stable inclusion from linux-4.19.206 commit 7027119349fe919c39a3f75de1f8d77fe6cb1a98
--------------------------------
[ Upstream commit bf79167fd86f3b97390fe2e70231d383526bd9cc ]
Enabling CONFIG_STACKDEPOT results in the following build error.
arc-elf-ld: lib/stackdepot.o: in function `filter_irq_stacks': stackdepot.c:(.text+0x456): undefined reference to `__irqentry_text_start' arc-elf-ld: stackdepot.c:(.text+0x456): undefined reference to `__irqentry_text_start' arc-elf-ld: stackdepot.c:(.text+0x476): undefined reference to `__irqentry_text_end' arc-elf-ld: stackdepot.c:(.text+0x476): undefined reference to `__irqentry_text_end' arc-elf-ld: stackdepot.c:(.text+0x484): undefined reference to `__softirqentry_text_start' arc-elf-ld: stackdepot.c:(.text+0x484): undefined reference to `__softirqentry_text_start' arc-elf-ld: stackdepot.c:(.text+0x48c): undefined reference to `__softirqentry_text_end' arc-elf-ld: stackdepot.c:(.text+0x48c): undefined reference to `__softirqentry_text_end'
Other architectures address this problem by adding IRQENTRY_TEXT and SOFTIRQENTRY_TEXT to the text segment, so do the same here.
