2010-06-09r8169: fix mdio_read and update mdio_write according to hw specsTimo Teräs1-3/+9
Realtek confirmed that a 20us delay is needed after mdio_read and mdio_write operations. Reduce the delay in mdio_write, and add it to mdio_read too. Also add a comment that the 20us is from hw specs. Signed-off-by: Timo Teräs <[email protected]> Acked-by: Francois Romieu <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2010-06-09gianfar: Revive the driver for eTSEC devices (disable timestamping)Anton Vorontsov1-2/+1
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

2010-06-09FRV: Reinstate null behaviour for the GDB remote protocol 'p' commandDavid Howells1-0/+6
Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0dafd ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error.

2010-06-08writeback: limit write_cache_pages integrity scanning to current EOFDave Chinner1-0/+15
sync can currently take a really long time if a concurrent writer is extending a file. The problem is that the dirty pages on the address space grow in the same direction as write_cache_pages scans, so if the writer keeps ahead of writeback, the writeback will not terminate until the writer stops adding dirty pages. For a data integrity sync, we only need to write the pages dirty at the time we start the writeback, so we can stop scanning once we get to the page that was at the end of the file at the time the scan started. This will prevent operations like copying a large file preventing sync from completing as it will not write back pages that were dirtied after the sync was started. This does not impact the existing integrity guarantees, as any dirty page (old or new) within the EOF range at the start of the scan will still be captured. This patch will not prevent sync from blocking on large writes into holes. That requires more complex intervention while this patch only addresses the common append-case of this sync holdoff.

2010-06-08writeback: pay attention to wbc->nr_to_write in write_cache_pagesDave Chinner3-23/+6
If a filesystem writes more than one page in ->writepage, write_cache_pages fails to notice this and continues to attempt writeback when wbc->nr_to_write has gone negative - this trace was captured from XFS: wbc_writeback_start: towrt=1024 wbc_writepage: towrt=1024 wbc_writepage: towrt=0 wbc_writepage: towrt=-1 wbc_writepage: towrt=-5 wbc_writepage: towrt=-21 wbc_writepage: towrt=-85 This has adverse effects on filesystem writeback behaviour. write_cache_pages() needs to terminate after a certain number of pages are written, not after a certain number of calls to ->writepage are made. This is a regression introduced by 17bc6c30cf6bfffd816bdc53682dd46fc34a2cf4 ("vfs: Add no_nrwrite_index_update writeback control flag"), but cannot be reverted directly due to subsequent bug fixes that have gone in on top of it.

When CONFIG_DEBUG_HIGHMEM is used, the fixmap entry used for a highmem page by kmap_atomic() is always cleared by kunmap_atomic(). This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.

Frederic reported that frequency driven swevents didn't work properly and even caused a division-by-zero error. It turns out there are two bugs, the division-by-zero comes from a failure to deal with that in perf_calculate_period(). The other was more interesting and turned out to be a wrong comparison in perf_adjust_period(). The comparison was between an s64 and u64 and got implicitly converted to an unsigned comparison. The problem is that period_left is typically < 0, so it ended up being always true. Cure this by making the local period variables s64.
