The lose_fpu() function only disables the FPU in CP0_Status.CU1 if the FPU is in use and MSA isn't enabled. This isn't necessarily a problem because KSTK_STATUS(current), the version of CP0_Status stored on the kernel stack on entry from user mode, does always get updated and gets restored when returning to user mode, but I don't think it was intended, and it is inconsistent with the case of only the FPU being in use. Sometimes leaving the FPU enabled may also mask kernel bugs where FPU operations are executed when the FPU might not be enabled. So lets disable the FPU in the MSA case too.

memsize denotes the amount of RAM we can access from kseg{0,1} and that should be up to 256M. In case the bootloader reports a value higher than that (perhaps reporting all the available RAM) it's best if we fix it ourselves and just warn the user about that. This is usually a problem with the bootloader and/or its environment. [ralf@linux-mips.org: Remove useless parens as suggested bei Sergei.

Commit c1771216 ("MIPS: kernel: unaligned: Handle unaligned accesses for EVA") allowed unaligned accesses to be emulated for EVA. However, when emulating regular load/store unaligned accesses, we need to use the appropriate "address space" instructions for that. Previously, an unaligned load/store instruction in kernel space would have used the corresponding EVA instructions to emulate it which led to segmentation faults because of the address translation that happens with EVA instructions. This is now fixed by using the EVA instruction only when emulating EVA unaligned accesses.

由 Lars Persson 提交于
The lazy cache flushing implemented in the MIPS kernel suffers from a race condition that is exposed by do_set_pte() in mm/memory.c. A pre-condition is a file-system that writes to the page from the CPU in its readpage method and then calls flush_dcache_page(). One example is ubifs. Another pre-condition is that the dcache flush is postponed in __flush_dcache_page(). Upon a page fault for an executable mapping not existing in the page-cache, the following will happen: 1. Write to the page 2. flush_dcache_page 3. flush_icache_page 4. set_pte_at 5. update_mmu_cache (commits the flush of a dcache-dirty page) Between steps 4 and 5 another thread can hit the same page and it will encounter a valid pte. Because the data still is in the L1 dcache the CPU will fetch stale data from L2 into the icache and execute garbage. This fix moves the commit of the cache flush to step 3 to close the race window. It also reduces the amount of flushes on non-executable mappings because we never enter __flush_dcache_page() for non-aliasing CPUs. Regressions can occur in drivers that mistakenly relies on the flush_dcache_page() in get_user_pages() for DMA operations.

This patch rearranges the PTE bits into fixed positions for R2 and later cores. In the past, the TLB handling code did runtime checking of RI/XI and adjusted the shifts and rotates in order to fit the largest PFN value into the PTE. The checking now occurs when building the TLB handler, thus eliminating those checks. These new arrangements also define the largest possible PFN value that can fit in the PTE. HUGE page support is only available for 64-bit cores. Layouts of the PTE bits are now: 64-bit, R1 or earlier: CCC D V G [S H] M A W R P 32-bit, R1 or earler: CCC D V G M A W R P 64-bit, R2 or later: CCC D V G RI/R XI [S H] M A W P 32-bit, R2 or later: CCC D V G RI/R XI M A W P [ralf@linux-mips.org: Fix another build error *rant* *rant*] Signed-off-by: NSteven J.

Currently tty_wait_until_sent may take up to twice as long as the requested timeout while waiting for driver and hardware buffers to drain. Fix this by taking the remaining number of jiffies after waiting for driver buffers to drain into account so that the timeout actually becomes a maximum timeout as it is documented to be. Note that this specifically implies tighter timings when closing a port as a consequence of actually honouring the port closing-wait setting for drivers relying on tty_wait_until_sent_from_close (e.g. via tty_port_close_start).
