riscv: add missing header file includes

2019-10-28T07:46:01Z

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/kernel/reset.c:15:6: warning: symbol 'pm_power_off' was not declared.

Should it be static? arch/riscv/kernel/traps.c:149:13: warning: symbol 'trap_init' 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. This patch should have no functional impact. Signed-off-by: Paul Walmsley Reviewed-by: Christoph Hellwig

riscv: mark some code and data as file-static

2019-10-28T07:46:01Z

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.

riscv: Remove gate area stubs

2019-07-01T20:13:36Z

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. Cc: Palmer Dabbelt Cc: Albert Ou Cc: linux-riscv@lists.infradead.org Signed-off-by: Andy Lutomirski Reviewed-by: Christoph Hellwig Signed-off-by: Paul Walmsley

riscv/vdso: don't clear PG_reserved

2019-03-06T05:07:18Z

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.

RISC-V: Init and Halt Code

This contains the various __init C functions, the initial assembly kernel entry point, and the code to reset the system. When a file was init-related this patch contains the entire file. Signed-off-by: Palmer Dabbelt
