Mikulas Patocka 409c1b250e parisc: fix bugs in pa_memcpy ... The patch 554bfeceb8 ("parisc: Fix access fault handling in pa_memcpy()") reimplements the pa_memcpy function. Unfortunatelly, it makes the kernel unbootable. The crash happens in the function ide_complete_cmd where memcpy is called with the same source and destination address. This patch fixes a few bugs in pa_memcpy: * When jumping to .Lcopy_loop_16 for the first time, don't skip the instruction "ldi 31,t0" (this bug made the kernel unbootable) * Use the COND macro when comparing length, so that the comparison is 64-bit (a theoretical issue, in case the length is greater than 0xffffffff) * Don't use the COND macro after the "extru" instruction (the PA-RISC specification says that the upper 32-bits of extru result are undefined, although they are set to zero in practice) * Fix exception addresses in .Lcopy16_fault and .Lcopy8_fault * Rename .Lcopy_loop_4 to .Lcopy_loop_8 (so that it is consistent with .Lcopy8_fault) Cc: <stable@vger.kernel.org> # v4.9+ Fixes: 554bfeceb8 ("parisc: Fix access fault handling in pa_memcpy()") Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Helge Deller <deller@gmx.de>		2017-04-15 17:24:05 +02:00
