2011-07-25MIPS: Add SYNC after cacheflushKevin Cernekee
On processors with deep write buffers, it is likely that many cycles will pass between a CACHE instruction and the time the data actually gets written out to DRAM. Add a SYNC instruction to ensure that the buffers get emptied before the flush functions return. Actual problem seen in the wild: 1) dma_alloc_coherent() allocates cached memory 2) memset() is called to clear the new pages 3) dma_cache_wback_inv() is called to flush the zero data out to memory 4) dma_alloc_coherent() returns an uncached (kseg1) pointer to the freshly allocated pages 5) Caller writes data through the kseg1 pointer 6) Buffered writeback data finally gets flushed out to DRAM 7) Part of caller's data is inexplicably zeroed out This patch adds SYNC between steps 3 and 4, which fixed the problem.

2011-07-25MIPS: pfn_valid() is broken on low memory HIGHMEM systemsKevin Cernekee
pfn_valid() compares the PFN to max_mapnr: __pfn >= min_low_pfn && __pfn < max_mapnr; On HIGHMEM kernels, highend_pfn is used to set the value of max_mapnr. Unfortunately, highend_pfn is left at zero if the system does not actually have enough RAM to reach into the HIGHMEM range. This causes pfn_valid() to always return false, and when debug checks are enabled the kernel will fail catastrophically: Memory: 22432k/32768k available (2249k kernel code, 10336k reserved, 653k data, 1352k init, 0k highmem) NR_IRQS:128 kfree_debugcheck: out of range ptr 81c02900h. Kernel bug detected[#1]: Cpu 0 $ 0 : 00000000 10008400 00000034 00000000 $ 4 : 8003e160 802a0000 8003e160 00000000 $ 8 : 00000000 0000003e 00000747 00000747 ... On such a configuration, max_low_pfn should be used to set max_mapnr. This was seen on 2.6.34.

2011-07-25MIPS: topdown mmap supportJian Peng
This patch introduced topdown mmap support in user process address space allocation policy. Recently, we ran some large applications that use mmap heavily and lead to OOM due to inflexible mmap allocation policy on MIPS32. Since most other major archs supported it for years, it is reasonable to follow the trend and reduce the pain of porting applications. Due to cache aliasing concern, arch_get_unmapped_area_topdown() and other helper functions are implemented in arch/mips/kernel/syscall.c.

2011-07-25drm/radeon: Add a rmb() in IH processingBenjamin Herrenschmidt
We should have a read memory barrier between reading the WPTR from memory and reading ring entries based on that value (ie, we need to ensure both loads are done in order by the CPU). It could be argued that the MMIO reads in r600_ack_irq() might be enough to get that barrier but I prefer keeping an explicit one just in case.

2011-07-25drm/radeon: Do an MMIO read on interrupts when not uisng MSIsBenjamin Herrenschmidt
When not using MSIs, there is no guarantee that DMA from the device has been fully flushed to point where it's visible to the CPU when taking an interrupt. To get this guarantee, we need to perform an MMIO read from the device, which will flush all outstanding DMAs from bridges between the device and the system.

2011-07-25drm/radeon: Writeback endian fixesBenjamin Herrenschmidt
The writeback ring pointer and IH ring pointer are read using le32_to_cpu so we do not want the chip to byteswap them on big-endian. We still want to byteswap the ring itself and the IBs, so we don't touch that but we remove setting of the byteswap bits in CP_RB_RPTR_ADDR and IH_CNTL. In general, for things like that where we control all the accessors easily, we are better off doing the swap in SW rather than HW. Paradoxally, it does keep the code closer to x86 and avoid using poorly tested HW features. I also changed the use of RADEON_ to R600_ in a couple of cases to be more consistent with the surrounding code.

2011-07-25drm/gem: add support for private objectsAlan Cox
These small changes should allow GEM to be used with non shmem objects as well as shmem objects. In the GMA500 case it allows the base framebuffer to appear as a GEM object and thus acquire a handle and work with KMS. For i915 it ought to be trivial to get back the wasted memory but putting the system fb back into stolen RAM and in general I can imagine it allowing the use of GEM and thus KMS with all the older cards that have their framebuffer firmly placed in video RAM.

2011-07-25DRM: clean up and document parsing of video= parameterRolf Eike Beer
The video= parameter of the DRM drivers supports some additional flags that the normal fb drivers do not have. They also allow to limit these flags to specific outputs. Both things were previously undocumented. Also the parsing of the line had some oddities: -A lot of misplaced options were silently ignored or partly rejected instead of stopping the parsing immediately -The 'R' option is documented to follow the 'M' option if specified. It is not documented that 'M' is needed to specify 'R' (also this is the case for normal fb drivers). In fact the code is correct for normal fb drivers but wrong for DRM ones. The old code allowed 'R' only _before_ 'M' (since it parses backwards) and only if 'M' is given at all which is not needed for the DRM drivers. -the margins option ('m') was parsed but later ignored even if the later functions support it. -specifying multiple enable options at the same time did not lead to an error. -specifying something bogus for horizontal resolution (i.e. other things as digits) did not lead to an error but an invalid resolution was used. If any errors are encountered the position of the faulting string is now printed to the user and the complete mode is ignored. This gives much more consistent error behaviour. I also removed some useless assignments and changed the local flag variables to be bool. Signed-off-by: Rolf Eike Beer <eike-kernel@sf-tec.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping to be able to use console in very early boot-up phase. But allocating one TLB just for console caused performance degression that's why ioremaps create new mapping and TLB 63 is automatically released and ready to use.

Several registers weren't saved correctly to the stack. Unaligned expection for system with MMU stores value in ex_tmp_data_loc_X address which is load to registers r3. The next step is to move this value from r3 to a destination register which caused unaligned exception. For several registers this value was directly moved to the register. For example for r28: by "or r28, r0, r3" but register r28 was rewritten when kernel returns from exception handler by value saved on stack. This patch changed r3 saving to the correct address on the stack. For example for r28: by "swi r3, r1, 4 * 28" When kernel returns from the exception handler, correct value is restored.

So use mdelay(20) instead. Fixes this build error: ERROR: "__bad_udelay" [drivers/staging/gma500/psb_gfx.ko] undefined! Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-07-25m68k: Revive reporting of spurious interruptsGeert Uytterhoeven
commit 2502b667ea835ee16685c74b2a0d89ba8afe117a ("Change the m68knommu irq handling to use the generic irq framework.") removed the reporting of spurious interrupts on nommu (68328 and 68360). Bring it back in a generic way, using "atomic_t irq_err_count", as that's what most of the other architectures are using.

2011-07-25m68knommu: Move forward declaration of do_IRQ() from machdep.h to irq.hGeert Uytterhoeven
It is not machine-specific, but common irq infrastructure. Also add the missing asmlinkage, to match its definition. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
