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:
crash> kmem -s

Subject: [PATCH 1/2] memory: Add support for SECTION_TAINT_ZONE_DEVICE flag
Fix for "kmem -n|-p" options on Linux 5.12-rc1 and later kernels
that contain commit 1f90a3477df3f ("mm: teach pfn_to_online_page()
about ZONE_DEVICE section collisions"). Without the patch, the
"kmem -n" option incorrectly shows mem_map addresses containing the
flag in bit 5 as part of the virtual address, and also the "kmem -p"
option shows page structures at wrong position. With the patch,
the "kmem -n" option displays the new "D" state flag.

Subject: [PATCH 2/4] arm64: assign page_offset with VA_BITS kernel
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.

The nid member of struct memory_block is a 4-byte integer, but read

commit e9a2e48e8704c ("drivers/base/memory: don't store phys_device

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.

From f53b73e8380bca054cebd2b61ff118c46609429b Mon Sep 17 00:00:00 2001
From: Pingfan Liu <piliu@redhat.com>
Date: Fri, 2 Jul 2021 10:14:24 +0800
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.

does not not typedef u32 as done in include/asm-x86/types.h.

init_handler_platform() is inlined into ia64_init_handler();
properly handles both RHEL3 and RHEL4 kernel patches.
