Merge tag 'riscv-for-linus-7.2-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Paul Walmsley:

 - Prevent get_free_mem_region() from returning regions that are
   unmappable in certain circumstances by defining
   DIRECT_MAP_PHYSMEM_END for RISC-V

 - Fix an early boot problem with kexec_file when the amount of
   installed physical memory installed on the system exceeds the direct
   map size, which is possible in certain RISC-V virtual memory modes

 - Unconditionally sfence.vma in the new vmalloc area handling code in
   the page fault handler, since even the presence of Svvptc doesn't
   guarantee that the CPU won't immediately fault again after the
   exception handler completes and subsequently crash

 - Fix ftrace_graph_ret_addr() to use the correct task pointer (aligning
   with what other architectures do)

 - Fix the misaligned access performance checking code in cases when
   performance is specified on the kernel command line and when CPUs
   have been brought offline and back online

 - Get rid of a bogus address offset in the non-frame-pointer version of
   walk_stackframe(), aligning it with the frame pointer-based code

 - Fix a RISC-V kfence issue causing bogus use-after-free warnings

 - Add ARCH_HAS_CC_CAN_LINK for RISC-V, which needs different compiler
   command line flags than other architectures

 - Implement _THIS_IP_ using RISC-V-specific assembly, which seems to be
   less brittle (from a compiler point of view) than taking the address
   of a label

 - Reduce kernel startup overhead by defining
   HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
   requirements

 - Patch the CFI vDSO during alternatives processing, not only the
   standard vDSO

 - Fix a potential memory leak in the cacheinfo code

 - Clean up kernel/setup.c:add_resource() to pass along the return value
   from insert_resource() and to improve the display of resource ranges

 - Clean up our purgatory.[ch] by aligning our purgatory() prototype to
   what's in arch/x86, and by cleaning up verify_sha256_digest()

 - Clean up cpu_is_stopped() to align its function a little more closely
   to its name

 - Replace some unbounded string function usage in get_early_cmdline()
   and the ptdump code with strscpy()

 - Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
   safer bounds checking

 - Standardize how compiler output flags are specified in the RISC-V
   kselftests, aligning them with what other architectures do

 - Use the Linux-generic cmp_int() macro in place of an open-coded
   "cmp_3way()" macro in kernel/module-sections.c

 - Panic early in boot if IRQ handler stacks can't be allocated rather
   than pretending to continue normally

 - Add support for Eswin SoCs in the RISC-V defconfig

 - Remove some unnecessary conditionals in sbi_hsm_hart_{start,stop}()

 - Clean up some Kconfig infelicities found by Kconfirm

 - Replace an open-coded version of min() in the kexec_elf code with
   the standard min() function
