Drop patch that was superseded upstream: ramips/0036-mtd-fix-cfi-cmdset-0002-erase-status-check.patch Drop upstreamed patches: - apm821xx/020-0001-crypto-crypto4xx-remove-bad-list_del.patch - apm821xx/020-0011-crypto-crypto4xx-fix-crypto4xx_build_pdr-crypto4xx_b.patch - ath79/0011-MIPS-ath79-fix-register-address-in-ath79_ddr_wb_flus.patch - brcm63xx/001-4.15-08-bcm63xx_enet-correct-clock-usage.patch - brcm63xx/001-4.15-09-bcm63xx_enet-do-not-write-to-random-DMA-channel-on-B.patch - generic/backport/080-net-convert-sock.sk_wmem_alloc-from-atomic_t-to-refc.patch - generic/pending/170-usb-dwc2-Fix-DMA-alignment-to-start-at-allocated-boun.patch - generic/pending/900-gen_stats-fix-netlink-stats-padding.patch In 4.14.55, a patch was introduced that breaks ext4 images in some cases. The newly introduced patch backport-4.14/500-ext4-fix-check-to-prevent-initializing-reserved-inod.patch addresses this breakage. Fixes the following CVEs: - CVE-2018-10876 - CVE-2018-10877 - CVE-2018-10879 - CVE-2018-10880 - CVE-2018-10881 - CVE-2018-10882 - CVE-2018-10883 Compile-tested: ath79, octeon, x86/64 Runtime-tested: ath79, octeon, x86/64 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
