2019-06-03sh: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-16/+4
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2016-12-24Replace <asm/uaccess.h> with <linux/uaccess.h> globallyLinus Torvalds1-1/+1
This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>' sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

2014-03-04sh: prefix sh-specific "CCR" and "CCR2" by "SH_"Geert Uytterhoeven1-1/+1
Commit bcf24e1daa94 ("mmc: omap_hsmmc: use the generic config for omap2plus devices"), enabled the build for other platforms for compile testing. sh-allmodconfig now fails with: include/linux/omap-dma.h:171:8: error: expected identifier before numeric constant make[4]: *** [drivers/mmc/host/omap_hsmmc.o] Error 1 This happens because SuperH #defines "CCR", which is one of the enum values in include/linux/omap-dma.h. There's a similar issue with "CCR2" on sh2a. As "CCR" and "CCR2" are too generic names for global #defines, prefix them with "SH_" to fix this.

2011-06-06sh: fix wrong icache/dcache address-array start addr in cache-debugfs.Srinivas KANDAGATLA1-20/+5
This patch fixes a icache/dcache address-array start address while dumping its entires in debugfs. Perviously the code was attempting to remember the address in static variable, which is no more required for debugfs, as the function can be executed in one pass. Without this patch the start address ends up in wrong place and the /sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

2010-09-24sh: provide generic arch_debugfs_dir.Paul Mundt1-8/+2
While sh previously had its own debugfs root, there now exists a common arch_debugfs_dir prototype, so we switch everything over to that. Presumably once more architectures start making use of this we'll be able to just kill off the stub kdebugfs wrapper. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-26sh: Mass ctrl_in/outX to __raw_read/writeX conversion.Paul Mundt1-2/+2
The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.

2010-01-21sh: Kill off the special uncached section and fixmap.Paul Mundt1-2/+1
Now that cached_to_uncached works as advertized in 32-bit mode and we're never going to be able to map < 16MB anyways, there's no need for the special uncached section. Kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-20Fix debugfs_create_file's error checking method for arch/sh/mm/Zhaolei1-0/+6

2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy1-4/+5
Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

2007-02-13sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt1-2/+2
There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven1-1/+1
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.
