Add huge TLB support to the metag architecture. Signed-off-by: NJames Hogan <james.hogan@imgtec.com>

由 James Hogan 提交于
Meta has instructions for accessing: - bytes - GETB (1 byte) - words - GETW (2 bytes) - doublewords - GETD (4 bytes) - longwords - GETL (8 bytes) All accesses must be aligned. Unaligned accesses can be detected and made to fault on Meta2, however it isn't possible to fix up unaligned writes so we don't bother fixing up reads either. This patch adds metag memory handling code including: - I/O memory (io.h, ioremap.c): Actually any virtual memory can be accessed with these helpers. A part of the non-MMUable address space is used for memory mapped I/O. The ioremap() function is implemented one to one for non-MMUable addresses. - User memory (uaccess.h, usercopy.c): User memory is directly accessible from privileged code. - Kernel memory (maccess.c): probe_kernel_write() needs to be overwridden to use the I/O functions when doing a simple aligned write to non-writecombined memory, otherwise the write may be split by the generic version. Note that due to the fact that a portion of the virtual address space is non-MMUable, and therefore always maps directly to the physical address space, metag specific I/O functions are made available (metag_in32, metag_out32 etc). These cast the address argument to a pointer so that they can be used with raw physical addresses. These accessors are only to be used for accessing fixed core Meta architecture registers in the non-MMU region, and not for any SoC/peripheral registers.

Add memory management files for metag. Meta's 32bit virtual address space is split into two halves: - local (0x08000000-0x7fffffff): traditionally local to a hardware thread and incoherent between hardware threads. Each hardware thread has it's own local MMU table. On Meta2 the local space can be globally coherent (GCOn) if the cache partitions coincide. - global (0x88000000-0xffff0000): coherent and traditionally global between hardware threads. On Meta2, each hardware thread has it's own global MMU table. The low 128MiB of each half is non-MMUable and maps directly to the physical address space: - 0x00010000-0x07ffffff: contains Meta core registers and maps SoC bus - 0x80000000-0x87ffffff: contains low latency global core memories Linux usually further splits the local virtual address space like this: - 0x08000000-0x3fffffff: user mappings - 0x40000000-0x7fffffff: kernel mappings Signed-off-by: NJames Hogan <james.hogan@imgtec.com>

Add cache and TLB handling code for metag, including the required callbacks used by MM switches and DMA operations. Caches can be partitioned between the hardware threads and the global space, however this is usually configured by the bootloader so Linux doesn't make any changes to this configuration. TLBs aren't configurable, so only need consideration to flush them. On Meta1 the L1 cache was VIVT which required a full flush on MM switch. Meta2 has a VIPT L1 cache so it doesn't require the full flush on MM switch. Meta2 can also have a writeback L2 with hardware prefetch which requires some special handling. Support is optional, and the L2 can be detected and initialised by Linux. Signed-off-by: NJames Hogan <james.hogan@imgtec.com>

Add boot code for metag. Due to the multi-threaded nature of Meta it is not uncommon for an RTOS or bare metal application to be started on other hardware threads by the bootloader. Since there is a single MMU switch which affects all threads, the MMU is traditionally configured by the bootloader prior to starting Linux. The bootloader passes a structure to Linux which among other things contains information about memory regions which have been mapped. Linux then assumes control of the local heap memory region. A kernel arguments string pointer or a flattened device tree pointer can be provided in the third argument. Signed-off-by: NJames Hogan <james.hogan@imgtec.com>

Some 32 bit architectures require 64 bit values to be aligned (for example Meta which has 64 bit read/write instructions). These require 8 byte alignment of event data too, so use !CONFIG_HAVE_64BIT_ALIGNED_ACCESS instead of !CONFIG_64BIT || CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to decide alignment, and align buffer_data_page::data accordingly.

On 64 bit architectures with no efficient unaligned access, padding and explicit alignment must be added in various places to prevent unaligned 64bit accesses (such as taskstats and trace ring buffer). However this also needs to apply to 32 bit architectures with 64 bit accesses requiring alignment such as metag. This is solved by adding a new Kconfig symbol HAVE_64BIT_ALIGNED_ACCESS which defaults to 64BIT && !HAVE_EFFICIENT_UNALIGNED_ACCESS, and can be explicitly selected by METAG and any other relevant architectures. This can be used in various places to determine whether 64bit alignment is required.

Commit c060f943 ("mm: use aligned zone start for pfn_to_bitidx calculation") fixed out calculation of the index into the pageblock bitmap when a !SPARSEMEM zome was not aligned to pageblock_nr_pages. However, the _allocation_ of that bitmap had never taken this alignment requirement into accout, so depending on the exact size and alignment of the zone, the use of that index could then access past the allocation, resulting in some very subtle memory corruption. This was reported (and bisected) by Ingo Molnar: one of his random config builds would hang with certain very specific kernel command line options. In the meantime, commit c060f943 has been marked for stable, so this fix needs to be back-ported to the stable kernels that backported the commit to use the right alignment.

As reported by Klaus Schmidinger: "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a device (using stb0899). After this call I check 'errno' for EOPNOTSUPP to determine whether this device supports this call. This used to work just fine, until a few months ago I noticed that my devices using stb0899 didn't display their signal quality in VDR's OSD any more. After further investigation I found that ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but rather ENOTTY. And since I stop getting the signal quality in case any unknown errno value appears, this broke my signal quality query function." While the changes reflect what is there at: http://comments.gmane.org/gmane.linux.kernel/1235728 it does cause regression on userspace. So, revert it to stop the damage.

" Jan took a look at the preliminary patch and came up a fix that solves this problem: "This code gets called after all registers other than those handled by IRET got already restored, hence a null selector in %ds or a non-null one that got loaded from a code or read-only data descriptor would cause a kernel mode fault (with the potential of crashing the kernel as a whole, if panic_on_oops is set)." The way to fix this is to realize that the we can only relay on the registers that IRET restores. The two that are guaranteed are the %cs and %ss as they are always fixed GDT selectors. Also they are inaccessible from user mode - so they cannot be altered. This is the approach taken in this patch. Another alternative option suggested by Jan would be to relay on the subtle realization that using the %ebp or %esp relative references uses the %ss segment. In which case we could switch from using %eax to %ebp and would not need the %ss over-rides. That would also require one extra instruction to compensate for the one place where the register is used as scaled index. However Andrew pointed out that is too subtle and if further work was to be done in this code-path it could escape folks attention and lead to accidents.
