| | | | | | | | | | | | | | | | | | | | | | There was clearly supposed to be a break statement here. Currently we use the k2 ata timings instead of sh ata ones we intended. Probably no one has this hardware anymore so it likely doesn't make a difference beyond the static checker warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the HPT366 data sheet, PCI config space dword 0x40-0x43 bits 11:8 specify the primary drive cmd_high_time, however, currently just 3 bits of the 4 are being used because the mask is 0x07 and not 0x0f. Fix the mask, allowing for the 40MHz clock to be detected. Also add in missing space between switch and parenthesis to clean up a checkpatch warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 0000000000000000 l F .text.unlikely 00000000000000e4 cmd640x_init_one And after the change it is as follows: 00000000000000d2 l F .init.text 00000000000000df cmd640x_init_one Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the IDE specific LED trigger to a generic disk activity LED trigger. The libata core is now a trigger source just like before the IDE disk driver. It's merely a replacement of the string ide by disk. The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is widely used by any ibook/powerbook owners with great satisfaction. Likewise, it is very often used successfully on different ARM platforms. Unlike the original patch, the existing 'ide-disk' trigger is still available for backward compatibility. That reduce the amount of patches in affected device trees out of the mainline kernel. For further development, the new name 'disk-activity' should be used.

Lets change the initcall to be the equivalent device_initcall, so that when reading the driver code, there is no doubt it is builtin-only. Unlike other similar changes, we leave the module.h header to be included since this code interacts with other drivers and needs to know what a struct module is. Cc: "David S.

* ide: silence some underflow warningsDan Carpenter2016-01-181-8/+8
| | | | | | | | | | | | | | | | | | | | | | | Back in the day we used to just say this code was root only so it was ok that the bounds checking was sloppy. These days it annoys static checkers so we fix it. In the original code "c > INT_MAX" was never true since "c" was an int. I am not sure what was intended so I left it alone. But because I made "c" unsigned it means we don't have a warning any more. The second warning is that we cap "i" but allow negatives leading to an underflow of the ide_disks_chs[] array. The third set of warnings is because these values come from the user and we cap most of the upper bounds but allow negative values. Negative cylinders doesn't make sense. drivers/ide/ide.c:262 ide_set_disk_chs() warn: impossible condition '(c > ((~0 >> 1))) => (s32min-s32max > s32max)' drivers/ide/ide.c:270 ide_set_disk_chs() warn: check 'ide_disks_chs[i]' for negative offsets 'i' = s32min. extra = 's32min-19' drivers/ide/ide.c:271 ide_set_disk_chs() warn: no lower bound on 'h' Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

* mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIMMel Gorman2015-11-0610-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | __GFP_WAIT was used to signal that the caller was in atomic context and could not sleep. Now it is possible to distinguish between true atomic context and callers that are not willing to sleep. The latter should clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing __GFP_WAIT behaves differently, there is a risk that people will clear the wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly indicate what it does -- setting it allows all reclaim activity, clearing them prevents it.

These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

So it's questionable whether they should contribute to the random pool in the first place. - Calling add_disk_randomness() has a lot of overhead. There are more reliable sources for randomness than non-rotational block devices.
