clocksource: Allow clocksource_mark_unstable() on unregistered clocksources
Because of how the code flips between tsc-early and tsc clocksources
it might need to mark one or both unstable. The current code in
mark_tsc_unstable() only worked because previously it registered the
tsc clocksource once and then never touched it.
Since it now unregisters the tsc-early clocksource, it needs to know
if a clocksource got unregistered and the current cs->mult test
doesn't work for that. Instead use list_empty(&cs->list) to test for
registration.
Furthermore, since clocksource_mark_unstable() needs to place the cs
on the wd_list, it links the cs->list and cs->wd_list serialization.
It must not see a clocsource registered (!empty cs->list) but already
past dequeue_watchdog(). So place {en,de}queue{,_watchdog}() under the
same lock.
Provided cs->list is initialized to empty, this then allows us to
unconditionally use clocksource_mark_unstable(), regardless of the
registration state.

x86/tsc: Always unregister clocksource_tsc_early
Don't leave the tsc-early clocksource registered if it errors out
early.
This was reported by Diego, who on his Core2 era machine got TSC
invalidated while it was running with tsc-early (due to C-states).
This results in keeping tsc-early with very bad effects.

"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.
- Enumerate the new CLDEMOTE instruction
- Fix an incorrect SPDX identifier
- Remove stale macros"

<linux/stringhash.h>: fix end_name_hash() for 64bit long
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 ] Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

powerpc fixes for 4.17 #4
A bunch of fixes, mostly for existing code and going to stable. Our memory hot-unplug path wasn't flushing the cache before removing memory. That is a problem now that we are doing memory hotplug on bare metal. Three fixes for the NPU code that supports devices connected via NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to avoid soft lockups for large flushes. A fix for our memory error handling where we would loop infinitely, returning back to the bad access and hard lockup the CPU. Fixes for the OPAL RTC driver, which wasn't handling some error cases correctly. A fix for a hardlockup in the powernv cpufreq driver. And finally two fixes to our smp_send_stop(), required due to a recent change to use it on shutdown.

Char/Misc driver fixes for 4.17-rc3
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.

USB fixes for 4.17-rc3
Here are a number of USB driver fixes for reported problems for
4.17-rc3.
The "largest" here is a number of phy core changes for reported problems
with the -rc1 release. There's also the usual musb and xhci fixes, as
well as new device id updates. There are also some usbip fixes for
reported problems as more people start to use that code with containers.
All of these have been in linux-next with no reported issues, except the
last few new device ids, which are "obviously correct" :)

ARM: SoC fixes for 4.17
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

kvm: apic: Flush TLB after APIC mode/address change if VPIDs are in use
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.

x86/entry/64/compat: Preserve r8-r11 in int $0x80
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.

x86/ipc: Fix x32 version of shmid64_ds and msqid64_ds
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 |

x86/setup: Do not reserve a crash kernel region if booted on Xen PV
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.

i2c: dev: prevent ZERO_SIZE_PTR deref in i2cdev_ioctl_rdwr()
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. This issue was triggered by syzkaller.

arm64: avoid instrumenting atomic_ll_sc.o
Our out-of-line atomics are built with a special calling convention, preventing pointless stack spilling, and allowing us to patch call sites with ARMv8.1 atomic instructions. Instrumentation inserted by the compiler may result in calls to functions not following this special calling convention, resulting in registers being unexpectedly clobbered, and various problems resulting from this. For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of the atomic functions. This has been observed to result in spurious cmpxchg failures, leading to a hang early on in the boot process. This patch avoids such issues by preventing instrumentation of our out-of-line atomics.

One way to avoid this is removing the smp-call. We can ensure that the
timer always runs on one of the policy-cpus. If the timer gets
migrated to a cpu outside the policy then re-queue it back on the
policy->cpus. This way we can get rid of the smp-call which was being
used to set the pstate on the policy->cpus.

ACPI fixes for 4.17-rc3
- Change the ACPI subsystem initialization ordering to initialize
the WDAT watchodg before reserving PNP motherboard resources so
as to allow the watchdog to allocate its resources before the PNP
code gets to them and prevents it from working correctly (Mika
Westerberg).
- Add a quirk for Lenovo Z50-70 to use the iTCO watchdog instead of
the WDAT one which conflicts with the RTC on that platform (Mika
Westerberg).
- Avoid breaking backlight handling on Dell XPS 13 2013 model by
allowing laptops to use the ACPI backlight by default even if they
are Windows 8-ready in principle (Hans de Goede).

Merge tag 'acpi-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These are two watchdog-related fixes, fix for a backlight regression
from the 4.16 cycle that unfortunately was propagated to -stable and a
button module modification to prevent graphics driver modules from
failing to load due to unmet dependencies if ACPI is disabled from the
kernel command line.
Specifics:
- Change the ACPI subsystem initialization ordering to initialize the
WDAT watchodg before reserving PNP motherboard resources so as to
allow the watchdog to allocate its resources before the PNP code
gets to them and prevents it from working correctly (Mika
Westerberg).
- Add a quirk for Lenovo Z50-70 to use the iTCO watchdog instead of

Westerberg).

Power management fixes for 4.17-rc3
- Blacklist the Low Power S0 Idle _DSM on ThinkPad X1 Tablet(2016)
where it causes issues and make it use ACPI S3 which works instead
of the non-working suspend-to-idle by default (Chen Yu).
- Fix the handling of hibernation in the PCI core for devices with
the DPM_FLAG_SMART_SUSPEND flag set to fix a regression affecting
intel-lpss I2C devices (Mika Westerberg).
- Drop development debug code from the brcmstb-avs-cpufreq driver
(Markus Mayer).
