2010-07-06arch/tile: catch up on various minor cleanups.Chris Metcalf
None of these changes fix any actual bugs, but are just various cleanups that fell out along the way. In particular, some unused #defines and includes are removed, PREFETCH_STRIDE is added (the default is right for our shipping chips, but wrong for our next generation), our tile-specific prefetching code is removed so the (identical) generic prefetching code can be used instead, a comment is fixed to be proper GPL and not just a "paste GPL here" token, a "//" comment is converted to "/* */", etc. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

2010-07-06arch/tile: Miscellaneous cleanup changes.Chris Metcalf
This commit is primarily changes caused by reviewing "sparse" and "checkpatch" output on our sources, so is somewhat noisy, since things like "printk() -> pr_err()" (or whatever) throughout the codebase tend to get tedious to read. Rather than trying to tease apart precisely which things changed due to which type of code review, this commit includes various cleanups in the code: - sparse: Add declarations in headers for globals. - sparse: Fix __user annotations. - sparse: Using gfp_t consistently instead of int. - sparse: removing functions not actually used. - checkpatch: Clean up printk() warnings by using pr_info(), etc.; also avoid partial-line printks except in bootup code. - checkpatch: Use exposed structs rather than typedefs. - checkpatch: Change some C99 comments to C89 comments. In addition, a couple of minor other changes are rolled in to this commit: - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised. - Remove some compat code that is unnecessary when we fully eliminate some of the deprecated syscalls from the generic syscall ABI. - Update the tile_defconfig to reflect current config contents.

2010-07-06arch/tile: Split the icache flush code off to a generic <arch> header.Chris Metcalf
This code is used in other places in our system than in Linux, so to share it we now implement it as an inline function in our low-level <arch> headers, and instantiate it in one file in Linux's arch/tile/lib. The file is now cacheflush.c and is C code rather than the strangely-named and assembler-implemented __invalidate_icache.S.

2010-07-06arch/tile: Fix bug in support for atomic64_xx() ops.Chris Metcalf

2010-07-06arch/tile: Shrink the tile-opcode files considerably.Chris Metcalf
The C file (tile-desc_{32,64}.c) was about 300KB before this change, and is now shrunk down to 100K. The original file included support for BFD in the binutils toolchain, which is not necessary in the kernel; the kernel version only needs to include enough support to enable the single-stepper and backtracer.

2010-07-06arch/tile: Add driver to enable access to the user dynamic network.Chris Metcalf
This network (the "UDN") connects all the cpus on the chip in a wormhole-routed dynamic network. Subrectangles of the chip can be allocated by a "create" ioctl on /dev/hardwall, and then to access the UDN in that rectangle, tasks must perform an "activate" ioctl on that same file object after affinitizing themselves to a single cpu in the region. Sending a wormhole-routed message that tries to leave that subrectangle causes all activated tasks to receive a SIGILL (just as they would if they tried to access the UDN without first activating themselves to a hardwall rectangle). The original submission of this code to LKML had the driver instantiated under /proc/tile/hardwall. Now we just use a character device for this, conventionally /dev/hardwall. Some futures planning for the TILE-Gx chip suggests that we may want to have other types of devices that share the general model of "bind a task to a cpu, then 'activate' a file descriptor on a pseudo-device that gives access to some hardware resource". As such, we are using a device rather than, for example, a syscall, to set up and activate this code. As part of this change, the compat_ptr() declaration was fixed and used to pass the compat_ioctl argument to the normal ioctl. So far we limit compat code to 2GB, so the difference between zero-extend and sign-extend (the latter being correct, eventually) had been overlooked.

2010-07-06arch/tile: Enable more sophisticated IRQ model for 32-bit chips.Chris Metcalf
This model is based on the on-chip interrupt model used by the TILE-Gx next-generation hardware, and interacts much more cleanly with the Linux generic IRQ layer. The change includes modifications to the Tilera hypervisor, which are reflected in the hypervisor headers in arch/tile/include/arch/.

2010-07-06Move list types from <linux/list.h> to <linux/types.h>.Chris Metcalf
This allows a list_head (or hlist_head, etc.) to be used from places that used to be impractical, in particular <asm/processor.h>, which used to cause include file recursion: <linux/list.h> includes <linux/prefetch.h>, which always includes <asm/processor.h> for the prefetch macros, as well as <asm/system.h>, which often includes <asm/processor.h> directly or indirectly. This avoids a lot of painful workaround hackery on the tile architecture, where we use a list_head in the thread_struct to chain together tasks that are activated on a particular hardwall.

2010-07-04ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon
Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same functionality (memory controller), the default way of proping devices doesn't work. So, instead of a per-device probe, all devices should be probed at once. This means that we should block any new attempt of probe, otherwise, it will try to register the same device several times.

Commit 7a772c492fcfffae812ffca78a628e76fa57fe58 has two bugs which made the hotplug problems on my laptop worse instead of better. First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later. The old code never restored PORT_HOTPLUG_EN so this could only happen once, but they new code restores those registers. So just set those bits when we set up the interrupt in the first place.
