2011-11-10MIPS: ASID conflict after CPU hotplugMaksim Rayskiy
I am running SMP Linux 2.6.37-rc1 on BMIPS5000 (single core dual thread) and observe some abnormalities when doing system suspend/resume which I narrowed down to cpu hotplugging. The suspend brings the second thread processor down and then restarts it, after which I see memory corruption in userspace. I started digging and found out that problem occurs because while doing execve() the child process is getting the same ASID as the parent, which obviously corrupts parent's address space. Further digging showed that activate_mm() calls get_new_mmu_context() to get a new ASID, but at this time ASID field in entryHi is 1, and asid_cache(cpu) is 0x100 (it was just reset to ASID_FIRST_VERSION when the secondary TP was booting). So, get_new_mmu_context() increments the asid_cache(cpu) value to 0x101, and thus puts 0x01 into entryHi. The result - ASID field does not get changed as it was supposed to. My solution is very simple - do not reset asid_cache(cpu) on TP warm restart. Patchwork: https://patchwork.linux-mips.org/patch/1797/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2011-11-08MIPS: Kernel hangs occasionally during boot.Al Cooper
The Kernel hangs occasionally during boot after "Calibrating delay loop..". This is caused by the c0_compare_int_usable() routine in cevt-r4k.c returning false which causes the system to disable the timer and hang later. The false return happens because the routine is using a series of four calls to irq_disable_hazard() as a delay while it waits for the timer changes to propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the series of irq_disable_hazard() calls turn into ehb instructions and can take as little as a few clock ticks for all 4 instructions. This is not enough of a delay, so the routine thinks the timer is not working. This fix uses up to a max number of cycle counter ticks for the delay and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the hazard condition between cp0 writes and cp0 reads.

2011-10-28compat: sync compat_stats with statfs.Eric W. Biederman
This was found by inspection while tracking a similar bug in compat_statfs64, that has been fixed in mainline since decemeber. - This fixes a bug where not all of the f_spare fields were cleared on mips and s390. - Add the f_flags field to struct compat_statfs - Copy f_flags to userspace in case someone cares. - Use __clear_user to copy the f_spare field to userspace to ensure that all of the elements of f_spare are cleared. On some architectures f_spare is has 5 ints and on some architectures f_spare only has 4 ints. Which makes the previous technique of clearing each int individually broken. I don't expect anyone actually uses the old statfs system call anymore but if they do let them benefit from having the compat and the native version working the same. Signed-off-by: Eric W.

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.
