The nodemgr host thread can exit on its own even when kthread_should_stop is not true, on receiving a signal (might never happen in practice, as it ignores signals). But considering kthread_stop() must not be mixed with kthreads that can exit on their own, I think changing the code like this is clearer. This change means the thread can cut its sleep short when receive a signal but looking at the code around, that sounds okay (and again, it might never actually recieve a signal in practice).

Extremly low values are of dubious usefulness anyway but in this case they actually were killing Qemu which simply wasn't able to complete mips_next_event() within 0x30 100MHz cycles even on fast hosts. Signed-off-by:Ralf Baechle <ralf@linux-mips.org>

Turns out b868868a wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.

improve performance of sys_time(). sys_time() returns time in seconds, but it does so by calling do_gettimeofday() and then returning the tv_sec portion of the GTOD time. But the data structure "xtime", which is updated by every timer/scheduler tick, already offers HZ granularity time. the patch improves the sysbench oltp macrobenchmark by 4-5% on an AMD dual-core system: v2.6.23: #threads 1: transactions: 4073 (407.23 per sec.) 2: transactions: 8530 (852.81 per sec.) 3: transactions: 8321 (831.88 per sec.) 4: transactions: 8407 (840.58 per sec.) 5: transactions: 8070 (806.74 per sec.) v2.6.23 + sys_time-speedup.patch: 1: transactions: 4281 (428.09 per sec.) 2: transactions: 8910 (890.85 per sec.) 3: transactions: 8659 (865.79 per sec.) 4: transactions: 8676 (867.34 per sec.) 5: transactions: 8532 (852.91 per sec.) and by 4-5% on an Intel dual-core system too: 2.6.23: 1: transactions: 4560 (455.94 per sec.) 2: transactions: 10094 (1009.30 per sec.) 3: transactions: 9755 (975.36 per sec.) 4: transactions: 9859 (985.78 per sec.) 5: transactions: 9701 (969.72 per sec.) 2.6.23 + sys_time-speedup.patch: 1: transactions: 4779 (477.84 per sec.) 2: transactions: 10103 (1010.14 per sec.) 3: transactions: 10141 (1013.93 per sec.) 4: transactions: 10371 (1036.89 per sec.) 5: transactions: 10178 (1017.50 per sec.)

There is a test in tgafb_mono_imageblit() for a colour image with a fall-back to cfb_imageblit(). The test is not necessary as the only caller, which is tgafb_imageblit(), checks it too and only invokes this function for monochrome images. It looks like a left-over from before some changes to tgafb_imageblit(). Signed-off-by:

The pixel mask calculation in tgafb_mono_imageblit() uses a variable left-shift on a 32-bit data type by up to 32. Shifting by the width of a data type or more produces an unpredictable result according to the C standard. Rather than widening the data type this fix makes sure the count is between 0 and 31. The reason is not to penalise 32-bit platforms with operation on a "long long" type for a marginal case that is meant not to happen (blitting an image of a zero width). The reason it has escaped for so long is the Alpha, being purely 64-bit, :-) does not mask the shift out to 32 bits. This is a valid implementation -- producing the correct result certainly falls within "unpredictable behaviour". It does trigger on MIPS though and it is the recent merge of the TC support which only enabled the driver for use on anything other than the Alpha. For MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as it should be and the frame buffer is not updated. Signed-off-by:

As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular cursor can still be seen blinking in the upper left part of the screen. It is fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE, KD_TEXT) call done by something in userspace, perhaps by X itself, while the tty is still in graphics mode. And when the tty is in KD_TEXT mode, the cursor timer is restarted. Although this is a userspace problem, we can work around it by delaying the restart of the cursor timer until an fbcon_switch() is called. In other words, the cursor timer will not be restarted even if a KD_TEXT mode switch is requested. Regression potential: Present but low Signed-off-by:
