#     copy_xstate_to_kernel: Fix typo which caused GDB regression
#     
#     This fixes a regression encountered while running the
#     gdb.base/corefile.exp test in GDB's test suite.
#     
#     In my testing, the typo prevented the sw_reserved field of struct
#     fxregs_state from being output to the kernel XSAVES area.  Thus the
#     correct mask corresponding to XCR0 was not present in the core file for
#     GDB to interrogate, resulting in the following behavior:
#     
#        [kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
#        Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...
#        [New LWP 232880]
#     
#        warning: Unexpected size of section `.reg-xstate/232880' in core file.
#     
#     With the typo fixed, the test works again as expected.
