*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary This PR addresses an issue with the `flush_gdt` routine in `arch/x86/src/486/i486_utils.S`. `flush_gdt` previously had an error where `eax` was moved into the stack slot of the first function parameter, instead moving the gdt pointer from the stack into eax: ```asm movl %eax, 4(%esp) lgdt (%eax) ``` This only did not crash because `eax` was not clobbered between where it was pushed to the stack for the call to `gdt_flush` by `up_lowsetup`, and its use in `lgdt`: ```asm 108e58: 50 push %eax 108e59: e8 f9 0f 00 00 call 109e57 <gdt_flush> ``` ## Impact No direct impact, as the buggy code coincidentally still worked. ## Testing - Host: Linux x86_64 -
