* Driver Core: Make PM operations a const pointerDmitry Torokhov2009-07-244-16/+19
| | | | | | | | They are not supposed to be modified by drivers, so make them const. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
* PM: Remove platform device suspend_late()/resume_early() V2Magnus Damm2009-07-222-38/+0
| | | | | | | | | | | | This is V2 of the platform driver power management late/early callback removal patch. The callbacks ->suspend_late() and ->resume_early() are removed since all in-tree users now have been migrated to dev_pm_ops.

* Driver Core: Add platform device arch data V3Magnus Damm2009-07-228-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow architecture specific data in struct platform_device V3. With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices.

| * vmlinux.lds.h: restructure BSS linker script macrosTim Abbott2009-07-182-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BSS section macros in vmlinux.lds.h currently place the .sbss input section outside the bounds of [__bss_start, __bss_end]. On all architectures except for microblaze that handle both .sbss and __bss_start/__bss_end, this is wrong: the .sbss input section is within the range [__bss_start, __bss_end]. Relatedly, the example code at the top of the file actually has __bss_start/__bss_end defined twice; I believe the right fix here is to define them in the BSS_SECTION macro but not in the BSS macro. Another problem with the current macros is that several architectures have an ALIGN(4) or some other small number just before __bss_stop in their linker scripts. The BSS_SECTION macro currently hardcodes this to 4; while it should really be an argument. It also ignores its sbss_align argument; fix that. mn10300 is the only user at present of any of the macros touched by this patch. It looks like mn10300 actually was incorrectly converted to use the new BSS() macro (the alignment of 4 prior to conversion was a __bss_stop alignment, but the argument to the BSS macro is a start alignment). So fix this as well. I'd like acks from Sam and David on this one. Also CCing Paul, since he has a patch from me which will need to be updated to use BSS_SECTION(0, PAGE_SIZE, 4) once this gets merged.

In the first two cases, the new code returns -ENOMEM, which seems compatible with what is done for similar functions for other architectures. In the last two cases, the new code fails silently, ie just returns, because the function has void return type. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ... when != x == NULL when != x != NULL when != (x || ...)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous unification code put the exception banner behind the "is oops" logic when it should have been printed all the time. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

This work around confuses gdb when the error occurs as the PC will seemed to have moved, so a better long term fix will need to be figured out, but for now this is better than an infinite crash loop.

* | | | | mvsdio: fix handling of partial word at the end of PIO transferNicolas Pitre2009-07-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standard data flow for MMC/SD/SDIO cards requires that the mvsdio controller be set for big endian operation. This is causing problems with buffers which length is not a multiple of 4 bytes as the last partial word doesn't get shifted all the way and stored properly in memory. Let's compensate for this.

Indeed, the second call does not need to save the interrupt state, so it is changed to a simple spin_lock. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression lock1,lock2; expression flags; @@ *spin_lock_irqsave(lock1,flags) ... when != flags *spin_lock_irqsave(lock2,flags) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Since 2.6.30 (commit 4995f8ef9d3aac72745e12419d7fbaa8d01b1d81, 'vcs: hook sysfs devices into object lifetime instead of "binding"' to be exact) these devices are no longer created at open() and removed on close(), but controlled by the lifetime of the buffers.
