From: NeilBrown <neilb@cse.unsw.edu.au> From: Josh Litherland <josh@emperorlinux.com> The XOR routine selection process is often confusing as it often doesn't choose the routine that measures the fastest, as sometime one routine is known to have better cache performance. This patch avoids the comparison when there is a known best choice, and makes the report more meaningful. Signed-off-by:

From: NeilBrown <neilb@cse.unsw.edu.au> There is severe bit-rot in this code, which is to say that it doesn't work at all: an io error during read will do bad things. It should work better with this patch. Signed-off-by:

From: William Lee Irwin III <wli@holomorphy.com> During stress testing at Oracle to determine the maximum number of clients 2.6 can service, it was discovered that the failure mode of excessive numbers of clients was kernel deadlock. The following patch removes the check if (nr_swap_pages > 0) from out_of_memory() as this heuristic fails to detect memory exhaustion due to pinned allocations, directly causing the aforementioned deadlock.

From: "Chen, Kenneth W" <kenneth.w.chen@intel.com> Turn on CONFIG_HIGHMEM and CONFIG_HUGETLBFS. Try to config the hugetlb pool: [root@quokka]# echo 100 > /proc/sys/vm/nr_hugepages [root@quokka]# grep HugePage /proc/meminfo HugePages_Total: 100 HugePages_Free: 100 [root@quokka]# echo 20 > /proc/sys/vm/nr_hugepages [root@quokka]# grep HugePage /proc/meminfo HugePages_Total: 0 HugePages_Free: 0 [root@quokka]# echo 100 > /proc/sys/vm/nr_hugepages [root@quokka]# grep HugePage /proc/meminfo HugePages_Total: 100 HugePages_Free: 100 [root@quokka]# echo 0 > /proc/sys/vm/nr_hugepages [root@quokka]# grep HugePage /proc/meminfo HugePages_Total: 31 HugePages_Free: 31 The argument "count" passed to try_to_free_low() is the config parameter for desired hugetlb page pool size. But the implementation took that input argument as number of pages to free. It also decrement the config parameter as well. All give random behavior depend on how many hugetlb pages are in normal/highmem zone. A two line fix in try_to_free_low() would be: - if (!--count) - return 0; + if (count >= nr_huge_pages) + return count; But more appropriately, that function shouldn't return anything. Signed-off-by:

From: Andy Whitcroft <apw@shadowen.org> Being able to recover the configuration from a kernel is very useful and it would be nice to default this option to Yes. Currently, to have the config available both from the image (using extract-ikconfig) and via /proc we keep two copies of the original .config in the kernel. One in plain text and one gzip compressed. This is not optimal. This patch removes the plain text version of the configuration and updates the extraction tools to locate and use the gzip'd version of the file. This has the added bonus of providing us with the exact same results in both cases, the original .config; including the comments. Signed-off-by:

From: David Eger <eger@havoc.gtf.org> This patch brings the cirrusfb driver up to date with 2.6. cirrusfb has suffered bit rot like you wouldn't believe (last updated... 2.3.x era?). The driver will now compile again, and you can change to a high resolution text mode with stty. Known defects: doesn't play nice with X, nor fbset. C = Cosmetic change L = Logical change A = API change W = register Writing change (1-CA) fb_info and cirrusfb_info: - mostly cosmetic, but a lot less confusing, and no more nasty casting. It used to be stylish to embed struct fb_info_gen (now struct fb_info) as the first member of struct clgenfb_info (now struct cirrusfb_info), and then you'd cast to the deisred struct. Now we pass the size of our data structure to framebuffer_alloc(), and we make fb_info and cirrusfb_info reference each other with pointers (as in radeonfb). In the old code, there two declarations were common: clgenfb_info *fb_info; clgenfb_info *info; since there's also a 'struct fb_info' now, I found this really confusing, and unified usage as: cirrusfb_info *cinfo; fb_info *info; This accounts for a lot of the search and replace cosmetic upgrade. (2-A) All of the FB knowledge of FB internals is gone in 2.6 (3-LW) revised maxclock numbers (cirrusfb_board_info_rec.maxclock[5]) In my quest to get fbset to work, I borrowed some maxclock data from the X.Org tree for various chipsets. It didn't really seem to help. oh well. (3-LA) upgraded PCI registration Instead of doing PCI walking from the driver, we hand off a pci_device_id table to the PCI subsystem and just get called when it finds a relevant board. (4-L) striking lots of __init and __initdata specifiers I was running into some things not working when I moved the call to init_vgachip() from the driver registration to set_par(). I thought perhaps this was due to some things being marked __init accidentally so I axed said annotations. Turns out it was something else. See 5. (5-LA) delayed chip initialization, nasty double-set_par() pseudo-bug Tony says that the fb drivers shouldn't do any chipset initialization until they get a set_par() call. This way, fb modules can be safely unloaded if no one gets around to using them, and the vga_con -> fbcon hand off is smoother, as fbcon can still grab the back-scroll data from vga_con... In any case, moving the calls to init_vgachip() and fbgen_do_set_var() from driver initialization to set_par() revealed that the cirrus register-writing function needs to be called twice for a mode change to work. I don't understand why. (6-LA) split clgen_decode_var() into the bits that check the var and the bits that actually generate register information (par/regs) to write Adding modedb hooks here might actually fix fbset, i think... (7-LW) No longer write the palette in init_vgachip() nor in set_par(). Someone else (fbcon?) seems to be making its own calls to setcolreg() for us. (8-LW) setcolreg() -- while removing all of the console cruft, I had to try to reconstitute the palette code. I think I got this right, but I could be off -- the penguin boots in the correct colors at least ;-) (9-L) pan_display() - we don't do wrap, silly. that's only on the amiga. (10-L) pan+BLT - to make pan play nicely with copyarea()/fillrect() I had to add a couple of calls to cirrusfb_WaitBLT() to make sure the engine is idle. (11-LW) cirrusfb_blank() - I upgraded the switch here to use the new VESA_* blanking mode constants. I think I translated the right logic for the right blanking levels. Signed-off-by:

From: "Martin J.
