d04adc383f gcc-12: disable '-Wdangling-pointer' warning for now 
commit f7d63b50898172b9eb061b9e2daad61b428792d0 upstream.

[ Upstream commit 49beadbd47c270a00754c107a837b4f29df4c822 ]

While the concept of checking for dangling pointers to local variables
at function exit is really interesting, the gcc-12 implementation is not
compatible with reality, and results in false positives.

For example, gcc sees us putting things on a local list head allocated
on the stack, which involves exactly those kinds of pointers to the
local stack entry:

  In function ‘__list_add’,
      inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
      inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
  include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
     74 |         new->prev = prev;
        |         ~~~~~~~~~~^~~~~~

But then gcc - understandably - doesn't really understand the big
picture how the doubly linked list works, so doesn't see how we then end
up emptying said list head in a loop and the pointer we added has been
removed.

Gcc also complains about us (intentionally) using this as a way to store
a kind of fake stack trace, eg

  drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
     40 |         acpi_gbl_entry_stack_pointer = &current_sp;
        |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~

which is entirely reasonable from a compiler standpoint, and we may want
to change those kinds of patterns, but not not.

So this is one of those "it would be lovely if the compiler were to
complain about us leaving dangling pointers to the stack", but not this
way.

b3d346ece9 kbuild: Port silent mode detection to future gnu make. 
commit 4bf73588165ba7d32131a043775557a54b6e1db5 upstream.

Port silent mode detection to the future (post make-4.4) versions of gnu make.

Makefile contains the following piece of make code to detect if option -s is
specified on the command line.

ifneq ($(findstring s,$(filter-out --%,$(MAKEFLAGS))),)

This code is executed by make at parse time and assumes that MAKEFLAGS
does not contain command line variable definitions.
Currently if the user defines a=s on the command line, then at build only
time MAKEFLAGS contains " -- a=s".
However, starting with commit dc2d963989b96161472b2cd38cef5d1f4851ea34
MAKEFLAGS contains command line definitions at both parse time and
build time.

This '-s' detection code then confuses a command line variable
definition which contains letter 's' with option -s.

$ # old make
$ make net/wireless/ocb.o a=s
  CALL    scripts/checksyscalls.sh
  DESCEND objtool
$ # this a new make which defines makeflags at parse time
$ ~/src/gmake/make/l64/make net/wireless/ocb.o a=s
$

We can see here that the letter 's' from 'a=s' was confused with -s.

This patch checks for presence of -s using a method recommended by the
make manual here
https://www.gnu.org/software/make/manual/make.html#Testing-Flags.

2f1b3377b6 Makefile.debug: re-enable debug info for .S files 
This is _not_ an upstream commit and just for 5.4.y only. It is based
on commit 32ef9e5054ec0321b9336058c58ec749e9c6b0fe upstream.

Alexey reported that the fraction of unknown filename instances in
kallsyms grew from ~0.3% to ~10% recently; Bill and Greg tracked it down
to assembler defined symbols, which regressed as a result of:

commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1")

In that commit, I allude to restoring debug info for assembler defined
symbols in a follow up patch, but it seems I forgot to do so in

commit a66049e2cf0e ("Kbuild: make DWARF version a choice")

635e8e6f68 Makefile: link with -z noexecstack --no-warn-rwx-segments 
commit 0d362be5b14200b77ecc2127936a5ff82fbffe41 upstream.

Users of GNU ld (BFD) from binutils 2.39+ will observe multiple
instances of a new warning when linking kernels in the form:

  ld: warning: vmlinux: missing .note.GNU-stack section implies executable stack
  ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
  ld: warning: vmlinux has a LOAD segment with RWX permissions

Generally, we would like to avoid the stack being executable.  Because
there could be a need for the stack to be executable, assembler sources
have to opt-in to this security feature via explicit creation of the
.note.GNU-stack feature (which compilers create by default) or command
line flag --noexecstack.  Or we can simply tell the linker the
production of such sections is irrelevant and to link the stack as
--noexecstack.

LLVM's LLD linker defaults to -z noexecstack, so this flag isn't
strictly necessary when linking with LLD, only BFD, but it doesn't hurt
to be explicit here for all linkers IMO.  --no-warn-rwx-segments is
currently BFD specific and only available in the current latest release,
so it's wrapped in an ld-option check.

While the kernel makes extensive usage of ELF sections, it doesn't use
permissions from ELF segments.
