Here's what the diffstat and patch looks like when you combine the original commit and the three fixes. The LoC delta of 25 lines can be accounted for as deleted commentry. So, I think (as I've detailed above) that the _technical_ benefit of the approach is very low. If we want to move the exports into assembly files, I've no problem with that, provided we can do it better than this - and by better I mean not creating the fragile asm-prototypes.h which divorses the prototypes from everything else. Looking at _this_ patch, there's also an issue with the __raw_* functions which are conditionally exported, which isn't taken account of in these fixes. We currently build most of the io-*.S files whether we use them or not, and rely on the linker's archive processing, along with the ifdefs in armksyms to omit them from the kernel image. This won't happen with this new approach. So, I'm reverting the original commit today, because there's no clear benefit, it's fragile, and I think there's still a few corner cases that need to be fixed. We can revisit when we have more time to properly review and test these changes, rather than at what is now the 11th hour. arch/arm/include/asm/Kbuild | 1 + arch/arm/include/asm/asm-prototypes.h | 34 +++++++ arch/arm/kernel/Makefile | 2 +- arch/arm/kernel/armksyms.c | 183 ---------------------------------- arch/arm/kernel/entry-ftrace.S | 3 + arch/arm/kernel/head.S | 3 + arch/arm/kernel/io.c | 7 ++ arch/arm/kernel/smccc-call.S | 3 + arch/arm/lib/ashldi3.S | 3 + arch/arm/lib/ashrdi3.S | 3 + arch/arm/lib/bswapsdi2.S | 3 + arch/arm/lib/changebit.S | 3 + arch/arm/lib/clear_user.S | 4 + arch/arm/lib/clearbit.S | 3 + arch/arm/lib/copy_from_user.S | 2 + arch/arm/lib/copy_page.S | 2 + arch/arm/lib/copy_to_user.S | 4 + arch/arm/lib/csumipv6.S | 3 +- arch/arm/lib/csumpartial.S | 2 + arch/arm/lib/csumpartialcopy.S | 1 + arch/arm/lib/csumpartialcopygeneric.S | 2 + arch/arm/lib/csumpartialcopyuser.S | 1 + arch/arm/lib/delay.c | 2 + arch/arm/lib/div64.S | 2 + arch/arm/lib/findbit.S | 9 ++ arch/arm/lib/getuser.S | 9 ++ arch/arm/lib/io-readsb.S | 2 + arch/arm/lib/io-readsl.S | 2 + arch/arm/lib/io-readsw-armv3.S | 3 +- arch/arm/lib/io-readsw-armv4.S | 2 + arch/arm/lib/io-writesb.S | 2 + arch/arm/lib/io-writesl.S | 2 + arch/arm/lib/io-writesw-armv3.S | 2 + arch/arm/lib/io-writesw-armv4.S | 2 + arch/arm/lib/lib1funcs.S | 9 ++ arch/arm/lib/lshrdi3.S | 3 + arch/arm/lib/memchr.S | 2 + arch/arm/lib/memcpy.S | 2 + arch/arm/lib/memmove.S | 2 + arch/arm/lib/memset.S | 2 + arch/arm/lib/memzero.S | 2 + arch/arm/lib/muldi3.S | 3 + arch/arm/lib/putuser.S | 5 + arch/arm/lib/setbit.S | 3 + arch/arm/lib/strchr.S | 2 + arch/arm/lib/strrchr.S | 2 + arch/arm/lib/testchangebit.S | 3 + arch/arm/lib/testclearbit.S | 3 + arch/arm/lib/testsetbit.S | 3 + arch/arm/lib/uaccess_with_memcpy.c | 3 + arch/arm/lib/ucmpdi2.S | 3 + arch/arm/mach-imx/Makefile | 1 - arch/arm/mach-imx/ssi-fiq-ksym.c | 20 ---- arch/arm/mach-imx/ssi-fiq.S | 7 +- 54 files changed, 183 insertions(+), 208 deletions(-) diff --git a/arch/arm/include/asm/Kbuild b/arch/arm/include/asm/Kbuild index 55e0e3ea9cb6..0745538b26d3 100644 --- a/arch/arm/include/asm/Kbuild +++ b/arch/arm/include/asm/Kbuild @@ -8,6 +8,7 @@ generic-y += early_ioremap.h generic-y += emergency-restart.h generic-y += errno.h generic-y += exec.h +generic-y += export.h generic-y += ioctl.h generic-y += ipcbuf.h generic-y += irq_regs.h diff --git a/arch/arm/include/asm/asm-prototypes.h b/arch/arm/include/asm/asm-prototypes.h new file mode 100644 index 000000000000..04e5616a7b15 --- /dev/null +++ b/arch/arm/include/asm/asm-prototypes.h @@ -0,0 +1,34 @@ +#include <linux/arm-smccc.h> +#include <linux/bitops.h> +#include <linux/ftrace.h> +#include <linux/io.h> +#include <linux/platform_data/asoc-imx-ssi.h> +#include <linux/string.h> +#include <linux/uaccess.h> + +#include <asm/checksum.h> +#include <asm/div64.h> +#include <asm/memory.h> + +extern void __aeabi_idivmod(void); +extern void __aeabi_idiv(void); +extern void __aeabi_lasr(void); +extern void __aeabi_llsl(void); +extern void __aeabi_llsr(void); +extern void __aeabi_lmul(void); +extern void __aeabi_uidivmod(void); +extern void __aeabi_uidiv(void); +extern void __aeabi_ulcmp(void); + +extern void __ashldi3(void); +extern void __ashrdi3(void); +extern void __bswapdi2(void); +extern void __bswapsi2(void); +extern void __divsi3(void); +extern void __do_div64(void); +extern void __lshrdi3(void); +extern void __modsi3(void); +extern void __muldi3(void); +extern void __ucmpdi2(void); +extern void __udivsi3(void); +extern void __umodsi3(void); diff --git a/arch/arm/kernel/Makefile b/arch/arm/kernel/Makefile index ad325a8c7e1e..68c2c097cffe 100644 --- a/arch/arm/kernel/Makefile +++ b/arch/arm/kernel/Makefile @@ -33,7 +33,7 @@ endif obj-$(CONFIG_CPU_IDLE) += cpuidle.o obj-$(CONFIG_ISA_DMA_API) += dma.o obj-$(CONFIG_FIQ) += fiq.o fiqasm.o -obj-$(CONFIG_MODULES) += armksyms.o module.o +obj-$(CONFIG_MODULES) += module.o obj-$(CONFIG_ARM_MODULE_PLTS) += module-plts.o obj-$(CONFIG_ISA_DMA) += dma-isa.o obj-$(CONFIG_PCI) += bios32.o isa.o diff --git a/arch/arm/kernel/armksyms.c b/arch/arm/kernel/armksyms.c deleted file mode 100644 index 7e45f69a0ddc..000000000000 --- a/arch/arm/kernel/armksyms.c +++ /dev/null @@ -1,183 +0,0 @@ -/* - * linux/arch/arm/kernel/armksyms.c - * - * Copyright (C) 2000 Russell King - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. - */ -#include <linux/export.h> -#include <linux/sched.h> -#include <linux/string.h> -#include <linux/cryptohash.h> -#include <linux/delay.h> -#include <linux/in6.h> -#include <linux/syscalls.h> -#include <linux/uaccess.h> -#include <linux/io.h> -#include <linux/arm-smccc.h> - -#include <asm/checksum.h> -#include <asm/ftrace.h> - -/* - * libgcc functions - functions that are used internally by the - * compiler...
