2010-12-20omap: rx51: Switch rx51_tpa6130a2_data __initdata to__initdata_or_moduleJarkko Nikula
If the TPA6130 is compiled as module the id and power_gpio values are arbitrary at module probing time since the rx51_tpa6130a2_data was marked as __initdata. Fix this by using __initdata_or_module. Then __initdata is defined only if the kernel is built without CONFIG_MODULES and omitted otherwise. Signed-off-by: Jarkko Nikula <jhnikula@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-12-20omap: pandora: fix wifi supportGrazvydas Ignotas
After commit ed919b0 "mmc: sdio: fix runtime PM anomalies by introducing MMC_CAP_POWER_OFF_CARD" it is required to specify MMC_CAP_POWER_OFF_CARD to have runtime PM support. As the wl1251 driver expects card to be powered down when it's not used, wifi will no longer work after interface is brought down at least once without functioning runtime PM. Fix this by declaring MMC_CAP_POWER_OFF_CARD for MMC3. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-12-20Fix IGEPv2 second MMC channel power supplyMarc Zyngier
Commit 72f381ba056 (omap3: Remove VMMC2 regulator on IGEP v2) removed an unused regulator entry, but left the second MMC channel (used by the Libertas WLAN module) without link to power regulator. This causes the SDIO module to fail being detected. This patch adds the two regulators that actually feed the WLAN module (1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the second channel is properly detected. Details of the power supply implementation were kindly provided by Enric Balletbo i Serra. Also change vmmc1 to use symbolic names instead of direct device reference. Tested on an IGEPv2 Rev-B.

2010-12-18omap4: l2x0: Enable early BRESP bitSantosh Shilimkar
The AXI protocol specifies that the write response can only be sent back to an AXI master when the last write data has been accepted. This optimization enables the PL310 to send the write response of certain write transactions as soon as the store buffer accepts the write address. This behavior is not compatible with the AXI protocol and is disabled by default. You enable this optimization by setting the Early BRESP Enable bit in the Auxiliary Control Register (bit [30]).

2010-12-18omap4: l2x0: Set share override bitSantosh Shilimkar
Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Tested-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-12-18omap4: l2x0: enable instruction and data prefetchingMans Rullgard
Enabling L2 prefetching improves performance as shown on Panda ES2.1 board with mem test, and it has measurable impact on performances. I think we should consider it, even though it damages "writes" a bit. (rebased to k.org) Usually the prefetch is used at both levels together L1 + L2, however, to enable the CP15 prefetch engines, these are under security, and on GP devices, we cannot enable it(e.g. on PandaBoard). However, just enabling PL310 prefetch seems to provide performance improvement, as shown in the data below (from Ubuntu) and would be a great thing to pull in. What prefetch does is enable automatic next line prefetching. With this enabled, whenever the PL310 receives a cachable read request, it automatically prefetches the following cache line as well.

Commit f2ce62312650 (OMAP: WDT: Split OMAP1 and OMAP2PLUS device registration) removed omap_init_wdt and related structures from plat-omap/devices.c.

2010-12-15install_special_mapping skips security_file_mmap check.Tavis Ormandy
The install_special_mapping routine (used, for example, to setup the vdso) skips the security check before insert_vm_struct, allowing a local attacker to bypass the mmap_min_addr security restriction by limiting the available pages for special mappings. bprm_mm_init() also skips the check, and although I don't think this can be used to bypass any restrictions, I don't see any reason not to have the security check. $ uname -m x86_64 $ cat /proc/sys/vm/mmap_min_addr 65536 $ cat install_special_mapping.s section .bss resb BSS_SIZE section .text global _start _start: mov eax, __NR_pause int 0x80 $ nasm -D__NR_pause=29 -DBSS_SIZE=0xfffed000 -f elf -o install_special_mapping.o install_special_mapping.s $ ld -m elf_i386 -Ttext=0x10000 -Tbss=0x11000 -o install_special_mapping install_special_mapping.o $ ./install_special_mapping & [1] 14303 $ cat /proc/14303/maps 0000f000-00010000 r-xp 00000000 00:00 0 [vdso] 00010000-00011000 r-xp 00001000 00:19 2453665 /home/taviso/install_special_mapping 00011000-ffffe000 rwxp 00000000 00:00 0 [stack] It's worth noting that Red Hat are shipping with mmap_min_addr set to 4096.
