2023-11-20sh: bios: Revive earlyprintk supportGeert Uytterhoeven
[ Upstream commit 553f7ac78fbb41b2c93ab9b9d78e42274d27daa9 ] The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK. However, when this protection was added, it was missed that SuperH no longer defines an EARLY_PRINTK config symbol since commit e76fe57447e88916 ("sh: Remove old early serial console code V2"), so BIOS earlyprintk can no longer be used. Fix this by reviving the EARLY_PRINTK config symbol.

2023-07-23sh: dma: Fix DMA channel offset calculationArtur Rojek
[ Upstream commit e82e47584847129a20b8c9f4a1dcde09374fb0e0 ] Various SoCs of the SH3, SH4 and SH4A family, which use this driver, feature a differing number of DMA channels, which can be distributed between up to two DMAC modules. The existing implementation fails to correctly accommodate for all those variations, resulting in wrong channel offset calculations and leading to kernel panics. Rewrite dma_base_addr() in order to properly calculate channel offsets in a DMAC module. Fix dmaor_read_reg() and dmaor_write_reg(), so that the correct DMAC module base is selected for the DMAOR register. Fixes: 7f47c7189b3e8f19 ("sh: dma: More legacy cpu dma chainsawing.")

commit d1155e4132de712a9d3066e2667ceaad39a539c5 upstream. __setup() handlers should return 1 to obsolete_checksetup() in init/main.c to indicate that the boot option has been handled. A return of 0 causes the boot option/value to be listed as an Unknown kernel parameter and added to init's (limited) argument or environment strings. Also, error return codes don't mean anything to obsolete_checksetup() -- only non-zero (usually 1) or zero. So return 1 from nmi_debug_setup(). Fixes: 1e1030dccb10 ("sh: nmi_debug support.")

[ Upstream commit 80f746e2bd0e1da3fdb49a53570e54a1a225faac ] The Store Queue code allocates a bitmap buffer with the size of multiple of sizeof(long) in sq_api_init(). While the buffer size is calculated correctly, the code uses the wrong element size to allocate the buffer which results in the allocated bitmap buffer being too small. Fix this by allocating the buffer with kcalloc() with element size sizeof(long) instead of kzalloc() whose elements size defaults to sizeof(char). Fixes: d7c30c682a27 ("sh: Store Queue API rework.")

2023-03-17sh: define RUNTIME_DISCARD_EXITTom Saeger
commit c1c551bebf928889e7a8fef7415b44f9a64975f4 upstream. sh vmlinux fails to link with GNU ld < 2.40 (likely < 2.36) since commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv"). This is similar to fixes for powerpc and s390: commit 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT"). commit a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36"). $ sh4-linux-gnu-ld --version | head -n1 GNU ld (GNU Binutils for Debian) 2.35.2 $ make ARCH=sh CROSS_COMPILE=sh4-linux-gnu- microdev_defconfig $ make ARCH=sh CROSS_COMPILE=sh4-linux-gnu- `.exit.text' referenced in section `__bug_table' of crypto/algboss.o: defined in discarded section `.exit.text' of crypto/algboss.o `.exit.text' referenced in section `__bug_table' of drivers/char/hw_random/core.o: defined in discarded section `.exit.text' of drivers/char/hw_random/core.o make[2]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1 make[1]: *** [Makefile:1252: vmlinux] Error 2 arch/sh/kernel/vmlinux.lds.S keeps EXIT_TEXT: /* * .exit.text is discarded at runtime, not link time, to deal with * references from __bug_table */ .exit.text : AT(ADDR(.exit.text)) { EXIT_TEXT } However, EXIT_TEXT is thrown away by DISCARD(include/asm-generic/vmlinux.lds.h) because sh does not define RUNTIME_DISCARD_EXIT. GNU ld 2.40 does not have this issue and builds fine.

2023-02-01exit: Add and use make_task_dead.Eric W. Biederman
commit 0e25498f8cd43c1b5aa327f373dd094e9a006da7 upstream. There are two big uses of do_exit. The first is it's design use to be the guts of the exit(2) system call. The second use is to terminate a task after something catastrophic has happened like a NULL pointer in kernel code. Add a function make_task_dead that is initialy exactly the same as do_exit to cover the cases where do_exit is called to handle catastrophic failure. In time this can probably be reduced to just a light wrapper around do_task_dead. For now keep it exactly the same so that there will be no behavioral differences introducing this new concept. Replace all of the uses of do_exit that use it for catastraphic task cleanup with make_task_dead to make it clear what the code is doing. As part of this rename rewind_stack_do_exit rewind_stack_and_make_dead. Signed-off-by: "Eric W.

commit d684e0a52d36f8939eda30a0f31ee235ee4ee741 upstream. Recently, nommu iounmap() was converted from a static inline function to a macro again, basically reverting commit 4580ba4ad2e6b8dd ("sh: Convert iounmap() macros to inline functions"). With -Werror, this leads to build failures like: drivers/iio/adc/xilinx-ams.c: In function `ams_iounmap_ps': drivers/iio/adc/xilinx-ams.c:1195:14: error: unused variable `ams' [-Werror=unused-variable] 1195 | struct ams *ams = data; | ^~~ Fix this by replacing the macros for ioremap() and iounmap() by static inline functions, based on <asm-generic/io.h>.

2021-11-18signal/sh: Use force_sig(SIGKILL) instead of do_group_exit(SIGKILL)Eric W. Biederman
[ Upstream commit ce0ee4e6ac99606f3945f4d47775544edc3f7985 ] Today the sh code allocates memory the first time a process uses the fpu. If that memory allocation fails, kill the affected task with force_sig(SIGKILL) rather than do_group_exit(SIGKILL). Calling do_group_exit from an exception handler can potentially lead to dead locks as do_group_exit is not designed to be called from interrupt context. Instead use force_sig(SIGKILL) to kill the userspace process. Sending signals in general and force_sig in particular has been tested from interrupt context so there should be no problems.

2021-09-03mm: remove flush_kernel_dcache_pageChristoph Hellwig
flush_kernel_dcache_page is a rather confusing interface that implements a subset of flush_dcache_page by not being able to properly handle page cache mapped pages. The only callers left are in the exec code as all other previous callers were incorrect as they could have dealt with page cache pages. Replace the calls to flush_kernel_dcache_page with calls to flush_dcache_page, which for all architectures does either exactly the same thing, can contains one or more of the following: 1) an optimization to defer the cache flush for page cache pages not mapped into userspace 2) additional flushing for mapped page cache pages if cache aliases are possible Link: https://lkml.kernel.org/r/20210712060928.4161649-7-hch@lst.de Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Reviewed-by: Ira Weiny <ira.weiny@intel.com> Cc: Alex Shi <alexs@kernel.org> Cc: Geoff Levand <geoff@infradead.org> Cc: Greentime Hu <green.hu@gmail.com> Cc: Guo Ren <guoren@kernel.org> Cc: Helge Deller <deller@gmx.de> Cc: "James E.J.

Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call
