kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

acpi_resource_parse() with &acpi_resource_parse_ops_default prints
resouce info and newline. Found and tested on ThinkPad X21.
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific
avoid calling the "_DIS" method during acpi interrupt link setup,
which hangs various nforce4 based motherboards.
when the problem is properly fixed, remove this hack. for now,
it allows someone (me) to have a valid kernel config that doesn't
require a source hack every new tree.
ok chs@
On one of my machines, there's no _GPE method, so
acpiec_parse_gpe_package fails, and the only function acpiec(4)
serves is to inhibit suspend/resume.
XXX We should really put the power handlers in the cfattach so that
it's not necessary to register a null power handler in every error
branch of every device's attach routine...
The four modules are apple_smc for the core functions, apple_smc_acpi
for attachment at acpi, and apple_smc_fan & apple_smc_temp for stuff
on the SMC.
Seems like there's a lot more bookkeeping necessary to maintain
children of an applesmc device implemented by loadable modules.
Maybe there's a better way I just haven't figured out yet.
Device interface derived by reading the Linux driver source code and
<http:///www.parhelia.ch/blog/statics/k3_keys.html> as of 2012-12-05.
Includes support for attaching fan and temperature sensors to sysmon.
No accelerometer yet.
Compile-tested only, based on some run-testing of experiments from
userland. Module attachment is not quite finished, so it won't work
yet.
