sh: check return code of request_irq

2021-11-26T10:58:43Z

[ Upstream commit 0e38225c92c7964482a8bb6b3e37fde4319e965c ] request_irq is marked __must_check, but the call in shx3_prepare_cpus has a void return type, so it can't propagate failure to the caller. Follow cues from hexagon and just print an error. Fixes: c7936b9abcf5 ("sh: smp: Hook in to the generic IPI handler for SH-X3 SMP.")

sh: Fix validation of system call number

2020-08-21T08:52:53Z

[ Upstream commit 04a8a3d0a73f51c7c2da84f494db7ec1df230e69 ] The slow path for traced system call entries accessed a wrong memory location to get the number of the maximum allowed system call number. Renumber the numbered "local" label for the correct location to avoid collisions with actual local labels.

commit 940d4113f3306e07a1f86541489b686d1a979d54 upstream. New gcc (4.8 or later) used new shift helper functions. So we need added new helper to private libgcc. Signed-off-by: Yoshinori Sato Signed-off-by: Rich Felker Cc: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

sh: fix debug trap failure to process signals before return to user

2018-05-30T05:49:07Z

[ Upstream commit 96a598996f6ac518ac79839ecbb17c91af91f4f7 ] When responding to a debug trap (breakpoint) in userspace, the kernel's trap handler raised SIGTRAP but returned from the trap via a code path that ignored pending signals, resulting in an infinite loop re-executing the trapping instruction.

[ Upstream commit a752ba18af8285e3eeda572f40dddaebff0c3621 ] Even though most of its registers are 8-bit wide, the IRDA has two 16-bit registers that make it a 16-bit peripheral and not a 8-bit peripheral with addresses shifted by one. Fix the registers offset in the driver and the platform data regshift value.
