commit a09d431f344d854e4fe9cfac44f78cb8202f3eb7 upstream. When the force changes went in back in 3.3.0, we ended up returning disconnected in the !force case, and the connected in when forced, as it hit the hardcoded check. Fix it so all exits go via the hardcoded check and stop spurious modesets on platforms with hardcoded EDIDs.

commit 16a5e32b83fd946312b9b13590c75d20c95c5202 upstream. My rv515 card is very flaky with msi enabled. Every so often it loses a rearm and never comes back, manually banging the rearm brings it back.

commit e36325071832f1ba96ac54fb8ba1459f08b05dd8 upstream. The check of the encoder type in the commit [e00e8b5e: drm/radeon/kms: fix analog load detection on DVI-I connectors] is obviously wrong, and it's the culprit of the regression on my workstation with DVI-analog connection resulting in the blank output. Fixed the typo now.

commit afbaa90b80b1ec66e5137cc3824746bfdf559b18 upstream. If a bitmap is added while the array is active, it is possible for bitmap_daemon_work to run while the bitmap is being initialised. This is particularly a problem if bitmap_daemon_work sees bitmap->filemap as non-NULL before it has been filled in properly. So hold bitmap_info.mutex while filling in ->filemap to prevent problems. This patch is suitable for any -stable kernel, though it might not apply cleanly before about 3.1.

commit c43f1508686e8e4746012bf87995085eeb0f5307 upstream.
Currently, executing suspend/hibernation,
memory access violation occurs.
In pch_dma_save_regs() called by suspend(),
you can see the following code.
static void pch_dma_save_regs(struct pch_dma *pd)
{
snip...
list_for_each_entry_safe(chan, _c, &pd->dma.channels, device_node) {
pd_chan = to_pd_chan(chan);
pd->ch_regs[i].dev_addr = channel_readl(pd_chan, DEV_ADDR);
pd->ch_regs[i].mem_addr = channel_readl(pd_chan, MEM_ADDR);
pd->ch_regs[i].size = channel_readl(pd_chan, SIZE);
pd->ch_regs[i].next = channel_readl(pd_chan, NEXT);
i++;
}
}
Max loop count is 12 defined at pci_table.
So, this caused memory access violation.
This patch fixes the issue
- Modify array size (MAX_CHAN_NR)

commit 0b052f4a088ddc47a5da23dd733522241314cfb4 upstream. Currently, Mode-Control register is accessed by read-modify-write. According to DMA hardware specifications datasheet, prohibits this method. Because this register resets to 0 by DMA HW after DMA transfer completes. Thus, current read-modify-write processing can cause unexpected behavior. The datasheet says in case of writing Mode-Control register, set the value for only target channel, the others must set '11b'. e.g. Set DMA0=01b DMA11=10b CTL0=33333331h CTL2=00002333h NOTE: CTL0 includes DMA0~7 Mode-Control register. CTL2 includes DMA8~11 Mode-Control register. This patch modifies the issue.
