Please apply commit ebe559609d78 ("fs: get rid of __FMODE_NONOTIFY kludge") to v6.12.y

[Guenter Roeck]

Hi,

all sparc32 and sparc64 builds in v6.12.y fail as follows.

Building sparc32:defconfig ... failed
--------------
Error log:
<stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp]
kernel/fork.c: In function '__do_sys_clone3':
kernel/fork.c:3114:2: warning: #warning clone3() entry point is missing, please fix [-Wcpp]
  3114 | #warning clone3() entry point is missing, please fix
       |  ^~~~~~~
In file included from <command-line>:
fs/fcntl.c: In function 'fcntl_init':
include/linux/compiler_types.h:543:45: error: call to '__compiletime_assert_325' declared with attribute error: BUILD_BUG_ON failed: 21 - 1 != HWEIGHT32( (VALID_OPEN_FLAGS & ~(O_NONBLOCK | O_NDELAY)) | __FMODE_EXEC | __FMODE_NONOTIFY)
   543 |         _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

Bisect points to commit 07ee6057f92a ("fsnotify: opt-in for permission events
at file open time"). See bisect log below for reference.

Please apply commit ebe559609d78 ("fs: get rid of __FMODE_NONOTIFY kludge")
to v6.12.y to fix the problem (assuming there is interest in sparc builds
on v6.12.y kernels - this has been broken since v6.12.105).

Thanks,
Guenter
