The remainder of the const qualifiers on cpumask ops. My cpumask overhaul missed specifying the const qualifiers in cpumask.h. Subsequently, Linus has added some. The following should provide the remainder of them. It also fixes one src vs dst variable misnaming. Using crosstool on 2.6.7-mm5, I have built the following arch's with the following change included: alpha ia64 powerpc-405 powerpc-750 sparc sparc64 x86_64 Signed-off-by:

Found by the new Stanford locking checker. Minimal fix for a deadlock in sysvfs: get_branch() can take read_lock(&pointers_lock), but one caller already has a write_lock. Perhaps some of the "oh we raced, drop everything and try again" logic in there can go away now, but this is enugh to fix the obvious deadlock. Signed-off-by:

I did some simple benchmarking (time cat linux-2.6.7-mm5/MAINTAINERS) between 2.4 and 2.6 and I am not satisfied with what I see (It's claimed that fbdev-2.6 is faster than 2.4). The reason for the claim: 2.4 putcs - draw small amounts of data a lot of times 2.6 putcs - draw larger amounts of data a fewer times The way characters are drawn in 2.6 is optimal for accelerated drivers but should also give a speed boost for drivers that rely on software drawing. However the penaly incurred when preparing a large bitmap from a number of small bitmaps is currently very high. This is because of the following reasons: 1 fb_move_buf_{aligned|unaligned} uses pixmap->{out|in}buf. This is very expensive since outbuf and inbuf methods process only a byte or 2 of data at a time. 2 fb_sys_outbuf (the default method for pixmap->outbuf) uses memcpy(). Not a good choice if moving only a few bytes. 3 fb_move_buf_unaligned (used for fonts such as 12x22) also involves a lot of bit operations + a lot of calls to outbuf/inbuf which proportionately increases the penaly. So, I thought of separating fb_move_buf_* to fb_iomove_buf_* and fb_sysmove_buf_*. fb_iomove_buf_* - used if drivers specified outbuf and inbuf methods fb_sysmove_buf_* - used if drivers have no outbuf or inbuf methods *Most, if not all drivers fall in the second category.

The speed gain is constant but significant. Below is a patch against 2.6.7-mm5. The effects will be very noticeable with drivers that uses SCROLL_REDRAW, but one should still see some speed gain even if SCROLL_YPAN/YWRAP is used. Separated fb_sys_move_* into fb_iosys_move_* and fb_sysmove_* to reduce penalty when constructing fb_image->data from character maps. In my testcase (1024x768 SCROLL_REDRAW), I get a ~1.7 second advantage with 'time cat MAINTAINERS' using 8x16 fonts and ~5.7 seconds with 12x22 fonts. The speed gain is independent of acceleration or color depth. Signed-off-by:Antonino Daplas <adaplas@pol.net> Signed-off-by:

Two years ago, OGAWA Hirofumi removed some ugly code and added a few simple tests to the FAT filesystem code, intended to avoid recognizing non-FAT as FAT (for people who fail to specify rootfstype=, forcing the kernel to guess). That worked fairly well, until this year. I have now seen a thread in Czech and a report from Holland that involved the "FAT: bogus sectors-per-track value" error message. The patch below removes this test again. The advantage is that some real-life FAT filesystems can be mounted again. The disadvantage that more non-FAT fss will be accepted as FAT. Ferry van Steen <freaky@bananateam.nl> reports "the patch Andries Brouwer gave me seems to work". Signed-off-by:
