2009-04-27sh: Fix up unsigned syscall_nr in SH-5 pt_regs.Paul Mundt

2009-04-04sh: Fix up DSP context save/restore.Michael Trimarchi
There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

2009-03-17sh: Flush only the needed range when unmapping a VMA.Paul Mundt
This follows the ARM change from Aaro Koskinen: When unmapping N pages (e.g. shared memory) the amount of TLB flushes done can be (N*PAGE_SIZE/ZAP_BLOCK_SIZE)*N although it should be N at maximum. With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a noticeable performance penalty when unmapping a large VMA and the system is spending its time in flush_tlb_range(). The problem is that tlb_end_vma() is always flushing the full VMA range. The subrange that needs to be flushed can be calculated by tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins, and is also used by other arches. The speed increase is roughly 3x for 8M mappings and for larger mappings even more. Bits and peices are taken from the ARM patch as well as the existing arch/um implementation that is quite similar. The end result is a significant reduction in both partial and full TLB flushes initiated through flush_tlb_range(). At the same time, the nommu implementation was broken, had a superfluous cache flush, and subsequently would have triggered a BUG_ON() if a code-path had triggered it. Tidy this up for correctness and provide a nopped-out implementation there. More background on the initial discussion can be found at: http://marc.info/?t=123609820900002&r=1&w=2 http://marc.info/?t=123660375800003&r=1&w=2 Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-03-17sh: Support for extended ASIDs on PTEAEX-capable SH-X3 cores.Paul Mundt
This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores that implement the PTAEX register and respective functionality. Presently only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs). The main change is in how the PTE is written out when loading the entry in to the TLB, as well as in how the TLB entry is selectively flushed. While SH-X2 extended mode splits out the memory-mapped U and I-TLB data arrays for extra bits, extended ASID mode splits out the address arrays. While we don't use the memory-mapped data array access, the address array accesses are necessary for selective TLB flushes, so these are implemented newly and replace the generic SH-4 implementation. With this, TLB flushes in switch_mm() are almost non-existent on newer parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-02-15net: new user space API for time stamping of incoming and outgoing packetsPatrick Ohly
User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

2009-01-08NOMMU: Make VMAs per MM as for MMU-mode linuxDavid Howells
Make VMAs per mm_struct as for MMU-mode linux. This solves two problems: (1) In SYSV SHM where nattch for a segment does not reflect the number of shmat's (and forks) done. (2) In mmap() where the VMA's vm_mm is set to point to the parent mm by an exec'ing process when VM_EXECUTABLE is specified, regardless of the fact that a VMA might be shared and already have its vm_mm assigned to another process or a dead process. A new struct (vm_region) is introduced to track a mapped region and to remember the circumstances under which it may be shared and the vm_list_struct structure is discarded as it's no longer required. This patch makes the following additional changes: (1) Regions are now allocated with alloc_pages() rather than kmalloc() and with no recourse to __GFP_COMP, so the pages are not composite. Instead, each page has a reference on it held by the region. Anything else that is interested in such a page will have to get a reference on it to retain it. When the pages are released due to unmapping, each page is passed to put_page() and will be freed when the page usage count reaches zero. (2) Excess pages are trimmed after an allocation as the allocation must be made as a power-of-2 quantity of pages. (3) VMAs are added to the parent MM's R/B tree and mmap lists. As an MM may end up with overlapping VMAs within the tree, the VMA struct address is appended to the sort key. (4) Non-anonymous VMAs are now added to the backing inode's prio list. (5) Holes may be punched in anonymous VMAs with munmap(), releasing parts of the backing region. The VMA and region structs will be split if necessary. (6) sys_shmdt() only releases one attachment to a SYSV IPC shared memory segment instead of all the attachments at that addresss. Multiple shmat()'s return the same address under NOMMU-mode instead of different virtual addresses as under MMU-mode. (7) Core dumping for ELF-FDPIC requires fewer exceptions for NOMMU-mode. (8) /proc/maps is now the global list of mapped regions, and may list bits that aren't actually mapped anywhere. (9) /proc/meminfo gains a line (tagged "MmapCopy") that indicates the amount of RAM currently allocated by mmap to hold mappable regions that can't be mapped directly. These are copies of the backing device or file if not anonymous. These changes make NOMMU mode more similar to MMU mode. The downside is that NOMMU mode requires some extra memory to track things over NOMMU without this patch (VMAs are no longer shared, and there are now region structs).
