arch/hexagon: fix kernel/dma.c build warning

2018-10-13T07:09:30Z

[ Upstream commit 200f351e27f014fcbf69b544b0b4b72aeaf45fd3 ] Fix build warning in arch/hexagon/kernel/dma.c by casting a void * to unsigned long to match the function parameter type. ../arch/hexagon/kernel/dma.c: In function 'arch_dma_alloc': ../arch/hexagon/kernel/dma.c:51:5: warning: passing argument 2 of 'gen_pool_add' makes integer from pointer without a cast [enabled by default] ../include/linux/genalloc.h:112:19: note: expected 'long unsigned int' but argument is of type 'void *' Signed-off-by: Randy Dunlap Cc: Yoshinori Sato Cc: Rich Felker Cc: linux-sh@vger.kernel.org Patch-mainline: linux-kernel @ 07/20/2018, 20:17 [rkuo@codeaurora.org: fixed architecture name] Signed-off-by: Richard Kuo Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

hexagon: Fix build failures in linux-next

2016-10-10T01:23:56Z

[ Upstream commit cb84c2b401d9cead5508cfed57b59b6d5feffdac ] hexagon:defconfig fails to build in linux-next since commit 332fd7c4fef5 ("genirq: Generic chip: Change irq_reg_{readl,writel} arguments"). The primary build failure is arch/hexagon/include/asm/cacheflush.h: In function 'copy_to_user_page': arch/hexagon/include/asm/cacheflush.h:89:22: error: 'VM_EXEC' undeclared This is the result of including of from , which is now necessary due to the use of readl and writel from irq.h. This causes recursive inclusions in hexagon code; cacheflush.h is included from mm.h prior to the definition of VM_EXEC. Fix the problem by moving copy_to_user_page from the hexagon include file to arch/hexagon/mm/cache.c, similar to other architectures. After this change, several redefinitions of readl and writel are reported. Those are caused by recursive inclusions of io.h and asm/cacheflush.h. Fix those problems by reducing the number of files included from those files. Also, it was necessary to stop including asm-generic/cacheflush.h from asm/cacheflush.h. Instead, functionality originally provided by asm-generic/cacheflush.h is now coded in asm/cacheflush.h directly.

hexagon: Use sigsp()

Use sigsp() instead of the open coded variant. Signed-off-by: Richard Weinberger

hexagon: Use get_signal() signal_setup_done()

2014-08-06T11:02:14Z

Use the more generic functions get_signal() signal_setup_done() for signal delivery. Acked-by: Richard Kuo Signed-off-by: Richard Weinberger

smp, hexagon: kill SMP single function call interrupt

2014-04-04T23:20:01Z

Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one intterupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.

'pm_power_off' is a function pointer, not a function, so need change its type, and also need export it, or can not pass compiling with allmodconfig.
