[PATCH] tty: Revert the removal of the Cyclades public API

by Maciej W. Rozycki

Fix a user API regression introduced with commit f76edd8f7ce0 ("tty: cyclades, remove this orphan"), which removed a part of the API and caused compilation errors for user programs using said part, such as GCC 9 in its libsanitizer component[1]: .../libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:160:10: fatal error: linux/cyclades.h: No such file or directory 160 | #include <linux/cyclades.h> | ^~~~~~~~~~~~~~~~~~ compilation terminated. make[4]: *** [Makefile:664: sanitizer_platform_limits_posix.lo] Error 1 Any part of the public API is a contract between the kernel and the userland and therefore once there it must not be removed even if its implementation side has gone and any relevant calls will now fail unconditionally. Revert the part of the commit referred then that affects the user API, bringing the most recent version of <linux/cyclades.h> back verbatim modulo the removal of trailing whitespace which used to be there, and updating <linux/major.h> accordingly.

[PATCH] phy: ti: Fix "BUG: KASAN: global-out-of-bounds in _get_maxdiv" issue

_get_table_maxdiv() tries to access "clk_div_table" array out of bound defined in phy-j721e-wiz.c. Add a sentinel entry to prevent the following global-out-of-bounds error reported by enabling KASAN.

[PATCH] ksmbd: fix SMB 3.11 posix extension mount failure

cifs client set 4 to DataLength of create_posix context, which mean Mode variable of create_posix context is only available.
