* MIPS, IDE: Alchem, au1xxx-ide: Remove pb1200/db1200 header depManuel Lauss2011-10-246-24/+40
| | | | | | | | | | | | | | | | au1xxx-ide uses defines from the pb1200/db1200 headers: get DBDMA ID through platform resource information, hardcode register spacing. The only 2 users of this driver (and the only boards it can really work on realiably) use the same register layout.

| | | | | | | | | | | | | | | | Alchemy chips have one or more registers which control access to the usb blocks as well as PHY configuration.

| | | | | | | | | | | | | | | This patch removes the last hardcoded base address from the au1000_eth driver.

| | | | | | | | | | | | | | This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) / 82b89152f00f7ad17844d5614d5011e8d7944ac9 (kernel.org) [MIPS: LD/SD o32 macro GAS fix update]. Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now.

* Avoid using variable-length arrays in kernel/sys.cLinus Torvalds2011-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | The size is always valid, but variable-length arrays generate worse code for no good reason (unless the function happens to be inlined and the compiler sees the length for the simple constant it is). Also, there seems to be some code generation problem on POWER, where Henrik Bakken reports that register r28 can get corrupted under some subtle circumstances (interrupt happening at the wrong time?). That all indicates some seriously broken compiler issues, but since variable length arrays are bad regardless, there's little point in trying to chase it down. "Just don't do that, then".

This caused "sensors" and possibly other monitoring tools to report these sensors as "transistor" instead of "thermal diode". Furthermore, diode subtype selection (CPU vs. external) is only supported by the original W83627EHF/EHG. All later models only support CPU diode type, and some (NCT6776F) don't even have the register in question so we should avoid reading from it.

Revert back to use a kthread per filesystem which fixes all the above issues at the cost of having a task struct and stack around for each mounted filesystem.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 32-bit TILEPro support uses some #defines in <asm/atomic_32.h> for atomic support routines in assembly. To make this more explicit, I've turned those includes into includes of <asm/atomic_32.h>, which should hopefully make it clear that they shouldn't be bombed into <linux/atomic.h> in any cleanups.

Linus suggested in https://lkml.org/lkml/2011/8/9/376 to default to vsyscall=native for now, this patch implements that.

* | | | x86, mrst: use a temporary variable for SFI irqMika Westerberg2011-10-141-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SFI tables reside in RAM and should not be modified once they are written. Current code went to set pentry->irq to zero which causes subsequent reads to fail with invalid SFI table checksum. This will break kexec as the second kernel fails to validate SFI tables. To fix this we use temporary variable for irq number. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Kirill A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the 16 bit access to mscan registers there's too much data copied to the zero initialized CAN frame when having an odd number of bytes to copy. This patch ensures that only the requested bytes are copied by using an 8 bit access for the remaining byte.

In x86, that meant it was being swapped to BE and written to the descriptor and to memory, depending on the case of blue frame support or writing to doorbell register. On PPC, this meant it was being swapped to LE and then swapped back to BE while writing to the register. But in the blue frame case, it was being written as LE to the descriptor. The fix is not to swap doorbell unconditionally, write it to the register as BE and convert it to BE when writing it to the descriptor.
