PD#158752: lcd: optimize gpio register function for init value
For gpio register required init value, we can't register gpio when

by bootloader init.
So we register gpio when first calling by lcd power step controlling.

PD#159028: char_dev: extend dynamic allocation of majors into a higher range
We've run into problems with running out of dynamicly assign char
device majors particullarly on automated test systems with
all-yes-configs. Roughly 40 dynamic assignments can be made with such
kernels at this time while space is reserved for only 20.
Currently, the kernel only prints a warning when dynamic allocation
overflows the reserved region. And when this happens drivers that have
fixed assignments can randomly fail depending on the order of
initialization of other drivers. Thus, adding a new char device can cause
unexpected failures in completely unrelated parts of the kernel.
This patch solves the problem by extending dynamic major number
allocations down from 511 once the 234-254 region fills up. Fixed
majors already exist above 255 so the infrastructure to support
high number majors is already in place. The patch reserves an
additional 128 major numbers which should hopefully last us a while.
Kernels that don't require more than 20 dynamic majors assigned (which
is pretty typical) should not be affected by this change.

PD#158373: mm: check pfn overflow for low memory platform
On ARM64 platform, when vmemmap_populate is called for reserve
memory for struct page, it reserved based 1GB a loop. And 16MB
memory will be reserved at least. This caused memory waste if
total RAM is less than 1GB.
Basically reserve memory size for struct page is calculated by:
reserve size = sizeof(struct page) * number of pages.
For example, currently struct page is 64 bytes on ARM64. A page
is 4KB. So reserve size table can be:
Memory | page count | reserve size(bytes)
-------------------------------------------------
128MB | 32768 | 2097152(2MB)
256MB | 65536 | 4194304(4MB)
512MB | 131072 | 8388608(8MB)
Note, This reserve is aligned at 2MB.

commit fee4380f36 upstream.
In the current driver, OOB bytes are accessed in raw mode, and when a
page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the
driver must read the whole spare area (64 bytes in case of a 2k page,
16 bytes for a 512 page). The driver was only reading the free OOB
bytes, which was leaving some unread data in the FIFO and was somehow
leading to a timeout.
We could patch the driver to read ->spare_size + ->ecc_size instead of
just ->spare_size when READOOB is requested, but we'd better make
in-band and OOB accesses consistent.
Since the driver is always accessing in-band data in non-raw mode (with
the ECC engine enabled), we should also access OOB data in this mode.
That's particularly useful when using the BCH engine because in this
mode the free OOB bytes are also ECC protected.
Fixes: 43bcfd2bb2 ("mtd: nand: pxa3xx: Add driver-specific ECC BCH support")

This needs to happen early in kaiser_pagetable_walk(), before the
hierarchy is established so that _PAGE_USER permission can be really
set.
A proper fix would be to teach kaiser_pagetable_walk() to update those

commit 1e5476815f upstream.
The recent changes for PTI touch cpu_tlbstate from various tlb_flush
inlines. cpu_tlbstate is exported as GPL symbol, so this causes a
regression when building out of tree drivers for certain graphics cards.
Aside of that the export was wrong since it was introduced as it should
have been EXPORT_PER_CPU_SYMBOL_GPL().
Use the correct PER_CPU export and drop the _GPL to restore the previous
state which allows users to utilize the cards they payed for.
As always I'm really thrilled to make this kind of change to support the
#friends (or however the hot hashtag of today is spelled) from that closet
sauce graphics corp.

commit 88776c0e70 upstream.
Qemu for PARISC reported on a 32bit SMP parisc kernel strange failures
about "Not-handled unaligned insn 0x0e8011d6 and 0x0c2011c9."
Those opcodes evaluate to the ldcw() assembly instruction which requires
(on 32bit) an alignment of 16 bytes to ensure atomicity.
As it turns out, qemu is correct and in our assembly code in entry.S and
pacache.S we don't pay attention to the required alignment.
This patch fixes the problem by aligning the lock offset in assembly
code in the same manner as we do in our C-code.
