x86: remove static boot_cpu_pda array v2
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* Remove the boot_cpu_pda array and pointer table from the data section.
Allocate the pointer table and array during init. do_boot_cpu()
will reallocate the pda in node local memory and if the cpu is being
brought up before the bootmem array is released (after_bootmem = 0),
then it will free the initial pda. This will happen for all cpus
present at system startup.
This removes 512k + 32k bytes from the data section.
For inclusion into sched-devel/latest tree.

* Restore the nodenumber field in the x86_64 pda. This field is slightly
different than the x86_cpu_to_node_map mainly because it's a static
indication of which node the cpu is on while the cpu to node map is a
dyanamic mapping that may get reset if the cpu goes offline. This also
simplifies the numa_node_id() macro.

* Introduce a new PER_CPU macro called "EARLY_PER_CPU". This is
used by some per_cpu variables that are initialized and accessed
before there are per_cpu areas allocated.
["Early" in respect to per_cpu variables is "earlier than the per_cpu
areas have been setup".]
This patchset adds these new macros:
DEFINE_EARLY_PER_CPU(_type, _name, _initvalue)
EXPORT_EARLY_PER_CPU_SYMBOL(_name)
DECLARE_EARLY_PER_CPU(_type, _name)
early_per_cpu_ptr(_name)
early_per_cpu_map(_name, _idx)
early_per_cpu(_name, _cpu)
The DEFINE macro defines the per_cpu variable as well as the early
map and pointer. It also initializes the per_cpu variable and map
elements to "_initvalue". The early_* macros provide access to
the initial map (usually setup during system init) and the early
pointer. This pointer is initialized to point to the early map
but is then NULL'ed when the actual per_cpu areas are setup. After
that the per_cpu variable is the correct access to the variable.
The early_per_cpu() macro is not very efficient but does show how to
access the variable if you have a function that can be called both
"early" and "late". It tests the early ptr to be NULL, and if not
then it's still valid. Otherwise, the per_cpu variable is used
instead:
#define early_per_cpu(_name, _cpu) \
(early_per_cpu_ptr(_name) ? \
early_per_cpu_ptr(_name)[_cpu] : \
per_cpu(_name, _cpu))
A better method is to actually check the pointer manually. In the
case below, numa_set_node can be called both "early" and "late":
void __cpuinit numa_set_node(int cpu, int node)
{
int *cpu_to_node_map = early_per_cpu_ptr(x86_cpu_to_node_map);
if (cpu_to_node_map)
cpu_to_node_map[cpu] = node;
else
per_cpu(x86_cpu_to_node_map, cpu) = node;
}
* Add a flag "arch_provides_topology_pointers" that indicates pointers
to topology cpumask_t maps are available. Otherwise, use the function
returning the cpumask_t value. This is useful if cpumask_t set size
is very large to avoid copying data on to/off of the stack.
* The coverage of CONFIG_DEBUG_PER_CPU_MAPS has been increased while
the non-debug case has been optimized a bit.
* Remove an unreferenced compiler warning in drivers/base/topology.c
* Clean up #ifdef in setup.c

Ok, I think I found it. In check_nmi_watchdog():
for (cpu = 0; cpu < NR_CPUS; cpu++)
prev_nmi_count[cpu] = cpu_pda(cpu)->__nmi_count;
As I mentioned it works fine on both of my systems so could you try it out?

The build of the Alpha Linux kernel currently fails[1] with inconsistent
kallsyms data. As I never saw that before, I thought about hardware
problems. But in fact it is a bug in the Linux kernel.
The end of the rodata section is marked with the "__end_rodata" symbol.
This symbol have different aligning constraints than the inittext parts
and therefor the start marked "_sinittext". Because of that the
__end_rodata symbol shifts between < _sinittext and == _sinittext. The
later variant is seen as a code symbol and recorded in the kallsyms data.
On fix would be to move the exception table a little bit and get some
space between that two areas.

The EFI code appears to manage low mappings for itself when needed; but
like many before it, confuses PSE with PAE. So it has only been mapping
half the space it needed when PSE but not PAE. This remained unnoticed
until we moved the SMP zap_low_mappings() before
efi_enter_virtual_mode(). Presumably could have been noticed years ago

Vegard Nossum reported crashes during cpu hotplug tests:
http://marc.info/?l=linux-kernel&m=121413950227884&w=4
In function _cpu_up, the panic happens when calling
__raw_notifier_call_chain at the second time. Kernel doesn't panic when
calling it at the first time. If just say because of nr_cpu_ids, that's
not right.
By checking the source code, I found that function do_boot_cpu is the culprit.
Consider below call chain:
_cpu_up=>__cpu_up=>smp_ops.cpu_up=>native_cpu_up=>do_boot_cpu.
So do_boot_cpu is called in the end. In do_boot_cpu, if
boot_error==true, cpu_clear(cpu, cpu_possible_map) is executed. So later
on, when _cpu_up calls __raw_notifier_call_chain at the second time to
report CPU_UP_CANCELED, because this cpu is already cleared from
cpu_possible_map, get_cpu_sysdev returns NULL.
Many resources are related to cpu_possible_map, so it's better not to
change it.
Below patch against 2.6.26-rc7 fixes it by removing the bit clearing in
cpu_possible_map.

Initialize the lock of bad_irq_desc properly.
The content of irq_desc array is replaced by bad_irq_desc in blackfin
arch irqchip init code. So, do it properly as common irq init code.

This patch updates the kvm host code to use the pvclock structs
and functions, thereby making it compatible with Xen.
The patch also fixes an initialization bug: on SMP systems the
per-cpu has two different locations early at boot and after CPU
bringup. kvmclock must take that in account when registering the
physical address within the host.
