2008-08-26Ath5k: fix bintval setupJiri Slaby
bintval is set to the initial value at .config_interface which is too late, since it overwrites previously set value from .config. Move the initialization to the .add_interface.

2008-08-26virtio_balloon: fix towards_target when deflating balloonAnthony Liguori
Both v and vb->num_pages are u32 and unsigned int respectively. If v is less than vb->num_pages (and it is, when deflating the balloon), the result is a very large 32-bit number. Since we're returning a s64, instead of getting the same negative number we desire, we get a very large positive number. This handles the case where v < vb->num_pages and ensures we get a small, negative, s64 as the result. Rusty: please push this for 2.6.27-rc4. It's probably appropriate for the stable tree too as it will cause an unexpected OOM when ballooning.

2008-08-25drm/radeon: r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEXNicolai Haehnle
DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

2008-08-23Fix oops in acer_wmi driver (acer_wmi_init)Arjan van de Ven
The acer_wmi driver does a DMI scan for quirks, and then sets flags into the "interface" datastructure for some cases. However, the quirks happen real early before "interface" is per se initialized from NULL. The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the end, when "interface" has it's final value.

2008-08-24mv643xx_eth: enforce multiple-of-8-bytes receive buffer size restrictionLennert Buytenhek
The mv643xx_eth hardware ignores the lower three bits of the buffer size field in receive descriptors, causing the reception of full-sized packets to fail at some MTUs. Fix this by rounding the size of allocated receive buffers up to a multiple of eight bytes. While we are at it, add a bit of extra space to each receive buffer so that we can handle multiple vlan tags on ingress. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-08-24mv643xx_eth: fix NULL pointer dereference in rxq_process()Lennert Buytenhek
When we are low on memory, the assumption that every descriptor in the receive ring will have an skbuff associated with it does not hold. rxq_process() was assuming that if the receive descriptor it is working on is not owned by the hardware, it can safely be processed and handed to the networking stack. But a descriptor in the receive ring not being owned by the hardware can also happen when we are low on memory and did not manage to refill the receive ring fully. This patch changes rxq_process()'s bailout condition from "the first receive descriptor to be processed is owned by the hardware" to "the first receive descriptor to be processed is owned by the hardware OR the number of valid receive descriptors in the ring is zero". Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-08-24mv643xx_eth: fix inconsistent lock semanticsLennert Buytenhek
Nicolas Pitre noted that mv643xx_eth_poll was incorrectly using non-IRQ-safe locks while checking whether to wake up the netdevice's transmit queue. Convert the locking to *_irq() variants, since we are running from softirq context where interrupts are enabled. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-08-24mv643xx_eth: fix double add_timer() on the receive oom timerLennert Buytenhek
Commit 12e4ab79cd828563dc090d2117dc8626b344bc8f ("mv643xx_eth: be more agressive about RX refill") changed the condition for the receive out-of-memory timer to be scheduled from "the receive ring is empty" to "the receive ring is not full". This can lead to a situation where the receive out-of-memory timer is pending because a previous rxq_refill() didn't manage to refill the receive ring entirely as a result of being out of memory, and rxq_refill() is then called again as a side effect of a packet receive interrupt, and that rxq_refill() call then again does not succeed to refill the entire receive ring with fresh empty skbuffs because we are still out of memory, and then tries to call add_timer() on the already scheduled out-of-memory timer. This patch fixes this issue by changing the add_timer() call in rxq_refill() to a mod_timer() call. If the OOM timer was not already scheduled, this will behave as before, whereas if it was already scheduled, this patch will push back its firing time a bit, which is safe because we've (unsuccessfully) attempted to refill the receive ring just before we do this.

2008-08-24mv643xx_eth: fix NAPI 'rotting packet' issueLennert Buytenhek
When a receive interrupt occurs, mv643xx_eth would first process the receive descriptors and then ACK the receive interrupt, instead of the other way round. This would leave a small race window between processing the last receive descriptor and clearing the receive interrupt status in which a new packet could come in, which would then 'rot' in the receive ring until the next receive interrupt would come in. Fix this by ACKing (clearing) the receive interrupt condition before processing the receive descriptors. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

2008-08-22libata: Fix a large collection of DMA mode mismatchesAlan Cox
Dave Müller sent a diff for the pata_oldpiix that highlighted a problem where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while the core code uses 0xFF. This turns out to have other consequences such as code doing >= XFER_UDMA_0 also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect set_dma_mode, although some drivers call back into their own set mode code from other points. Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller <dave.mueller@gmx.ch> -jg] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-08-22ahci: sis controllers actually can do PMPTejun Heo
SIS controllers were blacklisted for PMP as enabling it made device detection fail whether the device was PMP or not - the natural conclusion was the controller chokes on SRST w/ pmp==15. However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.
