2020-06-01sh: remove sh5 supportArnd Bergmann1-212/+0
sh5 never became a product and has probably never really worked. Remove it by recursively deleting all associated Kconfig options and all corresponding files.

2018-10-31treewide: remove current_text_addrNick Desaulniers1-15/+0
Prefer _THIS_IP_ defined in linux/kernel.h. Most definitions of current_text_addr were the same as _THIS_IP_, but a few archs had inline assembly instead. This patch removes the final call site of current_text_addr, making all of the definitions dead code.

2017-09-22arch: remove unused *_segments() macros/functionsTobias Klauser1-4/+0
Some architectures define the no-op macros/functions copy_segments, release_segments and forget_segments. These are used nowhere in the tree, so removed them.

2013-11-13sh: move fpu_counter into ARCH specific thread_structVineet Gupta1-0/+10
Only a couple of arches (sh/x86) use fpu_counter in task_struct so it can be moved out into ARCH specific thread_struct, reducing the size of task_struct for other arches.

b4265f12340f809447b9a48055e88c444b480c89 (mm: use vm_unmapped_area() on sh architecture) broke sh boot. This patch define TASK_UNMAPPED_BASE as a page aligned constant to solve this issue.

2012-05-23Merge branch 'x86-fpu-for-linus' of ↵Linus Torvalds1-1/+0
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull fpu state cleanups from Ingo Molnar: "This tree streamlines further aspects of FPU handling by eliminating the prepare_to_copy() complication and moving that logic to arch_dup_task_struct(). It also fixes the FPU dumps in threaded core dumps, removes and old (and now invalid) assumption plus micro-optimizes the exit path by avoiding an FPU save for dead tasks." Fixed up trivial add-add conflict in arch/sh/kernel/process.c that came in because we now do the FPU handling in arch_dup_task_struct() rather than the legacy (and now gone) prepare_to_copy(). * 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, fpu: drop the fpu state during thread exit x86, xsave: remove thread_has_fpu() bug check in __sanitize_i387_state() coredump: ensure the fpu state is flushed for proper multi-threaded core dump fork: move the real prepare_to_copy() users to arch_dup_task_struct()
2012-05-16fork: move the real prepare_to_copy() users to arch_dup_task_struct()Suresh Siddha1-1/+0
Historical prepare_to_copy() is mostly a no-op, duplicated for majority of the architectures and the rest following the x86 model of flushing the extended register state like fpu there. Remove it and use the arch_dup_task_struct() instead.

2012-04-19sh64: Kill off unused trap_no/error_code from thread_struct.Paul Mundt1-3/+0
While the trap number and error code are passed around for debugging purposes, this occurs wholly independently of the thread struct values. These values were never part of the sigcontext ABI and are thus never passed anywhere, so we can just kill them off across the board. Signed-off-by: Paul Mundt <[email protected]>
2011-06-14sh, exec: remove redundant set_fs(USER_DS)Mathias Krause1-1/+0
The address limit is already set in flush_old_exec() so those calls to set_fs(USER_DS) are redundant. Signed-off-by: Mathias Krause <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-06-14sh: Add kprobe-based event tracer.Paul Mundt1-3/+0
This follows the x86/ppc changes for kprobe-based event tracing on sh. While kprobes is only supported on 32-bit sh, we provide the API for HAVE_REGS_AND_STACK_ACCESS_API for both 32 and 64-bit. Signed-off-by: Paul Mundt <[email protected]>
2010-02-23sh: wire up SET/GET_UNALIGN_CTL.Paul Mundt1-0/+5
This hooks up the SET/GET_UNALIGN_CTL knobs cribbing the bulk of it from the PPC and ia64 implementations. The thread flags happen to be the logical inverse of what the global fault mode is set to, so this works out pretty cleanly. By default the global fault mode is used, with tasks now being able to override their own settings via prctl(). Signed-off-by: Paul Mundt <[email protected]>
2010-01-19sh64: Fix up the build for the thread_xstate changes.Paul Mundt1-9/+9
