The check for secs being less than zero is redundant for two reasons. Firstly, secs is unsigned so the check is always going to be false. Secondly, if secs was signed the proceeding calculation of secs is never going to be negative. Hence we can remove this redundant check and day and secs re-adjustment. Detected by static analysis with smatch: arcmsr_set_iop_datetime() warn: unsigned 'secs' is never less than zero.

This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

This mechanically converts all remaining cases of ancient open-coded timer setup with the old setup_timer() API, which is the first step in timer conversions. This has no behavioral changes, since it ultimately just changes the order of assignment to fields of struct timer_list when finding variations of: init_timer(&t); f.function = timer_callback; t.data = timer_callback_arg; to be converted into: setup_timer(&t, timer_callback, timer_callback_arg); The conversion is done with the following Coccinelle script, which is an improved version of scripts/cocci/api/setup_timer.cocci, in the following ways: - assignments-before-init_timer() cases - limit the .data case removal to the specific struct timer_list instance - handling calls by dereference (timer->field vs timer.field) spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/setup_timer.cocci @fix_address_of@ expression e; @@ init_timer( -&(e) +&e , ...) // Match the common cases first to avoid Coccinelle parsing loops with // "... when" clauses. @match_immediate_function_data_after_init_timer@ expression e, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) @match_immediate_function_data_before_init_timer@ expression e, func, da; @@ ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @match_function_and_data_after_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ... when != func = e2 when != da = e3 ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) @match_function_and_data_before_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) ... when != func = e2 when != da = e3 -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @r1 exists@ expression t; identifier f; position p; @@ f(...) { ... when any init_timer@p(\(&t\|t\)) ... when any } @r2 exists@ expression r1.t; identifier g != r1.f; expression e8; @@ g(...) { ... when any \(t.data\|t->data\) = e8 ... when any } // It is dangerous to use setup_timer if data field is initialized // in another function. @script:python depends on r2@ p << r1.p; @@ cocci.include_match(False) @r3@ expression r1.t, func, e7; position r1.p; @@ ( -init_timer@p(&t); +setup_timer(&t, func, 0UL); ... when != func = e7 -t.function = func; | -t.function = func; ... when != func = e7 -init_timer@p(&t); +setup_timer(&t, func, 0UL); | -init_timer@p(t); +setup_timer(t, func, 0UL); ... when != func = e7 -t->function = func; | -t->function = func; ... when != func = e7 -init_timer@p(t); +setup_timer(t, func, 0UL); ) Signed-off-by: NKees Cook <keescook@chromium.org>

Switch the arcmsr driver to use pci_alloc_irq_vectors. We need to two calls to pci_alloc_irq_vectors as arcmsr only supports multiple MSI-X vectors, but not multiple MSI vectors. Otherwise this cleans up a lot of cruft and allows to use a common request_irq loop for irq types, which happens to only iterate over a single line in the non MSI-X case.

Quoting Arnd: I was thinking the opposite approach and basically removing all uses of IORESOURCE_CACHEABLE from the kernel. There are only a handful of them.and we can probably replace them all with hardcoded ioremap_cached() calls in the cases they are actually useful. All existing usages of IORESOURCE_CACHEABLE call ioremap() instead of ioremap_nocache() if the resource is cacheable, however ioremap() is uncached by default. Clearly none of the existing usages care about the cacheability. Particularly devm_ioremap_resource() never worked as advertised since it always fell back to plain ioremap(). Clean this up as the new direction we want is to convert ioremap_<type>() usages to memremap(..., flags).

Drop the now unused reason argument from the ->change_queue_depth method. Also add a return value to scsi_adjust_queue_depth, and rename it to scsi_change_queue_depth now that it can be used as the default ->change_queue_depth implementation.

Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.
