Although the datasheet states the CNVR flag is cleared by reading the BUS_VOLTAGE register, it is actually cleared by reading any of the voltage/current/power registers.

On some Meson8 devices the channel muxes are not programmed. This results in garbage values when trying to read channels that are not set up. Fix this by initializing the channel 0 and 1 muxes in MESON_SAR_ADC_CHAN_10_SW as well as the muxes for all other channels in MESON_SAR_ADC_AUX_SW based on what the vendor driver does (which is simply a 1:1 mapping of channel number and channel mux). This only showed up on Meson8 devices, because for GXBB and newer BL30 is taking care of initializing the channel muxes. This additionally fixes a typo in the MESON_SAR_ADC_AUX_SW_MUX_SEL_CHAN_MASK macro because the old definition assumed that the register fields were 2 bit wide, while they are actually 3 bit wide.

GX SoCs use a 1.2 MHz ADC clock, while the older SoCs use a 1.14 MHz clock. A comment in the driver from Amlogic's GPL kernel says that it's running at 1.28 MHz. However, it's actually programming a divider of 20 + 1. With a XTAL clock of 24 MHz this results in a frequency of 1.14 MHz. (their calculation might be based on a 27 MHz XTAL clock, but this is not what we have on the Meson8 and Meson8b SoCs). The ADC was still working with the 1.2MHz clock. In my own tests I did not see a difference between 1.2 and 1.14 MHz (regardless of the clock frequency used, the ADC results were identical).

Arnd Bergmann authored
getnstimeofday() suffers from the overflow in y2038 on 32-bit architectures and requires a conversion into the nanosecond format that we want here. This changes ssp_parse_dataframe() to use ktime_get_real_ns() directly, which does not have that problem. An open question is what time base should be used here. Normally timestamps should use ktime_get_ns() or ktime_get_boot_ns() to read monotonic time instead of "real" time, which suffers from time jumps due to settimeofday() calls or leap seconds.

Pull irq fixes from Thomas Gleixner: "A rather large update after the kaisered maintainer finally found time to handle regression reports. - The larger part addresses a regression caused by the x86 vector management rework. The reservation based model does not work reliably for MSI interrupts, if they cannot be masked (yes, yet another hw engineering trainwreck). The reason is that the reservation mode assigns a dummy vector when the interrupt is allocated and switches to a real vector when the interrupt is requested. If the MSI entry cannot be masked then the initialization might raise an interrupt before the interrupt is requested, which ends up as spurious interrupt and causes device malfunction and worse. The fix is to exclude MSI interrupts which do not support masking from reservation mode and assign a real vector right away. - Extend the extra lockdep class setup for nested interrupts with a class for the recently added irq_desc::request_mutex so lockdep can differeniate and does not emit false positive warnings. - A ratelimit guard for the bad irq printout so in case a bad irq comes back immediately the system does not drown in dmesg spam" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/msi, x86/vector: Prevent reservation mode for non maskable MSI genirq/irqdomain: Rename early argument of irq_domain_activate_irq() x86/vector: Use IRQD_CAN_RESERVE flag genirq: Introduce IRQD_CAN_RESERVE flag genirq/msi: Handle reactivation only on success gpio: brcmstb: Make really use of the new lockdep class genirq: Guard handle_bad_irq log messages kernel/irq: Extend lockdep class for request mutex

The error path in write_ldt() tries to free 'old_ldt' instead of the newly allocated 'new_ldt', resulting in a memory leak. It also misses to clean up a half populated LDT pagetable, which is not a leak as it gets cleaned up when the process exits. Free both the potentially half populated LDT pagetable and the newly allocated LDT struct. This can be done unconditionally because once an LDT is mapped subsequent maps will succeed, because the PTE page is already populated and the two LDTs fit into that single page.

The preempt_disable/enable() pair in __native_flush_tlb() was added in commit: 5cf0791d ("x86/mm: Disable preemption during CR3 read+write") ... to protect the UP variant of flush_tlb_mm_range(). That preempt_disable/enable() pair should have been added to the UP variant of flush_tlb_mm_range() instead. The UP variant was removed with commit: ce4a4e56 ("x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly) SMP code") ... but the preempt_disable/enable() pair stayed around. The latest change to __native_flush_tlb() in commit: 6fd166aa ("x86/mm: Use/Fix PCID to optimize user/kernel switches") ... added an access to a per CPU variable outside the preempt disabled regions, which makes no sense at all. __native_flush_tlb() must always be called with at least preemption disabled.

smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector() invoke local_flush_tlb() for no obvious reason. Digging in history revealed that the original code in the 2.1 era added those because the code manipulated a swapper_pg_dir pagetable entry. The pagetable manipulation was removed long ago in the 2.3 timeframe, but the TLB flush invocations stayed around forever.

It appears that hardened gentoo enables "-fstack-check" by default for gcc. That doesn't work _at_all_ for the kernel, because the kernel stack doesn't act like a user stack at all: it's much smaller, and it doesn't auto-expand on use. So the extra "probe one page below the stack" code generated by -fstack-check just breaks the kernel in horrible ways, causing infinite double faults etc. [ I have to say, that the particular code gcc generates looks very stupid even for user space where it works, but that's a separate issue. ] Reported-and-tested-by: Alexander Tsoy <alexander@tsoy.me> Reported-and-tested-by: Toralf Förster <toralf.foerster@gmx.de> Cc: stable@kernel.org Cc: Dave Hansen <dave.hansen@intel.com> Cc: Jiri Kosina <jikos@kernel.org> Cc: Andy Lutomirski <luto@amacapital.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
