Current get_e_source() returns pointer to an element of array.
However since it also progress consume counter, it is possible
that the element is overwritten by newly produced data before
the element is really consumed.
This patch changes get_e_source() to copy contents of the element
to address pointed by its caller. Once copied the element in
array can be consumed.
And relocate this function to more innocuous place.

Divide tricky for-loop into readable if-blocks.
The logic to set multi_error_valid (to force walking pci bus
hierarchy to find 2nd~ error devices) is changed too, to check
MULTI_{,_UN}COR_RCV bit individually and to force walk only when
it is required.
And rework setting e_info->severity for uncorrectable, not to use
magic numbers.

Return bool to indicate that the source device is found or not.
This allows us to skip calling aer_process_err_devices() if we can.
And move dev_printk for debug into this function.

This cleanup solves some minor naming issues by removing unuseful
function aer_delete_rootport() and by renaming disable_root_aer()
to aer_disable_rootport().
- Inconsistent location of alloc & free:
The struct rpc is allocated in aer_alloc_rpc() at aerdrv.c
while it is implicitly freed in aer_delete_rootport() at
aerdrv_core.c.
- Inconsistent function name:
It makes a bit confusion that aer_delete_rootport() is seemed
to be paired with aer_enable_rootport(), i.e. there is neither
"add" against "delete" nor "disable" against "enable".

SuperIO devices share regions and use lock/unlock operations to chip
select. We therefore need to be able to request a resource and wait for
it to be freed by whichever other SuperIO device currently hogs it.
Right now you have to poll which is horrible.
Add a MUXED field to IO port resources. If the MUXED field is set on the
resource and on the request (via request_muxed_region) then we block
until the previous owner of the muxed resource releases their region.
This allows us to implement proper resource sharing and locking for
superio chips using code of the form
enable_my_superio_dev() {
request_muxed_region(0x44, 0x02, "superio:watchdog");
outb() ..sequence to enable chip
}
disable_my_superio_dev() {
outb() .. sequence of disable chip
release_region(0x44, 0x02);
}

Create convenience symlinks in sysfs, linking slots to device
functions, and vice versa. These links make it easier for users to
figure out which devices actually live in what slots.
For example:
sapphire:/sys/bus/pci/slots # ls
1 10 2 3 4 5 6 7 8 9
sapphire:/sys/bus/pci/slots # ls -l 3
total 0
-r--r--r-- 1 root root 65536 Aug 18 14:10 address
lrwxrwxrwx 1 root root 0 Aug 18 14:10 function0 ->
../../../../devices/pci0000:23/0000:23:01.0
lrwxrwxrwx 1 root root 0 Aug 18 14:10 function1 ->
../../../../devices/pci0000:23/0000:23:01.1
sapphire:/sys/bus/pci/slots # ls -l 3/function0/slot
lrwxrwxrwx 1 root root 0 Aug 18 14:13 3/function0/slot ->
../../../bus/pci/slots/3
The original form of this patch was written by Matthew Wilcox,
and was enhanced to include links from the sysfs slots/ directory
pointing back at the device functions.
