+Subject: [PATCH] Fix for "kmem -s|-S" option on Linux 5.7 and later kernels
+
+Linux 5.7 and later kernels that contain kernel commit 1ad53d9fa3f6
+("slub: improve bit diffusion for freelist ptr obfuscation") changed
+the calculation formula in the freelist_ptr(), which added a swab()
+call to mix bits a little more. When kernel is configured with the
+"CONFIG_SLAB_FREELIST_HARDENED=y", without the patch, the "kmem -s|-S"
+options display wrong statistics and state whether slab objects are
+in use or free and can print the following errors:

+ configuration value
+
+On RHEL9, crash hits a bug when executing "crash /proc/kcore":
+seek error: kernel virtual address: ffff6a0f3fff0000 type: "pmd page"
+
+The kernel virtual address does not vary with vabits_actual, instead,
+is determined by configuration value. But crash does not observe this
+fact.
+
+Since vabits_actual related kernel commit is introduced after arm64
+mm layout flip commit, so changes are safe under the condition if
+(ms->VA_BITS_ACTUAL), and keep the else branch untouched.

+Subject: [PATCH 3/4] arm64: use dedicated bits to record the VA space layout
+ changes
+
+arm64 memory layout experiences big changes due to the following kernel
+commits in date descending order:
+ 5. 7bc1a0f9e176 arm64: mm: use single quantity to represent the PA to VA translation
+ 4. b6d00d47e81a arm64: mm: Introduce 52-bit Kernel VAs
+ 3. 5383cc6efed1 arm64: mm: Introduce vabits_actual
+ 2. 14c127c957c1 arm64: mm: Flip kernel VA space
+ 1. f80fb3a3d508 arm64: add support for kernel ASLR
+
+For 1, crash has already used NEW_VMEMMAP to trace it.
+For 2, crash lacks a flag to tag it and handle it differently.
+For 3, two important kernel variables vabits_actual and physvirt_offset
+are introduced.
+For 4, since it comes immediately after 3, crash-utility does not need
+to distinguish it.
+For 5, kernel variable phyvirt_offset is removed
+
+These changes have effects on PTOV()/VTOP() formula. So introducing
+two bits HAS_PHYSVIRT_OFFSET and FLIPPED_VM as hint to apply different
+formula.

+Subject: [PATCH 4/4] arm64: implement switchable PTOV()/VTOP() for kernels >=
+ 5.10
+
+Crash encounters a bug like the following:
+ ...
+ SECTION_SIZE_BITS: 30
+ CONFIG_ARM64_VA_BITS: 52
+ VA_BITS_ACTUAL: 48
+ (calculated) VA_BITS: 48
+ PAGE_OFFSET: ffff000000000000
+ VA_START: ffff800000000000
+ modules: ffff800008000000 - ffff80000fffffff
+ vmalloc: ffff800010000000 - ffffffdfdffeffff
+ kernel image: ffff800010000000 - ffff800012750000
+ vmemmap: ffffffdfffe00000 - ffffffffffffffff
+
+ <readmem: ffff800011c53bc8, KVADDR, "nr_irqs", 4, (FOE), b47bdc>
+ <read_kdump: addr: ffff800011c53bc8 paddr: eb453bc8 cnt: 4>
+ read_netdump: addr: ffff800011c53bc8 paddr: eb453bc8 cnt: 4 offset: 1c73bc8
+ irq_stack_ptr:
+ type: 1, TYPE_CODE_PTR
+ target_typecode: 8, TYPE_CODE_INT
+ target_length: 8
+ length: 8
+ GNU_GET_DATATYPE[thread_union]: returned via gdb_error_hook
+ <readmem: ffff000b779c0050, KVADDR, "IRQ stack pointer", 8, (ROE), 3a37bea0>
+ <read_kdump: addr: ffff000b779c0050 paddr: fff1000bf79c0050 cnt: 8>
+ read_netdump: READ_ERROR: offset not found for paddr: fff1000bf79c0050
+ crash: read error: kernel virtual address: ffff000b779c0050 type: "IRQ stack pointer"
+ ...
+
+Apparently, for a normal system, the 'paddr: fff1000bf79c0050' is
+unreasonable.
+
+This bug connects with kernel commit 7bc1a0f9e176 ("arm64: mm: use
+single quantity to represent the PA to VA translation"), which removed
+physvirt_offset kernel variable and changed the PTOV()/VTOP() formulas.
+
+Implement switchable PTOV()/VTOP() to cope with different kernel
+version.
