+Subject: [PATCH 01/14] Fix "rd" command for zram data display in Linux 6.2 and
+ later
+
+Kernel commit 7ac07a26dea7 ("zram: preparation for multi-zcomp support")
+replaced "compressor" member with "comp_algs" in the zram struct.
+Without the patch, the "rd" command can triggers the following error:
+
+  rd: WARNING: Some pages are swapped out to zram. Please run mod -s zram.
+  rd: invalid user virtual address: ffff7d23f010  type: "64-bit UVADDR"
+
+Related kernel commit:
+  84b33bf78889 ("zram: introduce recompress sysfs knob")

+Subject: [PATCH 03/14] zram: Fixes for lookup_swap_cache()
+
+Fix the following three issues:
+(1) swap cache missing page tree offset
+    The radix or xarray start at an offset inside struct address_space.
+(2) swap cache entries are pointer to struct page
+    The entries in radix, xarray (swap cache) are address to struct page.
+(3) exclude shadow entries from swap cache lookup
+    radix or xarray can contain shadow entries from previous page
+    entries. These should be ignored when looking for a page pointer.
+
+Without the patch,
+- lookup_swap_cache() returns NULL since do_xarray() call returns FALSE,
+- in try_zram_decompress(), since 'entry' is NULL, page is filled with 0,
+    if (!entry || (flags & ZRAM_FLAG_SAME_BIT)) {
+and pages in swap cache will be seen to be a 'zero' page.

+
+For the stacktrace of "dis -rl", it calls dw2_expand_all_symtabs() to expand
+all symtable of the objfile, or "*.ko.debug" in our case. However for
+the stacktrace of "bt", it doesn't expand all, but only a subset of symtable
+which is enough to find a symbol by dw2_lookup_symbol(). As a result, the
+objfile->compunit_symtabs, which is the head of a single linked list of
+struct compunit_symtab, is not NULL but didn't contain all symtables. It
+will not be reinitialized in gdb_get_line_number() by "dis -rl" because
+!objfile_has_full_symbols(objfile) check will fail, so it cannot display
+the proper code line number data.
+
+Since objfile_has_full_symbols(objfile) check cannot ensure all symbols
+been expanded, this patch add a new member as a flag for struct objfile
+to record if all symbols have been expanded. The flag will be set only ofter
+expand_all_symtabs been called.

+Subject: [PATCH 05/14] symbols: skip load .init.* sections if module was
+ successfully initialized
+
+There might be address overlap of one modules .init.text symbols and
+another modules .text symbols. As a result, gdb fails to translate the
+address to symbol name correctly:
+
+  crash> sym -m virtio_blk | grep MODULE
+  ffffffffc00a4000 MODULE START: virtio_blk
+  ffffffffc00a86ec MODULE END: virtio_blk
+  crash> gdb info address floppy_module_init
+  Symbol "floppy_module_init" is a function at address 0xffffffffc00a4131.
+
+Since the .init.* sections of a module had been freed by kernel if the
+module was initialized successfully, there is no need to load the .init.*
+sections data from "*.ko.debug" in gdb to create such an overlap.
+lm->mod_init_module_ptr is used as a flag of whether module is freed.
+
+Without the patch:

+In 5.12 the following change was introduced:
+b6038942480e ("mm: memcg: add swapcache stat for memcg v2")
+
+Then the variable 'nr_swapper_spaces' is not read (unless
+CONFIG_DEBUG_VM=y).  In GKI builds this variable is then optimized
+out. But the same change provided a new way to obtain the same

+Subject: [PATCH 11/14] RISCV64: Fix 'bt' output when no ra on the stack top
+
+Same as the Linux commit f766f77a74f5 ("riscv/stacktrace: Fix
+stack output without ra on the stack top").
+
+When a function doesn't have a callee, then it will not
+push ra into the stack, such as lkdtm functions, so
+correct the FP of the second frame and use pt_regs to get
+the right PC of the second frame.
+
+Before this patch, the `bt -f` outputs only the first frame with
+the wrong PC and FP of next frame:
+```
+crash> bt -f
+PID: 1        TASK: ff600000000e0000  CPU: 1    COMMAND: "sh"
+ #0 [ff20000000013cf0] lkdtm_EXCEPTION at ffffffff805303c0
+    [PC: ffffffff805303c0 RA: ff20000000013d10 SP: ff20000000013cf0 SIZE: 16] <- wrong next PC
+    ff20000000013cf0: 0000000000000001 ff20000000013d10 <- next FP
+    ff20000000013d00: ff20000000013d40
+crash>
+```
+After this patch, the `bt` outputs the full frames:
+```
+crash> bt
+PID: 1        TASK: ff600000000e0000  CPU: 1    COMMAND: "sh"
+ #0 [ff20000000013cf0] lkdtm_EXCEPTION at ffffffff805303c0

+
+"kmem -l" option has existed when crash git project initialization, but

+
+In addition, those symbols required by the -l option were for very old

+not been fixed for a long time.

+Instead of document this option, hide it from help messages.

+Subject: [PATCH 14/14] x86_64: check bt->bptr before calculate framesize
+
+Previously the value of bt->bptr is not checked, which may led to a
+wrong prev_sp and framesize. As a result, bt->stackbuf[] will be
+accessed out of range, and segfault.

+Check bt->bptr value before calculate framesize. Only bt->bptr within
