From: Hauke Mehrtens Date: Thu, 1 Nov 2018 17:01:44 +0000 (+0100) Subject: kernel: Make the patches apply on top of 4.19 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9261e7447ea7b8d33b70ff6ea008f2041a88e255;p=openwrt%2Fstaging%2Faparcar.git kernel: Make the patches apply on top of 4.19 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 Signed-off-by: Hauke Mehrtens --- diff --git a/include/kernel-version.mk b/include/kernel-version.mk index 7433b31078..dda480613c 100644 --- a/include/kernel-version.mk +++ b/include/kernel-version.mk @@ -5,10 +5,12 @@ LINUX_RELEASE?=1 LINUX_VERSION-3.18 = .129 LINUX_VERSION-4.9 = .145 LINUX_VERSION-4.14 = .88 +LINUX_VERSION-4.19 = .9 LINUX_KERNEL_HASH-3.18.129 = 8d420b58593a74109175be781da2320a341baec9aaa186da31ad508d3f377e72 LINUX_KERNEL_HASH-4.9.145 = 6901ca37e8c305a2f26c598952338b4dc2481ca5a9d0bf71e2b71730a5b5bc5e LINUX_KERNEL_HASH-4.14.88 = b0f0b8c76708eab6caf3009702e531d40a243b152922ee1f9a441316f226f52d +LINUX_KERNEL_HASH-4.19.9 = fc116cc6829c73944215d3b3ac0fc368dde9e8235b456744afffde001269dbf2 remove_uri_prefix=$(subst git://,,$(subst http://,,$(subst https://,,$(1)))) sanitize_uri=$(call qstrip,$(subst @,_,$(subst :,_,$(subst .,_,$(subst -,_,$(subst /,_,$(1))))))) diff --git a/target/linux/generic/backport-4.19/011-kbuild-export-SUBARCH.patch b/target/linux/generic/backport-4.19/011-kbuild-export-SUBARCH.patch index 3df01c34b1..b5f654906a 100644 --- a/target/linux/generic/backport-4.19/011-kbuild-export-SUBARCH.patch +++ b/target/linux/generic/backport-4.19/011-kbuild-export-SUBARCH.patch @@ -10,14 +10,14 @@ Signed-off-by: Felix Fietkau --- a/Makefile +++ b/Makefile -@@ -428,8 +428,8 @@ KBUILD_CFLAGS_MODULE := -DMODULE - KBUILD_LDFLAGS_MODULE := -T $(srctree)/scripts/module-common.lds +@@ -431,8 +431,8 @@ KBUILD_LDFLAGS_MODULE := -T $(srctree)/s + KBUILD_LDFLAGS := GCC_PLUGINS_CFLAGS := --export ARCH SRCARCH CONFIG_SHELL HOSTCC HOSTCFLAGS CROSS_COMPILE AS LD CC --export CPP AR NM STRIP OBJCOPY OBJDUMP HOSTLDFLAGS HOST_LOADLIBES -+export ARCH SRCARCH SUBARCH CONFIG_SHELL HOSTCC HOSTCFLAGS CROSS_COMPILE AS LD -+export CC CPP AR NM STRIP OBJCOPY OBJDUMP HOSTLDFLAGS HOST_LOADLIBES - export MAKE AWK GENKSYMS INSTALLKERNEL PERL PYTHON UTS_MACHINE - export HOSTCXX HOSTCXXFLAGS LDFLAGS_MODULE CHECK CHECKFLAGS +-export ARCH SRCARCH CONFIG_SHELL HOSTCC KBUILD_HOSTCFLAGS CROSS_COMPILE AS LD CC +-export CPP AR NM STRIP OBJCOPY OBJDUMP KBUILD_HOSTLDFLAGS KBUILD_HOSTLDLIBS ++export ARCH SRCARCH SUBARCH CONFIG_SHELL HOSTCC KBUILD_HOSTCFLAGS CROSS_COMPILE AS LD ++export CC CPP AR NM STRIP OBJCOPY OBJDUMP KBUILD_HOSTLDFLAGS KBUILD_HOSTLDLIBS + export MAKE LEX YACC AWK GENKSYMS INSTALLKERNEL PERL PYTHON PYTHON2 PYTHON3 UTS_MACHINE + export HOSTCXX KBUILD_HOSTCXXFLAGS LDFLAGS_MODULE CHECK CHECKFLAGS diff --git a/target/linux/generic/backport-4.19/012-kbuild-add-macro-for-controlling-warnings-to-linux-c.patch b/target/linux/generic/backport-4.19/012-kbuild-add-macro-for-controlling-warnings-to-linux-c.patch deleted file mode 100644 index 7617c2e5f5..0000000000 --- a/target/linux/generic/backport-4.19/012-kbuild-add-macro-for-controlling-warnings-to-linux-c.patch +++ /dev/null @@ -1,140 +0,0 @@ -From: Arnd Bergmann -Date: Tue, 19 Jun 2018 13:14:56 -0700 -Subject: [PATCH] kbuild: add macro for controlling warnings to - linux/compiler.h - -I have occasionally run into a situation where it would make sense to -control a compiler warning from a source file rather than doing so from -a Makefile using the $(cc-disable-warning, ...) or $(cc-option, ...) -helpers. - -The approach here is similar to what glibc uses, using __diag() and -related macros to encapsulate a _Pragma("GCC diagnostic ...") statement -that gets turned into the respective "#pragma GCC diagnostic ..." by -the preprocessor when the macro gets expanded. - -Like glibc, I also have an argument to pass the affected compiler -version, but decided to actually evaluate that one.

Clang supports - more warnings than GCC, and we probably want to classify them - as default, W=1, W=2 etc, but there are cases in which the - warnings should be classified differently due to excessive false - positives from one or the other compiler. - -- Adding a way to turn the default warnings into errors (e.g. using - a new "make E=0" tag) while not also turning the W=1 warnings into - errors. - -This patch for now just adds the minimal infrastructure in order to -do the first of the list above.
