2010-04-30MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin1-1/+19
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

2010-04-30MIPS: Loongson 2F: Enable fixups of the latest binutilsWu Zhangjin1-0/+13
With the "Fixups of Loongson2F" patch [1] having been applied to binutils for binutils 2.20.1 we now can use it's time to enable the options provided by the patch to compile the kernel. Without these fixups, the system may hang if the erratum is triggered. For more information on these fixups please refer to the following references.

2010-04-30MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDSWu Zhangjin1-0/+27
As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.

2010-04-30MIPS: Use CKSEG1ADDR for uncached handlerSebastian Andrzej Siewior1-6/+1
"MIPS: Calculate proper ebase value for 64-bit kernels" 9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp. f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit MIPS systems. Before this we were using XKPHYS/cached as ebase and computed the uncached xphsys/unchached address for that area. After that commit ebase became a 32-bit compat address and convert does not work anymore. We now should use CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

2010-04-30MIPS: Check for accesses beyond the end of the PGD.David Daney1-23/+87
For some combinations of PAGE_SIZE and vmbits, it is possible to have userspace access that are beyond what is covered by the PGD, but within vmbits. Such an access would cause the TLB refill handler to load garbage values for PMD and PTE potentially giving userspace access to parts of the physical address space to which it is not entitled. In the TLB refill hot path, we add a single dsrl instruction so we can check if any bits outside of the range covered by the PGD are set. In the vmalloc side we then separate the bad case from the normal vmalloc case and call tlb_do_page_fault_0 if warranted. This slows us down a bit, but has the benefit of yielding deterministic behavior.
