2019-10-28riscv: add missing header file includesPaul Walmsley
sparse identifies several missing prototypes caused by missing preprocessor include directives: arch/riscv/kernel/cpufeature.c:16:6: warning: symbol 'has_fpu' was not declared. Should it be static? arch/riscv/kernel/process.c:26:6: warning: symbol 'arch_cpu_idle' was not declared.

Should it be static? arch/riscv/mm/context.c:42:6: warning: symbol 'switch_mm' was not declared. Should it be static? Fix by including the appropriate header files in the appropriate source files.

2019-10-28riscv: mark some code and data as file-staticPaul Walmsley
Several functions and arrays which are only used in the files in which they are declared are missing "static" qualifiers. Warnings for these symbols are reported by sparse: arch/riscv/kernel/vdso.c:28:18: warning: symbol 'vdso_data' was not declared. Should it be static? arch/riscv/mm/sifive_l2_cache.c:145:12: warning: symbol 'sifive_l2_init' was not declared. Should it be static? Resolve these warnings by marking them as static. This version incorporates feedback from Greentime Hu <greentime.hu@sifive.com>.

2019-07-01riscv: Remove gate area stubsAndy Lutomirski
Since commit a6c19dfe3994 ("arm64,ia64,ppc,s390,sh,tile,um,x86,mm: remove default gate area"), which predates riscv's inclusion in Linux by almost three years, the default behavior wrt the gate area is sane. Remove riscv's gate area stubs.

2019-03-05riscv/vdso: don't clear PG_reservedDavid Hildenbrand
The VDSO is part of the kernel image and therefore the struct pages are marked as reserved during boot. As we install a special mapping, the actual struct pages will never be exposed to MM via the page tables. We can therefore leave the pages marked as reserved.
