sh: remove spurious circular inclusion from asm/smp.h

2020-09-14T01:11:40+00:00

Commit 0cd39f4600ed4de8 added inclusion of smp.h to lockdep.h, creating a circular include dependency where arch/sh's asm/smp.h in turn includes spinlock.h which depends on lockdep.h. Since our asm/smp.h does not actually need spinlock.h, just remove it. Fixes: 0cd39f4600ed4de8 ("locking/seqlock, headers: Untangle the spaghetti monster") Tested-by: Rob Landley Signed-off-by: Rich Felker

sh: use generic strncpy()

2020-08-15T02:56:57+00:00

Current SH will get below warning at strncpy() In file included from ${LINUX}/arch/sh/include/asm/string.h:3, from ${LINUX}/include/linux/string.h:20, from ${LINUX}/include/linux/bitmap.h:9, from ${LINUX}/include/linux/nodemask.h:95, from ${LINUX}/include/linux/mmzone.h:17, from ${LINUX}/include/linux/gfp.h:6, from ${LINUX}/innclude/linux/slab.h:15, from ${LINUX}/linux/drivers/mmc/host/vub300.c:38: ${LINUX}/drivers/mmc/host/vub300.c: In function 'new_system_port_status': ${LINUX}/arch/sh/include/asm/string_32.h:51:42: warning: array subscript\ 80 is above array bounds of 'char[26]' [-Warray-bounds] : "0" (__dest), "1" (__src), "r" (__src+__n) ~~~~~^~~~ In general, strncpy() should behave like below. char dest[10]; char *src = "12345"; strncpy(dest, src, 10); // dest = {'1', '2', '3', '4', '5', '\0','\0','\0','\0','\0'} But, current SH strnpy() has 2 issues. 1st is it will access to out-of-memory (= src + 10). 2nd is it needs big fixup for it, and maintenance __asm__ code is difficult. To solve these issues, this patch simply uses generic strncpy() instead of architecture specific one.

sh: bring syscall_set_return_value in line with other architectures

2020-08-15T02:05:20+00:00

Other architectures expect that syscall_set_return_value gets an already negative value as error. That's also what kernel/seccomp.c provides. Signed-off-by: Michael Karcher Tested-by: John Paul Adrian Glaubitz Signed-off-by: Rich Felker

Move the internal implementation details of ioremap out of line, no need to expose any of this to drivers for a slow path API. Signed-off-by: Christoph Hellwig Signed-off-by: Rich Felker

sh: remove KERNEL ifdefs from non-UAPI headers

sh: stacktrace: Remove stacktrace_ops.stack()

2020-08-15T02:05:11+00:00

The SH implementation never called stacktrace_ops.stack(). Presumably this was copied from the x86 implementation. Hence remove the method, and all implementations (most of them are dummies). Signed-off-by: Geert Uytterhoeven Signed-off-by: Rich Felker

Revert "sh: add loglvl to printk_address()"

2020-08-15T02:05:07+00:00

This reverts commit 2deebe4d56d638269a4a728086d64de5734b460a. printk_address() is always used as a continuation of the previous logging, hence it should not include a log level. Signed-off-by: Geert Uytterhoeven Signed-off-by: Rich Felker
