Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats (bpp = 12, 16, and 24) respectively. When double-buffering both Y planes appear before the C planes (Y-Y-C-C), as opposed to Y-C-Y-C. Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use .bpp to distiguish between the 3 modes. The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and should be set accordingly. .nonstd must be set to 0 for RGB mode. Due to the encoding of YUV data, the framebuffer will clear to green instead of black. In YUV 420 mode, panning is only possible in 2 line increments. Additionally in YUV 420 mode the vertical resolution of the framebuffer must be an even number.

This patch splits the pll configs up on pll versions. This allows easy adding of other known good pll values. Additionally it made it possible to remove invalid configurations resulting in better behaviour for such cases. The resulting clocks are no longer stored resulting in some computing overhead on each mode change. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

The clocks can be easily recalculated by the timing and refresh value. This brings us one step closer to removing VIAs modetable and use generic ones and being easier extensible. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

Before this patch only clocks that perfectly match were used and if none existed this was not handled properly. This patch changes this to always use the closest clock supported. This should behave like before for clocks that have a perfect match but be much saner for clocks which are slightly off. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

This patch removes the direct lookup table for resolution+refresh and pixclock by calculating this information from the mode table. Removes a lot of dupllication and error potential by just doing a little more calculations on each mode change. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

Since a8f80e8f any process with CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't allow anybody load any module not related to networking. This patch restricts an ability of autoloading modules to netdev modules with explicit aliases. This fixes CVE-2011-1019. Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior of loading netdev modules by name (without any prefix) for processes with CAP_SYS_MODULE to maintain the compatibility with network scripts that use autoloading netdev modules by aliases like "eth0", "wlan0". Currently there are only three users of the feature in the upstream kernel: ipip, ip_gre and sit. root@albatros:~# capsh --drop=$(seq -s, 0 11),$(seq -s, 13 34) -- root@albatros:~# grep Cap /proc/$$/status CapInh: 0000000000000000 CapPrm: fffffff800001000 CapEff: fffffff800001000 CapBnd: fffffff800001000 root@albatros:~# modprobe xfs FATAL: Error inserting xfs (/lib/modules/2.6.38-rc6-00001-g2bf4ca3/kernel/fs/xfs/xfs.ko): Operation not permitted root@albatros:~# lsmod | grep xfs root@albatros:~# ifconfig xfs xfs: error fetching interface information: Device not found root@albatros:~# lsmod | grep xfs root@albatros:~# lsmod | grep sit root@albatros:~# ifconfig sit sit: error fetching interface information: Device not found root@albatros:~# lsmod | grep sit root@albatros:~# ifconfig sit0 sit0 Link encap:IPv6-in-IPv4 NOARP MTU:1480 Metric:1 root@albatros:~# lsmod | grep sit sit 10457 0 tunnel4 2957 1 sit For CAP_SYS_MODULE module loading is still relaxed: root@albatros:~# grep Cap /proc/$$/status CapInh: 0000000000000000 CapPrm: ffffffffffffffff CapEff: ffffffffffffffff CapBnd: ffffffffffffffff root@albatros:~# ifconfig xfs xfs: error fetching interface information: Device not found root@albatros:~# lsmod | grep xfs xfs 745319 0 Reference: https://lkml.org/lkml/2011/2/24/203Signed-off-by: Vasiliy Kulikov <segoon@openwall.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Acked-by: David S.

The combination of commit 8154c5d2 and 93c22703 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This patch removes all internal uses of another mostly artificial value. It does duplicate the information of the maximum resolution and it is not flexible as only a few resolutions exist.

Return 0 on failure. This will cause the initialization of the driver to fail and prevent the driver from loading if the BIOS cannot handle the PCC interface command to "get frequency". Otherwise, the driver will load and display a very high value like "4294967274" (which is actually -EINVAL) for frequency: # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 4294967274 Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> CC: stable@kernel.org Signed-off-by: Dave Jones <davej@redhat.com>

30201e7f ("mmc: skip detection of nonremovable cards on rescan") allowed skipping detection of nonremovable cards on mmc_rescan(). The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

a) struct inode is not going to be freed under ->d_compare(); however, the thing PROC_I(inode)->sysctl points to just might. Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it! Said that, I really suspect that this check can be simply killed. Nick? Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
