2009-10-11headers: remove sched.h from interrupt.hAlexey Dobriyan114-0/+114
After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

For AGP to work unmapped access must cover VRAM & AGP as AGP is treated like VRAM by the GPU (ie physical address). This patch properly setup the virtual memory system aperture to cover AGP if AGP is enabled. It seems that there is memory corruption after resume when using AGP (RV770 seems unaffected thought).

We still need to find out what is wrong when AGP fails but at least user have a lot of more chances to get a working configuration with acceleration.

In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id is destroyed") a call to the provider's reject handler was added to destroy_cm_id() to fix a provider endpoint leak. This call needs to be done with interrupts enabled. So unlock and relock around this call. This is safe because: 1) the provider will do nothing with this endpoint until the iwcm either accepts or rejects. 2) the lock is only released after the iwcm state is changed, so an errant iwcm app that is destroying -and- rejecting the connection concurrently will get a failure on one of the calls.

2009-10-07amd64_edac: beef up DRAM error injectionBorislav Petkov2-10/+45
When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask of which bits should be error injected when written to and holds the payload of 16-bit DRAM word when read, respectively.

This patch enabled the ethoc to allocate system memory as buffer when there is no dedicated buffer memory. Some hardware designs may not have dedicated buffer memory such as on chip or off chip SRAM. In this case, only one memory resource is supplied in the platform data instead of two. Then a DMA buffer can be allocated from system memory and used for the transfer.

2009-10-07ethoc: align received packet to make IP header at word boundaryThomas Chou1-0/+4
The packet buffer is allocated at 4 bytes boundary, but the IP header length and version bits is located at byte 14. These bit fields access as 32 bits word and caused exception on processors that do not support unaligned access. The patch adds 2 bytes offset to make the bit fields word aligned.

2009-10-07ethoc: fix buffer address mappingThomas Chou1-4/+3
The pointer address in buffer descriptors is physical address. The pointer that processor used to access packet is virtual address. Though the higher bits of pointer address used by the MAC may be truncated to zero in special case, it is not always true in larger designs.

2009-10-07ethoc: fix typo to compute number of tx descriptorsThomas Chou1-1/+1
It should be max() instead of min(). Use 1/4 of available descriptors for tx, and there should be at least 2 tx descriptors. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: David S. Miller <davem@davemloft.net>
