There are only two ways to define sg_dma_len(); use sg->dma_length or sg->length. This patch introduces NEED_SG_DMA_LENGTH that enables architectures to choose sg->dma_length or sg->length.

There are two outstanding fashions for archs to implement hardware breakpoints. The first is to separate breakpoint address pattern definition space between data and instruction breakpoints. We then have typically distinct instruction address breakpoint registers and data address breakpoint registers, delivered with separate control registers for data and instruction breakpoints as well. This is the case of PowerPc and ARM for example. The second consists in having merged breakpoint address space definition between data and instruction breakpoint. Address registers can host either instruction or data address and the access mode for the breakpoint is defined in a control register. This is the case of x86 and Super H. This patch adds a new CONFIG_HAVE_MIXED_BREAKPOINTS_REGS config that archs can select if they belong to the second case. Those will have their slot allocation merged for instructions and data breakpoints. The others will have a separate slot tracking between data and instruction breakpoints.

This adds support for hardware-assisted userspace irq masking for special priority levels. Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

IRQ autoprobing hasn't actually worked for us at all since very early in 2.6, but no one seems to have noticed given that none of the drivers that use it see much testing. yenta_socket is the odd one out, and that depends on PCI IRQs which are fixed on all SH platforms anyways. Consequently, turning off autoprobing fixes up crashes triggered by yenta_socket and at least gets it working again on r7785rp. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This rewrites the SH7786 clock framework support completely. It's reworked to provide all of the DIV4 and MSTP function clocks.

Presently ioremap_prot() uses an unsigned long to pass the pgprot value around. This results in the upper half of the pgprot being chomped when using 64-bit pgprots on a 32-bit ABI (X2TLB and SH-5). As the only users of ioremap_prot() are presently legacy parts, this doesn't cause too much of an issue. In the future when the interface is converted to use pgprot_t directly this can be re-enabled for the other parts, too. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

As SH has a very sparse IRQ map by default, all new CPUs and boards benefit from using sparseirq by default. Despite this, there are still a few stragglers (mostly due to using a fixed IRQ range for their FPGA IRQ mappings), and these still need to be converted over one by one. As these are now in the minority, and we do not want to encourage this sort of brain-damage in newer board ports, we force sparseirq on. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

As CPUs are migrated over to more fully-featured clock frameworks of their own and off of the legacy CPG code, they no longer have any real need for defining the PCLK value. The PCLK define in itself is already fairly misleading, as many boards get their input clocks from different sources, making this value fairly arbitrary anyways. Outside of the legacy CPG clock framework, the only place where this value is used is for deriving CLOCK_TICK_RATE, which we set back to the legacy PIT value that it was before the PCLK definitions were added in the first place.

This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

This code was added for some ancient SH-4 solution engines with peculiar boot ROMs that did silly things to the UBC MSTP bits. None of these have been in the wild for years, and these days the clock framework wraps up the MSTP bits, meaning that the UBC code is one of the few interfaces that is stomping MSTP bits underneath the clock framework. At this point the risks far outweigh any benefit this code provided, so just kill it off. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: NStephane Eranian <eranian@google.com> Acked-by: NPeter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: NPaul Mackerras <paulus@samba.org> Reviewed-by: NArjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

So far kernel command line arguments could be passed in by a bootloader or defined as CONFIG_CMDLINE, which completely overwriting the first one. This change allows a developer to declare selected kernel parameters in a kernel configuration (eg. project-specific defconfig), retaining possibility of passing others by a bootloader. The obvious examples of the first type are MTD partition or bigphysarea-like region definitions, while "debug" option or network configuration should be given by a bootloader or a JTAG boot script.
