html
When INIT is sent, ip/psr/pfs register is stored to the I-resources
(iip/ipsr/ifs registers), and they are copied in the min-state save
area(pmsa_{iip,ipsr,ifs}).
Therefore, in creating pt_regs at ia64_mca_modify_original_stack(),
cr_{iip,ipsr,ifs} should be derived from pmsa_{iip,ipsr,ifs}. But
current code copies pmsa_{xip,xpsr,xfs} to cr_{iip,ipsr,ifs}
when PSR.ic is 0.
finish_pt_regs(struct pt_regs *regs, const pal_min_state_area_t *ms,
unsigned long *nat)
{
(snip)
if (ia64_psr(regs)->ic) {
regs->cr_iip = ms->pmsa_iip;
regs->cr_ipsr = ms->pmsa_ipsr;
regs->cr_ifs = ms->pmsa_ifs;
} else {
regs->cr_iip = ms->pmsa_xip;
regs->cr_ipsr = ms->pmsa_xpsr;
regs->cr_ifs = ms->pmsa_xfs;
}
It's ok when PSR.ic is not 0. But when PSR.ic is 0, this could be
a problem when we investigate kernel as the value of regs->cr_iip does
not point to where INIT really interrupted.
At first I tried to change finish_pt_regs() so that it uses always
pmsa_{iip,ipsr,ifs} for cr_{iip,ipsr,ifs}, but Keith Owens pointed out
it could cause another problem if I change it.
>The only problem I can think of is an MCA/INIT

I confirmed he was right, so I decided to keep it as-is and to
save pmsa_{iip,ipsr,ifs} to ia64_sal_os_state for debugging.
An attached patch is just adding new members into ia64_sal_os_state to
save pmsa_{iip,ipsr,ifs}.

Previously, we tried to use IA64_DEF_FIRST_DEVICE_VECTOR (0x30) as the
IA64_IRQ_MOVE_VECTOR. However, we allocate other IRQs from the device
vector range, so there's no guarantee that IA64_DEF_FIRST_DEVICE_VECTOR
will still be available when we register IA64_IRQ_MOVE_VECTOR.
This patch statically allocates 0x30 for IA64_IRQ_MOVE_VECTOR and
removes it from the device vector range.
Without this patch, we crash on machines like the HP rx3600 that use
vector 48 (0x30) as the ACPI SCI interrupt:
