| | * MIPS: microMIPS: Fix macro naming in micro-assembler.Steven J. Hill2013-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The macros did not properly take into account the ISA that the kernel was being compiled with. A classic MIPS kernel will have the standard 'uasm_i_##op' macro functions with 'MM_uasm_i_##op' macro functions for the microMIPS version. A pure microMIPS kernel will have the standard macros with 'CL_uasm_i_##op' macro functions for the classic version. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
| | * MIPS: Allow ASID size to be determined at boot time.Steven J. Hill2013-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original patch by Ralf Baechle and removed by Harold Koerfgen with commit f67e4ffc79905482c3b9b8c8dd65197bac7eb508. This allows for more generic kernels since the size of the ASID and corresponding masks can be determined at run-time. This patch is also required for the new Aptiv cores and has been tested on Malta and Malta Aptiv platforms.

| | * | | MIPS: Init new mmu_context for each possible CPU to avoid memory corruptionHuacai Chen2013-05-07

To avoid this, we make init_new_context() cover each possible CPU. Scenario: 1, CPU#1 is being offline; 2, On CPU#0, do_fork() call dup_mm() and copy a mm_struct to the child; 3, On CPU#0, dup_mm() call init_new_context(), since CPU#1 is offline and init_new_context() only covers the online CPUs, child has the same asid as its parent on CPU#1 (however, child's asid should be 0); 4, CPU#1 is being online; 5, Now, if both parent and child run on CPU#1, memory corruption (e.g. segfault, bus error, etc.) will occur.

| | * | | MIPS: Build uasm-generated code only once to avoid CPU Hotplug problemHuacai Chen2013-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This and the next patch resolve memory corruption problems while CPU hotplug. Without these patches, memory corruption can triggered easily as below: On a quad-core MIPS platform, use "spawn" of UnixBench-5.1.3 (http:// code.google.com/p/byte-unixbench/) and a CPU hotplug script like this (hotplug.sh): while true; do echo 0 >/sys/devices/system/cpu/cpu1/online echo 0 >/sys/devices/system/cpu/cpu2/online echo 0 >/sys/devices/system/cpu/cpu3/online sleep 1 echo 1 >/sys/devices/system/cpu/cpu1/online echo 1 >/sys/devices/system/cpu/cpu2/online echo 1 >/sys/devices/system/cpu/cpu3/online sleep 1 done Run "hotplug.sh" and then run "spawn 10000", spawn will get segfault after a few minutes. This patch: Currently, clear_page()/copy_page() are generated by Micro-assembler dynamically. But they are unavailable until uasm_resolve_relocs() has finished because jump labels are illegal before that. Since these functions are shared by every CPU, we only call build_clear_page()/ build_copy_page() only once at boot time. Without this patch, programs will get random memory corruption (segmentation fault, bus error, etc.) while CPU Hotplug (e.g. one CPU is using clear_page() while another is generating it in cpu_cache_init()). For similar reasons we modify build_tlb_refill_handler()'s invocation. V2: 1, Rework the code to make CPU#0 can be online/offline. 2, Introduce cpu_has_local_ebase feature since some types of MIPS CPU need a per-CPU tlb_refill_handler().

It left the instances in spinlock.h alone because we knew their use was in fairly small files where .subsection use was fine but of course this was a fragile assumption. LTO breaks this assumption resulting in build errors due to exceeded branch range, so remove further instances of .subsection. The two functions that still use .macro don't currently cause issues however this use is still fragile. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
