2012-01-03security: Fix security_old_inode_init_security() when CONFIG_SECURITY is not setJan Kara
Commit 1e39f384bb01 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6cbb1: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by: Jorge Bastos <mysql.jorge@decimal.pt> Acked-by: James Morris <jmorris@namei.org> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-01-03mfd/db8500-prcmu: remove support for early silicon revisionsLinus Walleij
The DB8500 ED (Early Drop) and V1 are only available inside of ST-Ericsson or partners, we have actively replaced and scrapped these prototypes. All Nova products on the open market (such as the Snowball board) are based on V2 and later ASIC variants. So let us focus on supporting the silicon that will be used and delete this to get a clear overview.

2012-01-03net/davinci: do not use all descriptors for tx packetsSascha Hauer
The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>

However, Kconfig uses the broader ARCH_MXS symbol and this way even makes the fec-driver default for MX23. Adapt Kconfig to use the more precise SOC_IMX28 as well.

2012-01-03sch_sfq: dont put new flow at the end of flowsEric Dumazet
SFQ enqueue algo puts a new flow _behind_ all pre-existing flows in the circular list. In fact this is probably an old SFQ implementation bug. 100 Mbits = ~8333 full frames per second, or ~8 frames per ms. With 50 flows, it means your "new flow" will have to wait 50 packets being sent before its own packet. Thats the ~6ms. We certainly can change SFQ to give a priority advantage to new flows, so that next dequeued packet is taken from a new flow, not an old one.

2012-01-03ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch]Kukjin Kim
This patch introduces common.[ch] which are used only in the arch/arm/mach-exynos/ directory. The common.c file merges the cpu.c, init.c, irq-combiner.c and irq-eint.c files which are used commonly on EXYNOS SoCs and the common.h file replaces with plat/exynos4.h file.

2012-01-03Enable 32 bit flash support for iMX21ADS boardJaccon Bastiaansen
The kernel configuration for the i.MX21ADS board (imx_v4_v5_defconfig) doesn't enable 32 bit flash support. But the i.MX21ADS specific code adds a 32 bit flash device, resulting in a kernel that refuses to boot.
