2023-12-10mips: add missing declarations for trap handlersArnd Bergmann
These exception handlers are all called from assembly code, so they don't normally need a declaration, but without one we now get warnings: arch/mips/mm/fault.c:323:17: error: no previous prototype for 'do_page_fault' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:447:17: error: no previous prototype for 'do_be' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:752:17: error: no previous prototype for 'do_ov' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:874:17: error: no previous prototype for 'do_fpe' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1027:17: error: no previous prototype for 'do_bp' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1114:17: error: no previous prototype for 'do_tr' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1151:17: error: no previous prototype for 'do_ri' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1402:17: error: no previous prototype for 'do_cpu' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1507:17: error: no previous prototype for 'do_msa_fpe' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1527:17: error: no previous prototype for 'do_msa' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1548:17: error: no previous prototype for 'do_mdmx' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1560:17: error: no previous prototype for 'do_watch' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1587:17: error: no previous prototype for 'do_mcheck' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1612:17: error: no previous prototype for 'do_mt' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1648:17: error: no previous prototype for 'do_dsp' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1656:17: error: no previous prototype for 'do_reserved' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1832:17: error: no previous prototype for 'cache_parity_error' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1880:17: error: no previous prototype for 'do_ftlb' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1909:17: error: no previous prototype for 'do_gsexc' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1944:6: error: no previous prototype for 'ejtag_exception_handler' [-Werror=missing-prototypes] arch/mips/kernel/traps.c:1989:17: error: no previous prototype for 'nmi_exception_handler' [-Werror=missing-prototypes] arch/mips/kernel/unaligned.c:1516:17: error: no previous prototype for 'do_ade' [-Werror=missing-prototypes] Link: https://lkml.kernel.org/r/20231204115710.2247097-4-arnd@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Stephen Rothwell <sfr@rothwell.id.au> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2022-02-22MIPS: remove asm/war.hThomas Bogendoerfer
The major part for workaround handling has already moved to config options. This change replaces the remaining defines by already available config options and gets rid of war.h Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

2019-10-07MIPS: r4k-bugs64: Drop CONFIG_CPU_MIPSR6 checksPaul Burton
The r4k-bugs64 code will no longer be built for MIPSr6 kernel configurations, so there's no need to perform checks for MIPSr6 within the code. Drop those redundant checks. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: linux-mips@vger.kernel.org
2019-10-07MIPS: r4k-bugs64: Limit R4k bug checks to affected systemsPaul Burton
Only build the checks for R4k errata workarounds if we expect that the kernel might actually run on a system with an R4k CPU - ie. CONFIG_SYS_HAS_CPU_R4X00=y & we're targeting a pre-MIPSr1 ISA revision. Rename cpu-bugs64.c to r4k-bugs64.c to indicate the fact that the code is specific to R4k CPUs.
