====================
ioc3-eth improvements
In my patch series for splitting out the serial code from ioc3-eth
by using a MFD device there was one big patch for ioc3-eth.c,
which wasn't really usefull for reviews. This series contains the
ioc3-eth changes splitted in smaller steps and few more cleanups.
Only the conversion to MFD will be done later in a different series.
Changes in v3:
- no need to check skb == NULL before passing it to dev_kfree_skb_any
- free memory allocated with get_page(s) with free_page(s)
- allocate rx ring with just GFP_KERNEL
- add required alignment for rings in comments
Changes in v2:
- use net_err_ratelimited for printing various ioc3 errors
- added missing clearing of rx buf valid flags into ioc3_alloc_rings
- use __func__ for printing out of memory messages

After allocation of descriptor memory is now done once in probe
handling of tx ring is completely done by ioc3_clean_tx_ring. So
we remove the remaining tx ring actions out of ioc3_alloc_rings
and ioc3_free_rings and rename it to ioc3_[alloc|free]_rx_bufs
to better describe what they are doing.

In register_ftrace_function_probe(), we are not checking the return
value of alloc_and_copy_ftrace_hash(). The subsequent call to
ftrace_match_records() may end up dereferencing the same. Add a check to
ensure this doesn't happen.

The test (ftrace_set_ftrace_filter.sh) is part of ftrace stress tests
and the crash happens when the test does 'cat
$TRACING_PATH/set_ftrace_filter'.
The address points to the second line below, in t_probe_next(), where
filter_hash is dereferenced:
hash = iter->probe->ops.func_hash->filter_hash;
size = 1 << hash->size_bits;
This happens due to a race with register_ftrace_function_probe(). A new
ftrace_func_probe is created and added into the func_probes list in
trace_array under ftrace_lock. However, before initializing the filter,
we drop ftrace_lock, and re-acquire it after acquiring regex_lock. If
another process is trying to read set_ftrace_filter, it will be able to
acquire ftrace_lock during this window and it will end up seeing a NULL
filter_hash.
Fix this by just checking for a NULL filter_hash in t_probe_next(). If
the filter_hash is NULL, then this probe is just being added and we can
simply return from here.

The subtraction of the two pointers is automatically scaled by the
size of the size of the object the pointers point to, so the division
by sizeof(*i2400m->barker) is incorrect. This has been broken since
day one of the driver and is only debug, so remove the debug completely.
Also move && in condition to clean up a checkpatch warning.

When counting dispatched micro-ops with cnt_ctl=1, in order to prevent
sample bias, IBS hardware preloads the least significant 7 bits of
current count (IbsOpCurCnt) with random values, such that, after the
interrupt is handled and counting resumes, the next sample taken
will be slightly perturbed.
The current count bitfield is in the IBS execution control h/w register,
alongside the maximum count field.
Currently, the IBS driver writes that register with the maximum count,
leaving zeroes to fill the current count field, thereby overwriting
the random bits the hardware preloaded for itself.
Fix the driver to actually retain and carry those random bits from the
read of the IBS control register, through to its write, instead of
overwriting the lower current count bits with zeroes.
Tested with:
perf record -c 100001 -e ibs_op/cnt_ctl=1/pp -a -C 0 taskset -c 0 <workload>

Tested on Family 15h and 17h machines.
Machines prior to family 10h Rev. C don't have the RDWROPCNT capability,
and have the IbsOpCurCnt bitfield reserved, so this patch shouldn't
affect their operation.
It is unknown why commit db98c5faf8cb ("perf/x86: Implement 64-bit
counter support for IBS") ignored the lower 4 bits of the IbsOpCurCnt
field; the number of preloaded random bits has always been 7, AFAICT.

The IP datasheet says this controller is compatible with SD Host
Specification Version v4.00.
As it turned out, the ADMA of this IP does not work with 64-bit mode
when it is in the Version 3.00 compatible mode; it understands the
old 64-bit descriptor table (as defined in SDHCI v2), but the ADMA
System Address Register (SDHCI_ADMA_ADDRESS) cannot point to the
64-bit address.
I noticed this issue only after commit bd2e75633c80 ("dma-contiguous:
use fallback alloc_pages for single pages"). Prior to that commit,
dma_set_mask_and_coherent() returned the dma address that fits in
32-bit range, at least for the default arm64 configuration
(arch/arm64/configs/defconfig). Now the host->adma_addr exceeds the
32-bit limit, causing the real problem for the Socionext SoCs.
(As a side-note, I was also able to reproduce the issue for older
kernels by turning off CONFIG_DMA_CMA.)
Call sdhci_enable_v4_mode() to fix this.

The OCR register defines the supported range of VDD voltages for SD cards.
However, it has turned out that some SD cards reports an invalid voltage
range, for example having bit7 set.
When a host supports MMC_CAP2_FULL_PWR_CYCLE and some of the voltages from
the invalid VDD range, this triggers the core to run a power cycle of the
card to try to initialize it at the lowest common supported voltage.
Obviously this fails, since the card can't support it.
Let's fix this problem, by clearing invalid bits from the read OCR register
for SD cards, before proceeding with the VDD voltage negotiation.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct spider_net_card {
...
struct spider_net_descr darray[0];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct spider_net_card) + (tx_descriptors + rx_descriptors) * sizeof(struct spider_net_descr)
with:
struct_size(card, darray, tx_descriptors + rx_descriptors)
Notice that, in this case, variable alloc_size is not necessary, hence it
is removed.
Building: allmodconfig powerpc.

====================
r8169: add support for RTL8125
This series adds support for the 2.5Gbps chip RTl8125. It can be found
on PCIe network cards, and on an increasing number of consumer gaming
mainboards. Series is partially based on the r8125 vendor driver.
Tested with a Delock 89531 PCIe card against a Netgear GS110MX
Multi-Gig switch.
Firmware isn't strictly needed, but on some systems there may be
compatibility issues w/o firmware. Firmware has been submitted to
linux-firmware.

- split first patch into 6 smaller ones to facilitate bisecting

This adds EEE support for RTL8125 based on the vendor driver.
Supported is EEE for 100Mbps and 1Gbps. Realtek recommended to not yet
enable EEE for 2.5Gbps due to potential compatibility issues. Also
ethtool doesn't support yet controlling EEE for 2.5Gbps and 5Gbps.

RTL8125 uses a different register number for IntrMask.
To net have side effects by reading a random register let's
use a register that is the same on all supported chip families.
