-Now as we jumped on the `startup_32` from the [arch/x86/boot/compressed/head_64.S](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/compressed/head_64.S) we will not find anything related to the interrupt handling here. The `startup_32` contains code that makes preparations before the transition into [long mode](http://en.wikipedia.org/wiki/Long_mode) and directly jumps in to it. The `long mode` entry is located in `startup_64` and it makes preparations before the [kernel decompression](https://0xax.gitbooks.io/linux-insides/content/Booting/linux-bootstrap-5.html) that occurs in the `decompress_kernel` from the [arch/x86/boot/compressed/misc.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/compressed/misc.c). After the kernel is decompressed, we jump on the `startup_64` from the [arch/x86/kernel/head_64.S](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/kernel/head_64.S). In the `startup_64` we start to build identity-mapped pages. After we have built identity-mapped pages, checked the [NX](http://en.wikipedia.org/wiki/NX_bit) bit, setup the `Extended Feature Enable Register` (see in links), and updated the early `Global Descriptor Table` with the `lgdt` instruction, we need to setup `gs` register with the following code:

In `startup_64` we start to build identity-mapped pages, check the [NX](http://en.wikipedia.org/wiki/NX_bit) bit, setup the `Extended Feature Enable Register` (see in links) and update the early `Global Descriptor Table` with the `lgdt` instruction.
