2007-11-07sh: Kill off __{copy,clear}_user_page().Paul Mundt
Now that copy_to_user_page()/copy_from_user_page() are wired up, we can drop the old __copy_xxx() implementations. Now that the page colouring scheme has changed via kmap_coherent(), we can avoid the flush in these specific helpers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Optimized copy_{to,from}_user_page() for SH-4.Paul Mundt
This moves copy_{to,from}_user_page() out-of-line on SH-4 and converts for the kmap_coherent() API. Based on the MIPS implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Wire up clear_user_highpage().Paul Mundt
With the kmap_coherent() API in place, this is trivial to implement, and lets us avoid the cache flush in certain cases. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off the remaining ST40 cruft.Paul Mundt
The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.

2007-11-07sh: Export __{s,u}divsi3_i4i on all CPUs.Paul Mundt
Currently these are only being exported for CONFIG_CPU_SH4. This invariably breaks when building for an SH-3 that includes multiple targets in multilib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix up kgdb-on-NMI branch target.Paul Mundt
This was all reworked some time ago, the old debug_enter was ripped out with everything going through a debug trap jump table instead. Kill off the debug_enter target and reference kgdb_handle_exception directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: ubc wakeup for SH-4 only.Paul Mundt
SH-4A parts generally don't have any use for this, and it requires an alternate implementation anyways. Leave this as an SH-4 only option, as that's the only place this has been needed in the past. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix compression method when making uImage.Nobuhiro Iwamatsu
When uImage is made by using 'make uImage', zImage is used. If zImage is used, the compression method need not be set. However, it is set for "gzip" for a compression method. I corrected to set "none". Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-11-06[IA64] Disable/re-enable CPE interrupts on AltixRuss Anderson
When the CPE handler encounters too many CPEs (such as a solid single bit memory error), it sets up a polling timer and disables the CPE interrupt (to avoid excessive overhead logging the stream of single bit errors). disable_irq_nosync() calls chip->disable() to provide a chipset specifiec interface for disabling the interrupt. This patch adds the Altix specific support to disable and re-enable the CPE interrupt. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-11-06[IA64] Add gate.lds to list of files ignored by GitPeter Chubb

2007-11-06[IA64] Fix section mismatch in contig.c version of per_cpu_init()Tony Luck
There is a section mismatch when building CONFIG_FLATMEM=y kernels that also have CONFIG_HOTPLUG_CPU=y WARNING: vmlinux.o(.text+0x5a902): Section mismatch: reference to \ .init.text:__alloc_bootmem (between 'per_cpu_init' and 'count_pages') The issue occurs because per_cpu_init() in mm/contig.c is marked __cpuinit (which is #define'd to nothing on a hot plug cpu configuration) call __alloc_bootmem() (which is an __init function). The usage is actually safe because the __alloc_bootmem() is inside an "if (first_time)" test so that the call is only made while it is still legal to do so. But the warning is irritating. Move the allocation to find_memory(). Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-11-05[S390] tod clock: announce clocksource as perfectChristian Borntraeger
The Time of Day clock is the standard time source for s390. It is - monotonic - allows very fast reading - architecture guarantees at least microsecond stepping - available as part of the architecture We should announce the rate of tod as 400 to be in sync with the description found in clocksource.h: "400-499:Perfect The ideal clocksource. A must-use where available." This change will prefer tod over less reliable clock sources.

2007-11-05[S390] Rename "idle_time" attribute to "idle_time_us".Heiko Carstens

2007-11-05[S390] Fix compile on !CONFIG_SMP.Heiko Carstens
Commit fae8b22d3e3e3a3d317a7746493997af02a3f35c "[S390] Add per-cpu idle time / idle count sysfs attributes" causes a link error on !CONFIG_SMP. Fix this by adding some #ifdef's. Real fix would be to cleanup the code since we don't register a cpu on !CONFIG_SMP. But that would be quite a big patch. For the time being this is good enough. arch/s390/kernel/built-in.o: In function `do_monitor_call': (.text+0x50d4): undefined reference to `per_cpu__s390_idle' arch/s390/kernel/built-in.o: In function `cpu_idle': (.text+0x518c): undefined reference to `per_cpu__s390_idle' make: *** [.tmp_vmlinux1] Error 1 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-11-02Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle
The Jazz machines have to use the PIT timer for dyntick and highresolution kernels.
