* tile: remove support for TILE64Chris Metcalf2013-09-034-264/+1
| | | | | | | | | | | This chip is no longer being actively developed for (it was superceded by the TILEPro64 in 2008), and in any case the existing compiler and toolchain in the community do not support it. It's unlikely that the kernel works with TILE64 at this point as the configuration has not been tested in years. The support is also awkward as it requires maintaining a significant number of ifdefs. So, just remove it altogether. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

* tile: implement gettimeofday() via vDSOChris Metcalf2013-08-131-1/+2
| | | | | | | | | | | | | This change creates the framework for vDSO calls, makes the existing rt_sigreturn() mechanism use it, and adds a fast gettimeofday(). Now that we need to expose the vDSO address to userspace, we add AT_SYSINFO_EHDR to the set of aux entries provided to userspace. (You can disable any extra vDSO support by booting with vdso=0, but the rt_sigreturn vDSO page will still be provided.) Note that glibc has supported the tile vDSO since release 2.17.

* tile: convert uses of "inv" to "finv"Chris Metcalf2013-07-311-2/+2
| | | | | | | | | | The "inv" (invalidate) instruction is generally less safe than "finv" (flush and invalidate), as it will drop dirty data from the cache. It turns out we have almost no need for "inv" (other than for the older 32-bit architecture in some limited cases), so convert to "finv" where possible and delete the extra "inv" infrastructure.

* tile: Add definition of NR_syscallsSimon Marchi2013-03-211-0/+2
| | | | | | | It is required by the syscall tracepoint mechanism. Signed-off-by: Simon Marchi <simon.marchi@polymtl.ca> Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
* tile: avoid defining INT_MASK macro in <arch/interrupts.h>Chris Metcalf2013-02-042-368/+372
| | | | | | | | | | | | Unfortunately, this name conflicts with a different use of the name in various places through the tree, so don't provide it for the kernel. We preserve it for userspace to avoid breaking any userspace code that relies on this definition. This fixes a number of compile errors for various drivers that are enabled by "allyesconfig".

* arch/tile: clean up tile-specific PTRACE_SETOPTIONSChris Metcalf2012-12-141-1/+1
| | | | | | | | | | | | Use the newer idioms for setting PTRACE_O_xxx and PT_TRACE_xxx flags. Only set/clear tile-specific flags if the generic routine returns success, since otherwise we want to avoid setting any flags at all. Atomically update the ptrace flags with the new values. Eliminate the PT_TRACE_MASK_TILE bitmask and just shift PTRACE_O_MASK_TILE. Add a BUILD_BUG_ON to avoid overlapping with generic bits.

* arch/tile: provide PT_FLAGS_COMPAT value in pt_regsChris Metcalf2012-12-131-0/+6
| | | | | | | | | This flag is set for ptrace GETREGS or PEEKUSER for processes that are COMPAT, i.e. 32-bit. This allows things like strace to easily discover what personality to use, for example. Acked-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
* UAPI: The tile arch uses the generic ucontext.h fileDavid Howells2012-10-171-0/+3
| | | | | | | | | Move the header-y and generic-y lines for ucontext.h from arch/tile/include/asm/Kbuild to the uapi/ Kbuild as the asm-generic variant is used. Signed-off-by: David Howells <dhowells@redhat.com> cc: Chris Metcalf <cmetcalf@tilera.com>
