The quilt patch titled Subject: kernel/sys_ni: add compat entry for fadvise64_64 has been removed from the -mm tree. Its filename was kernel-sys_ni-add-compat-entry-for-fadvise64_64.patch
This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------ From: Randy Dunlap rdunlap@infradead.org Subject: kernel/sys_ni: add compat entry for fadvise64_64 Date: Sun, 7 Aug 2022 15:09:34 -0700
When CONFIG_ADVISE_SYSCALLS is not set/enabled and CONFIG_COMPAT is set/enabled, the riscv compat_syscall_table references 'compat_sys_fadvise64_64', which is not defined:
riscv64-linux-ld: arch/riscv/kernel/compat_syscall_table.o:(.rodata+0x6f8): undefined reference to `compat_sys_fadvise64_64'
Add 'fadvise64_64' to kernel/sys_ni.c as a conditional COMPAT function so that when CONFIG_ADVISE_SYSCALLS is not set, there is a fallback function available.
