Pull ARM updates from Russell King: "Updates for IRQ stacks and virtually mapped stack support, and ftrace: - Support for IRQ and vmap'ed stacks This covers all the work related to implementing IRQ stacks and vmap'ed stacks for all 32-bit ARM systems that are currently supported by the Linux kernel, including RiscPC and Footbridge. It has been submitted for review in four different waves: - IRQ stacks support for v7 SMP systems [0] - vmap'ed stacks support for v7 SMP systems[1] - extending support for both IRQ stacks and vmap'ed stacks for all remaining configurations, including v6/v7 SMP multiplatform kernels and uniprocessor configurations including v7-M [2] - fixes and updates in [3] - ftrace fixes and cleanups Make all flavors of ftrace available on all builds, regardless of ISA choice, unwinder choice or compiler [4]: - use ADD not POP where possible - fix a couple of Thumb2 related issues - enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness - enable the graph tracer with the EABI unwinder - avoid clobbering frame pointer registers to make Clang happy - Fixes for the above" [0] https://lore.kernel.org/linux-arm-kernel/20211115084732.3704393-1-ardb@kernel.org/ [1] https://lore.kernel.org/linux-arm-kernel/20211122092816.2865873-1-ardb@kernel.org/ [2] https://lore.kernel.org/linux-arm-kernel/20211206164659.1495084-1-ardb@kernel.org/ [3] https://lore.kernel.org/linux-arm-kernel/20220124174744.1054712-1-ardb@kernel.org/ [4] https://lore.kernel.org/linux-arm-kernel/20220203082204.1176734-1-ardb@kernel.org/ * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (62 commits) ARM: fix building NOMMU ARMv4/v5 kernels ARM: unwind: only permit stack switch when unwinding call_with_stack() ARM: Revert "unwind: dump exception stack from calling frame" ARM: entry: fix unwinder problems caused by IRQ stacks ARM: unwind: set frame.pc correctly for current-thread unwinding ARM: 9184/1: return_address: disable again for CONFIG_ARM_UNWIND=y ARM: 9183/1: unwind: avoid spurious warnings on bogus code addresses Revert "ARM: 9144/1: forbid ftrace with clang and thumb2_kernel" ARM: mach-bcm: disable ftrace in SMC invocation routines ARM: cacheflush: avoid clobbering the frame pointer ARM: kprobes: treat R7 as the frame pointer register in Thumb2 builds ARM: ftrace: enable the graph tracer with the EABI unwinder ARM: unwind: track location of LR value in stack frame ARM: ftrace: enable HAVE_FUNCTION_GRAPH_FP_TEST ARM: ftrace: avoid unnecessary literal loads ARM: ftrace: avoid redundant loads or clobbering IP ARM: ftrace: use trampolines to keep .init.text in branching range ARM: ftrace: use ADD not POP to counter PUSH at entry ARM: ftrace: ensure that ADR takes the Thumb bit into account ARM: make get_current() and __my_cpu_offset() __always_inline ...
