2011-10-24MIPS: perf: Add support for 64-bit perf counters.David Daney
The hard coded constants are moved to struct mips_pmu. All counter register access move to the read_counter and write_counter function pointers, which are set to either 32-bit or 64-bit access methods at initialization time. Many of the function pointers in struct mips_pmu were not needed as there was only a single implementation, these were removed. I couldn't figure out what made struct cpu_hw_events.msbs[] at all useful, so I removed it too. Some functions and other declarations were reordered to reduce the need for forward declarations.

The contents of arch/mips/kernel/perf_event.c and arch/mips/kernel/perf_event_mipsxx.c were divided in a seemingly ad hoc manner, with the first including the second. I moved all the hardware counter support code to perf_event_mipsxx.c and removed the gating #ifdefs to the Kconfig and Makefile. Now perf_event.c contains only the callchain support, everything else is in perf_event_mipsxx.c There are no code changes, only moving of functions from one file to the other, or removing empty unneeded functions.

2011-10-20Revert "MIPS: LD/SD o32 macro GAS fix update"Ralf Baechle
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.

2011-09-21MIPS: No branches in delay slots for huge pages in handle_tlblDavid Daney
For the case PM_DEFAULT_MASK == 0, we were placing a branch in the delay slot of another branch. This leads to undefined behavior.

Current Octeon systems do in fact have holes in their memory zones. We need to select HOLES_IN_ZONE. If we do not, some memory configurations will result in crashes at boot time like this: . . .

2011-09-21MIPS: PM: Use struct syscore_ops instead of sysdevs for PM (v2)Rafael J. Wysocki
Convert some MIPS architecture's code to using struct syscore_ops objects for power management instead of sysdev classes and sysdevs. This simplifies the code and reduces the kernel's memory footprint. It also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J.

2011-09-21MIPS: Compat: Use 32-bit wrapper for compat_sys_futex.Yong Zhang
We can't trust userspace to pass signed-extend arguments. Not correctly sign-extended arguments to futex-wait result in architecturally undefined operation of 32-bit arithmetic instructions. For example, if 'val' is too big and bit-31 is 1, the caller may enter endless loop at: futex_wait_setup() { ... if (uval != val) { queue_unlock(q, *hb); ret = -EWOULDBLOCK; ... } Signed-off-by: Yong Zhang <yong.zhang@windriver.com> To: linux-mips@linux-mips.org To: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/2714/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-09-21MIPS: Do not use EXTRA_CFLAGSArnaud Lacombe
Usage of these flags has been deprecated for nearly 4 years by: commit f77bf01425b11947eeb3b5b54685212c302741b8 Author: Sam Ravnborg <sam@neptun.(none)> Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

2011-09-21MIPS: Alchemy: DB1200: Disable cascade IRQ in handlerManuel Lauss
Disable the cascade IRQ in the cascade handler. This is required to get the DB1300 working, and also gets rid of all spurious interrupts previously observed on the DB1200; so Config[OD] can be disabled again for better performance.
