[ACPI / tables] d23117244a: WARNING: CPU: 0 PID: 0 at arch/x86/kernel/apic/apic_noop.c:102 noop_apic_read()
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://internal_merge_and_test_tree devel-catchup-201509260834
commit d23117244a466b3821824a9daf6c42cc4c90b12b
Author: Al Stone <al.stone(a)linaro.org>
AuthorDate: Wed Sep 16 17:26:41 2015 -0600

ACPI / tables: add in a bad_madt_entry() function to eventually replace the macro
The existing BAD_MADT_ENTRY macro only checks that the size of the data
structure for an MADT subtable matches the length entry in the subtable.
This is, unfortunately, not reliable. Nor, as it turns out, does it have
anything to do with what the length should be in any particular table.
We introduce the bad_madt_entry() function that uses a data set to
do some basic sanity checks on any given MADT subtable. Over time, as
the spec changes, we should just be able to add entries to the data set
to reflect the changes.
What the data set captures is the allowed MADT subtable length for each
type of subtable, for each revision of the specification. While there
is a revision number in the MADT that we should be able to use to figure
out the proper subtable length, it was not changed when subtables did.
And, while there is a major and minor revision in the FADT that could
also help, it was not always changed as the subtables changed either.
So, the data set captures for each published version of the ACPI spec
what the FADT revisions numbers should be, the corresponding MADT
revision number, and the subtable types and lengths that were defined
at that time.
The sanity checks done are:
-- is the length non-zero?
-- is the subtable type defined/allowed for the revision of
the FADT we're using?
-- is the subtable type defined/allowed for the revision of
the MADT we're using?
-- is the length entry what it should be for this revision
of the MADT and FADT?
These checks are more thorough than the previous macro provided, and
are now insulated from data structure size changes by ACPICA, which
have been the source of other patches in the past.
Now that the bad_madt_entry() function is available, we add code to
also invoke it before any subtable handlers are called to use the
info in the subtable. Subsequent patches will remove the use of the
BAD_MADT_ENTRY macro which is now redundant as a result. Any ACPI
functions that use acpi_parse_madt_entries() will always have all of
the MADT subtables checked from now on.

Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 991de2e59090e55c65a7f59a049142e3c480f7bd
Author: Jiang Liu <jiang.liu(a)linux.intel.com>
AuthorDate: Wed Jun 10 16:54:59 2015 +0800
Commit: Bjorn Helgaas <bhelgaas(a)google.com>
CommitDate: Thu Jul 30 14:05:57 2015 -0500
PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()
To support IOAPIC hotplug, we need to allocate PCI IRQ resources on demand
and free them when not used anymore.
Implement pcibios_alloc_irq() and pcibios_free_irq() to dynamically
allocate and free PCI IRQs.
Remove mp_should_keep_irq(), which is no longer used.
