Updating the hysteresis value when updating the critical temperature limit
was following the rule of 'least surprise'. However, it had the undesirable
side effect of changing the hysteresis for all other attributes, which
defeats the purpose of least surprise. In addition, it could result in
invalid hysteresis values if the resulting hysteresis was too large. In such
cases the resulting hysteresis ended up changed anyway, which again defeats
the purpose. So drop that code and document the new behavior.

This defconfig contains the CONFIG_M25P80 symbol, which is now

This series reworks VE's platform configuration infrastructure by:
- making it possible to instantiate selected devices from the
Device Tree, prior to massive population,
- converting custom "func" API into standard "regmap",
- splitting the existing MFD driver into smaller ones and placing
them into relevant directories.
The common clock framework driver can now be selected individually
(mostly for arm64 sake, where some of them are not used at all).
It also simplifies the machine code, by:
- moving the shed clock info clocksource driver,
- simplifying SMP operations to base them entirely of the DT data,
- moving platform ID checks into relevant driver.

When GRE support was added in linux-3.14, CHECKSUM_COMPLETE handling
broke on GRE+IPv6 because we did not update/use the appropriate csum :
GRO layer is supposed to use/update NAPI_GRO_CB(skb)->csum instead of
skb->csum
Tested using a GRE tunnel and IPv6 traffic. GRO aggregation now happens
at the first level (ethernet device) instead of being done in gre
tunnel. Native IPv6+TCP is still properly aggregated.

Kernel API for classic BPF socket filters is:
sk_unattached_filter_create() - validate classic BPF, convert, JIT
SK_RUN_FILTER() - run it
sk_unattached_filter_destroy() - destroy socket filter
Cleanup internal BPF kernel API as following:
sk_filter_select_runtime() - final step of internal BPF creation.
Try to JIT internal BPF program, if JIT is not available select interpreter
SK_RUN_FILTER() - run it
sk_filter_free() - free internal BPF program
Disallow direct calls to BPF interpreter. Execution of the BPF program should
be done with SK_RUN_FILTER() macro.
Example of internal BPF create, run, destroy:
struct sk_filter *fp;
fp = kzalloc(sk_filter_size(prog_len), GFP_KERNEL);
memcpy(fp->insni, prog, prog_len * sizeof(fp->insni[0]));
fp->len = prog_len;
sk_filter_select_runtime(fp);
SK_RUN_FILTER(fp, ctx);
sk_filter_free(fp);
Sockets, seccomp, testsuite, tracing are using different ways to populate
sk_filter, so first steps of program creation are not common.

* do vnic_intr_coalescing_timer_set only while enabling intr
* use ktime_get instead of hrtimer
* make enic_set_rx_coal_setting return type void
* change func name enic_apply_int_moderation to enic_calc_int_moderation

This patch adds support for adaptive interrupt coalescing.
For small pkts with low pkt rate, we can decrease the coalescing interrupt
dynamically which decreases the latency. This however increases the cpu
utilization. Based on testing with different coal intr and pkt rate we came up
with a table(mod_table) with rx_rate and coalescing interrupt value where we
get low latency without significant increase in cpu. mod_table table stores
the coalescing timer percentage value for different throughputs.
Function enic_calc_int_moderation() calculates the desired coalescing intr timer
value. This function is called in driver rx napi_poll. The actual value is set
by enic_set_int_moderation() which is called when napi_poll is complete. i.e
when we unmask the rx intr.
Adaptive coal intr is support only when driver is using msix intr. Because
intr is not shared.
Struct mod_range is used to store only the default adaptive coalescing intr
value.
Adaptive coal intr calue is calculated by
timer = range_start + ((rx_coal->range_end - range_start) *
mod_table[index].range_percent / 100);
rx_coal->range_end is the rx-usecs-high value set using ethtool.
range_start is rx-usecs-low, set using ethtool, if rx_small_pkt_bytes_cnt is
greater than 2 * rx_large_pkt_bytes_cnt. i.e small pkts are dominant. Else its
rx-usecs-low + 3.

"Here are a couple of fixes for 3.15. One from Anton fixes a nasty
regression I introduced when trying to fix a loss of irq_work whose
consequences is that we can completely lose timer interrupts on a
CPU... not pretty.
The other one is a change to our PCIe reset hook to use a firmware
call instead of direct config space accesses to trigger a fundamental
reset on the root port. This is necessary so that the FW gets a
chance to disable the link down error monitoring, which would
otherwise trip and cause subsequent fatal EEH error"

Prior to commit 0e4f6a791b (Fix reiserfs_file_release()), reiserfs
truncates serialized on i_mutex. They mostly still do, with the exception
of reiserfs_file_release. That blocks out other writers via the tailpack
mutex and the inode openers counter adjusted in reiserfs_file_open.
However, NFS will call reiserfs_setattr without having called ->open, so
we end up with a race when nfs is calling ->setattr while another
process is releasing the file. Ultimately, it triggers the
BUG_ON(inode->i_size != new_file_size) check in maybe_indirect_to_direct.
The solution is to pull the lock into reiserfs_setattr to encompass the
truncate_setsize call as well.

exposed by a device, we can end up in a situation where some of
the hardware queues are unused (as in, they don't map to any
