2015-06-03crypto: aesni - Convert top-level rfc4106 algorithm to new interfaceHerbert Xu
This patch converts rfc4106-gcm-aesni to the new AEAD interface. The low-level interface remains as is for now because we can't touch it until cryptd itself is upgraded. In the conversion I've also removed the duplicate copy of the context in the top-level algorithm. Now all processing is carried out in the low-level __driver-gcm-aes-aesni algorithm.

2015-06-02powerpc: mpc85xx: flush the l1 cache before cpu down in kexecKevin Hao
We observe a "Zero PT_NOTE entries found" warning when vmcore_init() is running on the dump-capture kernel. Actually the PT_NOTE segments is not empty, but the entries generated by crash_save_cpu() are not flushed to the memory before we reset these cores. So we should flush the l1 cache as what we do in cpu hotplug. With this change, we can also kill the mpc85xx_smp_flush_dcache_kexec() since that becomes unnecessary. Please note: this only fix the issue on e500 core, we still need to implement the function to flush the l2 cache for the e500mc core. Fortunately we already had proposing patch for this support [1]. Hope we can fix this issue for e500mc after that merged.

2015-06-02powerpc/8xx: Implementation of PAGE_EXECLEROY Christophe
This patch implements PAGE_EXEC capability on the 8xx. All pages PP exec bits are set to 000, which means Execute for Supervisor and no Execute for User. Then we use the APG to say whether accesses are according to Page rules, "all Supervisor" rules (Exec for all) and "all User" rules (Exec for noone) Therefore, we define 4 APG groups. msb is _PAGE_EXEC, lsb is _PAGE_USER. MI_AP is initialised as follows: GP0 (00) => Not User, no exec => 11 (all accesses performed as user) GP1 (01) => User but no exec => 11 (all accesses performed as user) GP2 (10) => Not User, exec => 01 (rights according to page definition) GP3 (11) => User, exec => 00 (all accesses performed as supervisor) Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> [scottwood: comments: s/exec/data/ on data side, and s/pages/pages'/] Signed-off-by: Scott Wood <scottwood@freescale.com>
2015-06-02powerpc/8xx: Handle PAGE_USER via APG bitsLEROY Christophe
Use of APG for handling PAGE_USER. All pages PP exec bits are set to either 000 or 011, which means respectively RW for Supervisor and no access for User, or RO for Supervisor and no access for user. Then we use the APG to say whether accesses are according to Page rules or "all Supervisor" rules (Access to all) Therefore, we define 2 APG groups corresponding to _PAGE_USER. Mx_AP are initialised as follows: GP0 => No user => 01 (all accesses performed according to page definition) GP1 => User => 00 (all accesses performed as supervisor according to page definition) This removes the special 8xx handling in pte_update() Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>

2015-06-02powerpc/8xx: Add support for TASK_SIZE greater than 0x80000000LEROY Christophe
By default, TASK_SIZE is set to 0x80000000 for PPC_8xx, which is most likely sufficient for most cases. However, kernel configuration allows to set TASK_SIZE to another value, so the 8xx shall handle it. This patch also takes into account the case of PAGE_OFFSET lower than 0x80000000, allthought most of the time it is equal to 0xC0000000 Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>
2015-06-02powerpc/8xx: Use SPRG2 instead of DAR for saving r3LEROY Christophe

2015-06-02powerpc/8xx: dont save CR in SCRATCH registersLEROY Christophe
CR only needs to be preserved when checking if we are handling a kernel address. So we can preserve CR in a register: - In ITLBMiss, check is done only when CONFIG_MODULES is defined. Otherwise we don't need to do anything at all with CR. - We use r10, then we reload SRR0/MD_EPN into r10 when CR is restored Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>

2015-06-03ARM: dts: Add Odroid XU3 Lite supportKrzysztof Kozlowski
The Odroid XU3 Lite is almost the same as XU3, except: 1. Lower CPU frequencies (1.8 GHz for A15 and 1.3 GHz for A7, instead of 2.0 GHz and 1.4 GHz). 2. No DisplayPort. 3. No TI INA231 energy measurement sensors. This patch moves common nodes (which is almost everything) to a common DTSI file and adds a new XU3 Lite DTS.
