2020-07-20ARM: dts: at91: sama5d3_xplained: change phy-modeAlexandre Belloni1-1/+1
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY"), networking is broken on sama5d3 xplained. The device tree has phy-mode = "rgmii" and this worked before, because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the KSZ9031 PHY starts handling phy mode properly and disables RX delay, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.

2020-07-20s390/kernel: expand exception table logic to allow new handling optionsIlya Leoshkevich5-17/+53
This is a s390 port of commit 548acf19234d ("x86/mm: Expand the exception table logic to allow new handling options"), which is needed for implementing BPF_PROBE_MEM on s390. The new handler field is made 64-bit in order to allow pointing from dynamically allocated entries to handlers in kernel text. Unlike on x86, NULL is used instead of ex_handler_default. This is because exception tables are used by boot/text_dma.S, and it would be a pain to preserve ex_handler_default. The new infrastructure is ignored in early_pgm_check_handler, since there is no pt_regs.

2020-07-20s390/mm: allow order 10 allocationsHeiko Carstens1-4/+0
Get rid of FORCE_MAX_ZONEORDER which limited allocations to order 8 (= 1MB) and use the default, which allows for order 10 (= 4MB) allocations. Given that s390 allows less than the default this caused some memory allocation problems more or less unique to s390 from time to time. Note: this was originally introduced with commit 684de39bd795 ("[S390] Fix IPL from NSS.") in order to support Named Saved Segments, which could start/end at an arbitrary 1 megabyte boundary and also before support for sparsemem vmemmmap was enabled. Since NSS support is gone, but sparsemem vmemmap support is available this limitation can go away. Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
2020-07-20s390/mm: avoid trimming to MAX_ORDERHeiko Carstens1-8/+0
Trimming to MAX_ORDER was originally done in order to avoid to set HOLES_IN_ZONE, which in turn would enable a quite expensive pfn_valid() check. pfn_valid() however only checks if a struct page exists for a given pfn. With sparsemen vmemmap there are always struct pages, since memmaps are allocated for whole sections. Therefore remove the HOLES_IN_ZONE comment and the trimming.

2020-07-20ARM: dts: exynos: Disable frequency scaling for FSYS bus on Odroid XU3 familyMarek Szyprowski1-6/+0
Commit 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the values correct for Exynos5422 Odroids") changed the parameters of the OPPs for the FSYS bus. Besides the frequency adjustments, it also removed the 'shared-opp' property from the OPP table used for FSYS_APB and FSYS busses. This revealed that in fact the FSYS bus frequency scaling never worked. When one OPP table is marked as 'opp-shared', only the first bus which selects the OPP sets the rate of its clock. Then OPP core assumes that the other busses have been changed to that OPP and no change to their clock rates are needed. Thus when FSYS_APB bus, which was registered first, set the rate for its clock, the OPP core did not change the FSYS bus clock later. The mentioned commit removed that behavior, what introduced a regression on some Odroid XU3 boards. Frequency scaling of the FSYS bus causes instability of the USB host operation, what can be observed as network hangs. To restore old behavior, simply disable frequency scaling for the FSYS bus.

Pull irq fixes from Thomas Gleixner: "Two fixes for the interrupt subsystem: - Make the handling of the firmware node consistent and do not free the node after the domain has been created successfully. The core code stores a pointer to it which can lead to a use after free or double free. This used to "work" because the pointer was not stored when the initial code was written, but at some point later it was required to store it. Of course nobody noticed that the existing users break that way. - Handle affinity setting on inactive interrupts correctly when hierarchical irq domains are enabled. When interrupts are inactive with the modern hierarchical irqdomain design, the interrupt chips are not necessarily in a state where affinity changes can be handled. The legacy irq chip design allowed this because interrupts are immediately fully initialized at allocation time. X86 has a hacky workaround for this, but other implementations do not. This cased malfunction on GIC-V3. Instead of playing whack a mole to find all affected drivers, change the core code to store the requested affinity setting and then establish it when the interrupt is allocated, which makes the X86 hack go away" * tag 'irq-urgent-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/affinity: Handle affinity setting on inactive interrupts correctly irqdomain/treewide: Keep firmware node unconditionally allocated

2020-07-18ARM: dts: dlink-dns327l: fix reg-init PHYDaniel González Cabanelas1-3/+2
The marvell PHY reg-init registers for the D-Link DNS-327L are wrong. Currently the first field is used to set the page 2, but this is pointless. The usage is not correct, and we are setting the wrong registers. Fix it.

2020-07-18ARM: dts: kirkwood: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
