* kernel: drop MIPS fix cache flushing for highmem pagesKevin Darbyshire-Bryant2018-12-20
| | | | | | | | | | | | | | | | | | | | | This patch, in a variety of forms, has been around since beginning 2016 as e756c2bb07, ending up in present form 0aa6c7df60 (kernel 4.4.13 bump) and carried forward ever since. There have been a number of MIPS kernel memory handling changes since, including VDSO fixes that meant openwrt patches have been dropped with no apparent fallout. Simple tests (ntfs-3g) on a HIGHMEM 512MB mt7621 device have not turned up data corruption issues which would otherwise be expected. Similarly running on other MIPS based devices for the past 2 months hasn't turned up anything obvious to retain this out of tree patch. With thanks to Rosen Penev for testing on the known 'highmem' device and Felix Fietkau for testing advice. Not putting acked-by as it's my fault if it breaks :-) Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* jffs2: Fix use of uninitialized delayed_work, lockdep breakageDaniel Santos2018-12-16
| | | | | | | | | | I've sent this one upstream. This patch is critical if you want to run with "prove lock correctness" (lockdep) and you happen to have certain mtd devices. The misuse of the uninitialized object is undefined behaviour, but being zeroed it does not appear to have actually broken anything other than the lockdep engine.

* kernel: Make the patches apply on top of 4.19Hauke Mehrtens2018-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the patches which were just copied in the previous commit apply on top of kernel 4.19. The patches in the backports-4.19 folder were checked if they are really in kernel 4.19 based on the title and only removed if they were found in the upstream kernel. The following additional patches form the pending folder went into upstream Linux 4.19: pending-4.19/171-usb-dwc2-Fix-inefficient-copy-of-unaligned-buffers.patch pending-4.19/190-2-5-e1000e-Fix-wrong-comment-related-to-link-detection.patch pending-4.19/478-mtd-spi-nor-Add-support-for-XM25QH64A-and-XM25QH128A.patch pending-4.19/479-mtd-spi-nor-add-eon-en25qh32.patch pending-4.19/950-tty-serial-exar-generalize-rs485-setup.patch pending-4.19/340-MIPS-mm-remove-mips_dma_mapping_error.patch Bigger changes were introduced to the m25p80 spi nor driver, as far as I saw it in the new code, it now has the functionality provided in this patch: pending-4.19/450-mtd-m25p80-allow-fallback-from-spi_flash_read-to-reg.patch Part of this patch went upstream independent of OpenWrt: hack-4.19/220-gc_sections.patch This patch was reworked to match the changes done upstream. The MIPS DMA API changed a lot, this patch was rewritten to match the new DMA handling: pending-4.19/341-MIPS-mm-remove-no-op-dma_map_ops-where-possible.patch I did bigger manual changes to the following patches and I am not 100% sure if they are all correct: pending-4.19/0931-w1-gpio-fix-problem-with-platfom-data-in-w1-gpio.patch pending-4.19/411-mtd-partial_eraseblock_write.patch pending-4.19/600-netfilter_conntrack_flush.patch pending-4.19/611-netfilter_match_bypass_default_table.patch pending-4.19/670-ipv6-allow-rejecting-with-source-address-failed-policy.patch hack-4.19/211-host_tools_portability.patch hack-4.19/221-module_exports.patch hack-4.19/321-powerpc_crtsavres_prereq.patch hack-4.19/902-debloat_proc.patch This is based on patchset from Marko Ratkaj <marko.ratkaj@sartura.hr> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Copy patches from kernel 4.14 to 4.19Hauke Mehrtens2018-12-15
This just copies the files from the kernel 4.14 specific folders into the kernel 4.19 specific folder, no changes are done to the files in this commit. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
