Since RPMB area is accessible via special ioctl only and boot areas
are unlikely to contain any partitions, exclude them all from listing
in /proc/partitions. This will hide them from various user-level
software (e.g. fdisk), thus avoiding unnecessary access attempts.

Add support for the JZ4780 MMC controller to the jz47xx_mmc driver. There
are a few minor differences from the 4740 to the 4780 that need to be
handled, but otherwise the controllers behave the same. The IREG and IMASK
registers are expanded to 32 bits. Additionally, some error conditions are
now reported in both STATUS and IREG. Writing IREG before reading STATUS
causes the bits in STATUS to be cleared, so STATUS must be read first to
ensure we see and report error conditions correctly.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
(kernel Oops) or a security flaw (overwriting memory beyond the
stack). Also, in general, as code evolves it is easy to lose track of
how big a VLA can get. Thus, we can end up having runtime failures
that are hard to debug. As part of the directive[1] to remove all VLAs
from the kernel, and build with -Wvla.
Currently driver is using a VLA declared using the number of descriptors. This
array is used to store integer values and is later used as an argument to
`gpiod_set_array_value_cansleep()` This can be avoided by using
`kmalloc_array()` to allocate memory for the array of integer values. Memory is
free'd before return from function.
>From the code it appears that it is safe to sleep so we can use GFP_KERNEL
(based _cansleep() suffix of function `gpiod_set_array_value_cansleep()`.
It can be expected that this patch will result in a small increase in overhead
due to the use of `kmalloc_array()`

On SD 2.00 cards we get lots of these messages:
"mmc0: Got data interrupt 0x00000002 even though no data operation was in progress"
By applying the SDHCI_QUIRK2_STOP_WITH_TC quirk, the messages no longer happen.
A single card claiming to be SD 3.00 compliant also generates the interrupts,
but since the card's manfacturing date is 2002 mar, it's unlikely to really be
SD 3.00. This card is a 8GB SanDisk 'SU08G' 8.0 (SDHC class 4).
This has been reported on Xilinx devices that also use the Arasan IP.
See https://patchwork.kernel.org/patch/8062871/
This has been tested on the Renesas RZ/ND-DB board with the RZ/N1 SoC. The

"Another set of x86 related updates:
- Fix the long broken x32 version of the IPC user space headers which
was noticed by Arnd Bergman in course of his ongoing y2038 work.
GLIBC seems to have non broken private copies of these headers so
this went unnoticed.
- Two microcode fixlets which address some more fallout from the
recent modifications in that area:
- Unconditionally save the microcode patch, which was only saved
when CPU_HOTPLUG was enabled causing failures in the late
loading mechanism
- Make the later loader synchronization finally work under all
circumstances. It was exiting early and causing timeout failures
due to a missing synchronization point.
- Do not use mwait_play_dead() on AMD systems to prevent excessive
power consumption as the CPU cannot go into deep power states from
there.
- Address an annoying sparse warning due to lost type qualifiers of
the vmemmap and vmalloc base address constants.
- Prevent reserving crash kernel region on Xen PV as this leads to
the wrong perception that crash kernels actually work there which
is not the case. Xen PV has its own crash mechanism handled by the
hypervisor.
- Add missing TLB cpuid values to the table to make the printout on
certain machines correct.

ext4: fix bitmap position validation

ext4: prevent right-shifting extents beyond EXT_MAX_BLOCKS
The comment claims that this helper will try not to loose bits, but for
64bit long it looses the high bits before hashing 64bit long into 32bit
int. Use the helper hash_long() to do the right thing for 64bit long.
For 32bit long, there is no change.
All the callers of end_name_hash() either assign the result to
qstr->hash, which is u32 or return the result as an int value (e.g.
full_name_hash()). Change the helper return type to int to conform to
its users.
[ It took me a while to apply this, because my initial reaction to it
was - incorrectly - that it could make for slower code.
After having looked more at it, I take back all my complaints about
the patch, Amir was right and I was mis-reading things or just being
stupid.
I also don't worry too much about the possible performance impact of
this on 64-bit, since most architectures that actually care about
performance end up not using this very much (the dcache code is the
most performance-critical, but the word-at-a-time case uses its own
hashing anyway).
So this ends up being mostly used for filesystems that do their own
degraded hashing (usually because they want a case-insensitive
comparison function).
A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
and then this potentially makes things more expensive on 64-bit
architectures with slow or lacking multipliers even for the normal
case.
That said, realistically the only such architecture I can think of is
PA-RISC. Nobody really cares about performance on that, it's more of a
"look ma, I've got warts^W an odd machine" platform.
So the patch is fine, and all my initial worries were just misplaced
from not looking at this properly. - Linus ]

Here are some small char and misc driver fixes for 4.17-rc3
A variety of small things that have fallen out after 4.17-rc1 was out.
Some vboxguest fixes for systems with lots of memory, amba bus fixes,
some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other
minor things that resolve problems that people reported.
The amba bus fixes took twice to get right, the first time I messed up
applying the patches in the wrong order, hence the revert and later
addition again with the correct fix, sorry about that.
All of these have been in linux-next with no reported issues.

This round of fixes has two larger changes that came in last week:
- A set of a couple of patches all intended to finally turn on
USB support on various Amlogic SoC based boards. The respective
driver were not finalized until very late before the merge window
and the DT portion is the last bit now.
- A defconfig update for gemini that had repeatedly missed the
cut but that is required to actually boot any real machines
with the default build.
The rest are the usual small changes:
- A fix for a nasty build regression on the OMAP memory drivers
- A fix for a boot problem on Intel/Altera SocFPGA
- A MAINTAINER file update
- A couple of fixes for issues found by automated testing
(kernelci, coverity, sparse, ...)
- A few incorrect DT entries are updated to match the hardware

Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Arnd Bergmann:
"This round of fixes has two larger changes that came in last week:
- a couple of patches all intended to finally turn on USB support on
various Amlogic SoC based boards. The respective driver were not
finalized until very late before the merge window and the DT
portion is the last bit now.
- a defconfig update for gemini that had repeatedly missed the cut
but that is required to actually boot any real machines with the
default build.
The rest are the usual small changes:
- a fix for a nasty build regression on the OMAP memory drivers
- a fix for a boot problem on Intel/Altera SocFPGA
- a MAINTAINER file update
- a couple of fixes for issues found by automated testing (kernelci,
coverity, sparse, ...)
- a few incorrect DT entries are updated to match the hardware"

Currently, KVM flushes the TLB after a change to the APIC access page
address or the APIC mode when EPT mode is enabled. However, even in
shadow paging mode, a TLB flush is needed if VPIDs are being used, as
specified in the Intel SDM Section 29.4.5.
So replace vmx_flush_tlb_ept_only() with vmx_flush_tlb(), which will
flush if either EPT or VPIDs are in use.

32-bit user code that uses int $80 doesn't care about r8-r11. There is,
however, some 64-bit user code that intentionally uses int $0x80 to invoke
32-bit system calls. From what I've seen, basically all such code assumes
that r8-r15 are all preserved, but the kernel clobbers r8-r11. Since I
doubt that there's any code that depends on int $0x80 zeroing r8-r11,
change the kernel to preserve them.
I suspect that very little user code is broken by the old clobber, since
r8-r11 are only rarely allocated by gcc, and they're clobbered by function
calls, so they only way we'd see a problem is if the same function that
invokes int $0x80 also spills something important to one of these
registers.
The current behavior seems to date back to the historical commit
"[PATCH] x86-64 merge for 2.6.4". Before that, all regs were
preserved. I can't find any explanation of why this change was made.
Update the test_syscall_vdso_32 testcase as well to verify the new
behavior, and it strengthens the test to make sure that the kernel doesn't
accidentally permute r8..r15.

A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout
(as seen from user space) a few years ago: Originally, __BITS_PER_LONG
was defined as 64 on x32, so we did not have padding after the 64-bit
__kernel_time_t fields, After __BITS_PER_LONG got changed to 32,
applications would observe extra padding.
In other parts of the uapi headers we seem to have a mix of those
expecting either 32 or 64 on x32 applications, so we can't easily revert
the path that broke these two structures.
Instead, this patch decouples x32 from the other architectures and moves
it back into arch specific headers, partially reverting the even older
commit 73a2d096fd ("x86: remove all now-duplicate header files").
It's not clear whether this ever made any difference, since at least
glibc carries its own (correct) copy of both of these header files,
so possibly no application has ever observed the definitions here.
Based on a suggestion from H.J. Lu, I tried out the tool from
https://github.com/hjl-tools/linux-header to find other such
bugs, which pointed out the same bug in statfs(), which also has
a separate (correct) copy in glibc.

Xen PV domains cannot shut down and start a crash kernel. Instead,
the crashing kernel makes a SCHEDOP_shutdown hypercall with the
reason code SHUTDOWN_crash, cf. xen_crash_shutdown() machine op in
arch/x86/xen/enlighten_pv.c.
A crash kernel reservation is merely a waste of RAM in this case. It
may also confuse users of kexec_load(2) and/or kexec_file_load(2).
When flags include KEXEC_ON_CRASH or KEXEC_FILE_ON_CRASH,
respectively, these syscalls return success, which is technically
correct, but the crash kexec image will never be actually used.

i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which
returns ZERO_SIZE_PTR if i2c_msg.len is zero.
Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case
of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in
case of zero len.
Let's check the len against zero before dereferencing buf pointer.
