tile/ptrace: Preserve previous registers for short regset write

2017-01-06T20:14:08+00:00

Ensure that if userspace supplies insufficient data to PTRACE_SETREGSET to fill all the registers, the thread's old registers are preserved. Cc: stable@vger.kernel.org Signed-off-by: Dave Martin Signed-off-by: Chris Metcalf

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

tile: use __ro_after_init instead of tile-specific __write_once

2016-12-16T20:32:29+00:00

The semantics of the old tile __write_once are the same as the newer generic __ro_after_init, so rename them all and get rid of the tile-specific version. This does not enable actual support for __ro_after_init, which had been dropped from the tile architecture before the initial upstreaming was done, since we had at that time switched to using 16MB huge pages to map the kernel.

tile: migrate exception table users off module.h and onto extable.h

2016-12-16T20:32:29+00:00

These files were only including module.h for exception table related functions. We've now separated that content out into its own file "extable.h" so now move over to that and avoid all the extra header content in module.h that we don't really need to compile these files.

tile: remove #pragma unroll from finv_buffer_remote()

2016-12-16T20:32:29+00:00

This directive was put in the kernel source before the "pragma unroll" support for tilegx gcc was upstreamed. Remove it for now, and we can put it back later if/when the compiler support is upstreamed. This avoids a warning when building the kernel. This routine is not on a hot path in any case, so the extra optimization here was mostly just for its own sake. Signed-off-by: Chris Metcalf

tile-module: Rename jump labels in module_alloc()

2016-12-16T20:32:29+00:00

Adjust jump labels according to the current Linux coding style convention. Signed-off-by: Markus Elfring Signed-off-by: Chris Metcalf

tile-module: Use kmalloc_array() in module_alloc()

2016-12-16T20:32:29+00:00

* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.

arch/tile: add option to skip DMA sync as a part of map and unmap

2016-12-15T00:04:08+00:00

This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to avoid invoking cache line invalidation if the driver will just handle it via a sync_for_cpu or sync_for_device call.
