Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

The loop condition is fragile: we compare an unsigned value to zero, and then decrement it by something larger than one in the loop. All the callers should be passing in appropriately aligned buffer lengths, but it's better to just not rely on it, and have some appropriate defensive loop limits.

The UV BIOS has moved the location of some of their pointers to the "partition reserved page" from memory into a uv hub MMR. The GRU does not support bcopy operations from MMR space so we need to special case the MMR addresses using VLOAD operations. Additionally, the BIOS call for registering a message queue watchlist has removed the 'blade' value and eliminated the structure that was being passed in. This is also reflected in this patch.

The UV BIOS has been updated to implement some of our interface functionality differently than originally expected. These patches update the kernel to the bios implementation and include a few minor bug fixes which prevent us from doing significant testing on real hardware. This patch: For SGI UV systems, translate from a global physical address back to a socket physical address. This does nothing to ensure the socket physical address is actually addressable by the kernel. That is the responsibility of the user of the function.

由 Oleg Nesterov 提交于
Suggested by Roland. Unlike powepc, x86 always calls tracehook_report_syscall_exit(step) with step = 0, and sends the trap by hand. This results in unnecessary SIGTRAP when PTRACE_SINGLESTEP follows the syscall-exit stop. Change syscall_trace_leave() to pass the correct "step" argument to tracehook and remove the send_sigtrap() logic.

The instruction attribute table generator fails when run by mawk or original-awk: $ mawk -f arch/x86/tools/gen-insn-attr-x86.awk \ arch/x86/lib/x86-opcode-map.txt > /dev/null Semantic error at 240: Second IMM error $ echo $? 1 Line 240 contains "c8: ENTER Iw,Ib", which indicates that this instruction has two immediate operands, the second of which is one byte. The script loops through the immediate operands using a for loop. Unfortunately, there is no guarantee in awk that a for (variable in array) loop will return the indices in increasing order. Internally, both original-awk and mawk iterate over a hash table for this purpose, and both implementations happen to produce the index 2 before 1. The supposed second immediate operand is more than one byte wide, producing the error. So loop over the indices in increasing order instead. As a side-effect, with mawk this means the silly two-entry hash table never has to be built.

This driver was merged before the ep93xx core support was added for the keypad clock and acquiring/releasing the necessary gpio's. Now that the proper support is in the ep93xx core this driver needs to be updated to work correctly. Summary of changes: 1) Remove some unused members from the platform data. 2) Remove the custom KEY macro and use the ones available in <linux/input/matrix_keypad.h> 3) Remove the keypad_{readl/writel} macros and just use __raw_{readl/writel} directly. 4) Update the clk_set_rate() call to work with the core support. 5) Cleanup the probe routine and remove some unneeded messages. 6) Use the ep93xx core functions to acquire and release the gpio's. 7) Fix the clk_get() call to get the keypad clock.
