In nand_scan_ident(), the controller driver resets every NAND chip.
This is done by sending NAND_CMD_RESET. The Denali IP provides
another way to do the equivalent thing; if a bit is set in the
DEVICE_RESET register, the controller sends the RESET command to
the corresponding device. denali_reset_banks() uses it to reset
all devices beforehand.
This redundant reset sequence was needed to know the actual number
of chips before calling nand_scan_ident(); if DEVICE_RESET fails,
there is no chip in that chip select. Then, denali_reset_banks()
sets denali->max_banks to the number of detected chips.
As commit f486287d23 ("mtd: nand: denali: fix bank reset function
to detect the number of chips") explained, nand_scan_ident() issued
Set Features (0xEF) command to all CS lines, some of which may not be
connected with a chip. Then, the driver would wait for R/B# response,
which never happens.
This problem was solved by commit 107b7d6a7a ("mtd: rawnand: avoid
setting again the timings to mode 0 after a reset"). In the current
code, nand_setup_data_interface() is called from nand_scan_tail(),
which is invoked after the chip detection.
Now, we can really remove the redundant denali_nand_banks() by simply
passing the maximum number of chip selects supported by this IP
(typically 4 or 8) to nand_scan(). Let's leave all the chip detection
process to nand_scan_ident().

The Denali NAND IP has no way to read out the current signal level
of the R/B# pin. Instead, denali_dev_ready() checks if the R/B#
transition has already happened. (The INTR__INT_ACT interrupt is
asserted at the rising edge of the R/B# pin.) It is not a correct
way to implement the ->dev_ready() hook.
In fact, it has a drawback; in the nand_scan_ident phase, the chip
detection iterates over maxchips until it fails to find a homogeneous
chip. For the last loop, nand_reset() fails if no chip is there.
If ->dev_ready hook exists, nand_command(_lp) calls nand_wait_ready()
after NAND_CMD_RESET. However, we know denali_dev_ready() never
returns 1 unless there exists a chip that toggles R/B# in that chip
select. Then, nand_wait_ready() just ends up with wasting 400 msec,
in the end, shows the "timeout while waiting for chip to become ready"
warning.
Let's remove the mis-implemented dev_ready hook, and fallback to
sending the NAND_CMD_STATUS and nand_wait_status_ready(), which
bails out more quickly.

Data port used by the driver is actually an OMAP MPUIO device, already
under control of gpio-omap driver. For that reason we used to not
request the memory region of the port as that would fail because the
region is already busy. Despite that, we are still accessing the port
by just ioremapping it and performing read/write operations. Moreover,
we are doing that without any proteciton from other users legally
manipulating the port pins over GPIO API.
The plan is to convert the driver to access the port over GPIO consumer
API. Before that happens, already prevent from other users accessing
the port pins by requesting an array of its GPIO descriptors.

Pull x86 fixes from Thomas Gleixner:
"A set of x86 fixes:
- Cure the LDT remapping to user space on 5 level paging which ended
up in the KASLR space
- Remove LDT mapping before freeing the LDT pages
- Make NFIT MCE handling more robust
- Unbreak the VSMP build by removing the dependency on paravirt ops
- Support broken PIT emulation on Microsoft hyperV
- Don't trace vmware_sched_clock() to avoid tracer recursion
- Remove -pipe from KBUILD CFLAGS which breaks clang and is also
slower on GCC
- Trivial coding style and typo fixes"

Pull perf fixes from Thomas Gleixner:
"A bunch of perf tooling fixes:
- Make the Intel PT SQL viewer more robust
- Make the Intel PT debug log more useful
- Support weak groups in perf record so it's behaving the same way as
perf stat
- Display the LBR stats in callchain entries properly in perf top
- Handle different PMu names with common prefix properlin in pert
stat
- Start syscall augmenting in perf trace. Preparation for
architecture independent eBPF instrumentation of syscalls.
- Fix build breakage in JVMTI perf lib
- Fix arm64 tools build failure wrt smp_load_{acquire,release}"
