Memory mappings inside kernel allocated with vmalloc() are in
predictable order and packed tightly toward the low addresses. With
new kernel boot parameter 'randomize_vmalloc=1', the entire area is
used randomly to make the allocations less predictable and harder to
guess for attackers.

With Clang's Link Time Optimization (LTO), the compiler can rename
static functions to avoid global naming collisions. As PCI fixup

In preparation for removing logbuf_lock, inline log_output()
and log_store() into vprintk_store(). This will simplify dealing
with the various code branches and fallbacks that are possible.

Since the ringbuffer is lockless, there is no need for it to be
protected by @logbuf_lock. Remove @logbuf_lock.
This means that printk_nmi_direct and printk_safe_flush_on_panic()
no longer need to acquire any lock to run.
The global variables @syslog_seq, @syslog_partial, @syslog_time
were also
Currently @clear_seq access is protected by @logbuf_lock. Once
@logbuf_lock is removed some other form of synchronization will be
required. Change the type of @clear_seq to atomic64_t to provide the
synchronization.

This series falls in line with the printk-rework plan as
presented [1] at Linux Plumbers in Lisbon 2019.
The series is based on next-20201201.

Why do you need this when no other board does? Why is your board
special?
As i said before, i'm guessing your board has back to back

Add two sysfs nodes to the Intel MAX10 BMC driver: mac_address
and mac_count. The mac_address provides the first of a series
of sequential MAC addresses assigned to the FPGA card. The
mac_count indicates how many MAC addresses are assigned to the
card.
