2009-08-05ARM: 5638/1: arch/arm/kernel/signal.c: use correct address space for CRUNCHHartley Sweeten1-2/+2
preserve_crunch_context() calls __copy_to_user() which expects the destination address to be in __user space. setup_sigframe() properly passes the destination address. restore_crunch_context() calls __copy_from_user() which expects the source address to be in __user space. restore_sigframe() properly passes the source address. This fixes {preserve/restore}_crunch_context() to accept the address as __user space and resolves the following sparse warnings: arch/arm/kernel/signal.c:146:31: warning: incorrect type in argument 1 (different address spaces) expected void [noderef] <asn:1>*to got struct crunch_sigframe *frame arch/arm/kernel/signal.c:156:38: warning: incorrect type in argument 2 (different address spaces) expected void const [noderef] <asn:1>*from got struct crunch_sigframe *frame arch/arm/kernel/signal.c:250:48: warning: incorrect type in argument 1 (different address spaces) expected struct crunch_sigframe *frame got struct crunch_sigframe [noderef] <asn:1>*<noident> arch/arm/kernel/signal.c:365:49: warning: incorrect type in argument 1 (different address spaces) expected struct crunch_sigframe *frame got struct crunch_sigframe [noderef] <asn:1>*<noident> Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-07-29pty: avoid forcing 'low_latency' tty flagOGAWA Hirofumi4-2/+15
We really don't want to mark the pty as a low-latency device, because as Alan points out, the ->write method can be called from an IRQ (ppp?), and that means we can't use ->low_latency=1 as we take mutexes in the low_latency case. So rather than using low_latency to force the written data to be pushed to the ldisc handling at 'write()' time, just make the reader side (or the poll function) do the flush when it checks whether there is data to be had. This also fixes the problem with lost data in an emacs compile buffer (bugzilla 13815), and we can thus revert the low_latency pty hack (commit 3a54297478e6578f96fd54bf4daa1751130aca86: "pty: quickfix for the pty ENXIO timing problems").

attributes. For x86 this affected highmem pages only, since they were always kmapped cache-coherent, and this is fixed using kmap_atomic_prot(). For other architectures that may not modify the linear kernel map we resort to vmap() for now, since kmap_atomic_prot() generally uses the linear kernel map for lowmem pages.

2009-07-29drm/radeon/kms: add initial colortiling support.Dave Airlie17-19/+427
This adds new set/get tiling interfaces where the pitch and macro/micro tiling enables can be set. Along with a flag to decide if this object should have a surface when mapped. The only thing we need to allocate with a mapped surface should be the frontbuffer. Note rotate scanout shouldn't require one, and back/depth shouldn't either, though mesa needs some fixes. It fixes the TTM interfaces along Thomas's suggestions, and I've tested the surface stealing code with two X servers and not seen any lockdep issues. I've stopped tiling the fbcon frontbuffer, as I don't see there being any advantage other than testing, I've left the testing commands in there, just flip the fb_tiled to true in radeon_fb.c Open: Can we integrate endian swapping in with this? Future features: texture tiling - need to relocate texture registers TXOFFSET* with tiling info. This also merges Michel's cleanup surfaces regs at init time patch even though it makes sense on its own, this patch really relies on it.

2009-07-28libata: accept late unlocking of HPATejun Heo2-7/+24
On certain configurations, HPA isn't or can't be unlocked during probing but it somehow ends up unlocked afterwards. In the following thread, the problem can be reliably reproduced after resuming from STR. The BIOS turns on HPA during boot but forgets to do it during resume. http://thread.gmane.org/gmane.linux.kernel/858310 This patch updates libata revalidation such that it considers native n_sectors. If the device size has increased to match native n_sectors, it's assumed that HPA has been unlocked involuntarily and the device is recognized as the same one. This should be fairly safe while nicely working around the problem.
