  "message": "Kbuild: use -fshort-wchar globally\n\nCommit 971a69db7dc0 (\"Xen: don\u0027t warn about 2-byte wchar_t in efi\")\nadded the --no-wchar-size-warning to the Makefile to avoid this\nharmless warning:\n\narm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail\n\nChanging kbuild to use thin archives instead of recursive linking\nunfortunately brings the same warning back during the final link.\n\nThe kernel does not use wchar_t string literals at this point, and\nxen does not use wchar_t at all (only efi_char16_t), so the flag\nhas no effect, but as pointed out by Jan Beulich, adding a wchar_t\nstring literal would be bad here.\n\nSince wchar_t is always defined as u16, independent of the toolchain\ndefault, always passing -fshort-wchar is correct and lets us\nremove the Xen specific hack along with fixing the warning.\n\nLink: https://patchwork.kernel.org/patch/9275217/\nFixes: 971a69db7dc0 (\"Xen: don\u0027t warn about 2-byte wchar_t in efi\")\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: David Vrabel \u003cdavid.vrabel@citrix.com\u003e\nSigned-off-by: Masahiro Yamada \u003cyamada.masahiro@socionext.com\u003e\n",
