Miller" Date: Tue, 30 Nov 2010 20:15:58 -0800 Subject: sparc: Write to prom console using indirect buffer. sparc64 systems have a restriction in that passing in buffer addressses above 4GB to prom calls is not reliable. We end up violating this when we do prom console writes, because we use an on-stack buffer to translate '\n' into '\r\n'. So instead, do this translation into an intermediate buffer, which is in the kernel image and thus below 4GB, then pass that to the PROM console write calls. On the 32-bit side we don't have to deal with any of these issues, so the new prom_console_write_buf() uses the existing prom_nbputchar() implementation. However we can now mark those routines static. Since the 64-bit side completely uses new code we can delete the putchar bits as they are now completely unused. Signed-off-by: David S.

During suspend, the console semaphore is acquired by the console suspend method (console_suspend()) so the try_acquire_console_sem() will always fail and suspend will be aborted. To fix, introduce a check so the console semaphore is only attempted during idle, and not during suspend. Also use the same check so that the console semaphore is not prematurely released during resume. Thanks to Paul Walmsley for suggesting adding the same check during resume.

Mon, 13 Dec 2010 14:59:51 +0900 Subject: sh: Enable deprecated IRQ chip APIs for MFD and GPIOLIB drivers. There are still quite a number of MFD and GPIO expander drivers that are using the old irq_chip APIs that haven't had a chance to update during the .37 cycle, resulting in allyes/modconfig errors on some configurations. Mark Brown has done most of the legwork to get these fixed up in .38, so this should just be a .37 stop-gap that we can drop at the end of the .38 merge window.

This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.

However, the ownership is never acquired in the v6_dma_inv_range function when cleaning the first line and flushing the last one, in case the address is not aligned to D_CACHE_LINE_SIZE boundary.
