Although U8500 and U5500 platforms use paltform dma, Inventra dma specific code can work for them for the most part. Only difference is for the Rx path where this patch is making use of request->short_not_ok to select dma mode. usb: musb: ux500: add dma name for ux500 usb: musb: ux500: add dma glue layer for ux500 DMA is mainly intended for mass storage class. Unaligned sizes and buffers are not supported. usb: musb: ux500: add configuration and build options for ux500 dma usb: musb: clear AUTOSET while clearing DMAENAB On the completion of tx dma, dma is disabled by clearing MUSB_TXCSR_DMAENAB in TXCSR. If MUSB_TXCSR_AUTOSET was set in txstate() it will remain set although it is not needed in PIO mode. Clear it as soon as it is not needed. usb: musb: ux500: copy dma mask from platform device to musb device musb code checks dma mask before calling dma hooks. usb: musb: do not release dma channel on channel_program failure Musb hcd releases dma channel (hw_ep->tx_channel / hw_ep->rx_channel ) if ->channel_program() fails. A null hw_ep->tx_channel is then used to continue the transfer in pio mode. Next call to musb_ep_program() will try to allocate the dma channel again. This patch allows the transfer to continue in pio mode if ->channel_program() fails without releasing the dma channel. usb: musb: restore rxcsr on channel_program failure Rxcsr is configured for dma transfer before calling ->channel_program(). Restore rxcsr if ->channel_program() fails. usb: musb: ux500: enable host side dma support Host side dma support for ux500 is enabled by piggybacking on Inventra dma support.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case. This backports the workaround from the x86/trampoline branch, and as Peter says: "This is not a minimal fix, not at all, but it is a tested code base." * 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: When printing an error, say relative or absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug x86, realmode: 16-bit real-mode code support for relocs tool (*) That's a manly release numbering system.

2012-05-19memcg,thp: fix res_counter:96 regressionHugh Dickins
Occasionally, testing memcg's move_charge_at_immigrate on rc7 shows a flurry of hundreds of warnings at kernel/res_counter.c:96, where res_counter_uncharge_locked() does WARN_ON(counter->usage < val). The first trace of each flurry implicates __mem_cgroup_cancel_charge() of mc.precharge, and an audit of mc.precharge handling points to mem_cgroup_move_charge_pte_range()'s THP handling in commit 12724850e806 ("memcg: avoid THP split in task migration"). Checking !mc.precharge is good everywhere else, when a single page is to be charged; but here the "mc.precharge -= HPAGE_PMD_NR" likely to follow, is liable to result in underflow (a lot can change since the precharge was estimated). Simply check against HPAGE_PMD_NR: there's probably a better alternative, trying precharge for more, splitting if unsuccessful; but this one-liner is safer for now - no kernel/res_counter.c:96 warnings seen in 26 hours.

When the relocs tool throws an error, let the error message say if it is an absolute or relative symbol. This should make it a lot more clear what action the programmer needs to take and should help us find the reason if additional symbol bugs show up. Signed-off-by: H.

GNU ld 2.22.52.0.1 has a bug that it blindly changes symbols from section-relative to absolute if they are in a section of zero length. This turns the symbols __init_begin and __init_end into absolute symbols. Let the relocs program know that those should be treated as relative symbols.
