| 2021-03-04 | Take mmap lock in cacheflush syscall | Jann Horn | |
| [ Upstream commit c26958cb5a0d9053d1358258827638773f3d36ed ] We need to take the mmap lock around find_vma() and subsequent use of the VMA. Otherwise, we can race with concurrent operations like munmap(), which can lead to use-after-free accesses to freed VMAs.

| 2014-12-08 | nios2: System calls handling | Ley Foon Tan | |
| This patch adds support for system calls from userspaces. It uses the asm-generic/unistd.h definitions with architecture spcific syscall. The sys_call_table is just an array defined in a C file and it contains pointers to the syscall functions. Signed-off-by: Ley Foon Tan <lftan@altera.com> | |||
