40 hourskernel/amd64: Introduce flexible IPI managementIan Moffett
This commit greatly improves the handling of how inter-processor interrupts are allocated and managed. Previously Hyra used handlers at fixed interrupt vectors for IPIs, however, that is very rigid and not very scalable at all. With the new IPI framework, one may allocate IPIs by calling 'md_ipi_alloc()' and initializing the handler field. To send an IPI to a specific processor, one can use cpu_ipi_send() and pass the specific CPU structure as well as the IPI identifier. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel: xhci: Ensure portno is valid for portscIan Moffett
In the previous implementation, passing 0 or values higher than 'hc->maxports' would not be filtered and would result in underflow/overflow Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel: xhci: Add xhci_stop_hc() to stop the xHCIan Moffett
Implement a new xhci_stop_hc() an call it before we perform a reset. We cannot be certain that the firmware (e.g., UEFI, BIOS) took the care to stop the xHCI before passing control over to us. Signed-off-by: Ian Moffett <ian@osmora.org>

Do not return an error in xhci_start_hc() if it is already running as it complicates things. Signed-off-by: Ian Moffett <ian@osmora.org>

5 dayskernel: sysctl: Allow 'old*' fields to be NULLIan Moffett
When setting sysctl variables from userspace, the 'old' fields will unused and thus typically be set to NULL. This commit modifies the behaviour of do_sysctl() to enable this. Signed-off-by: Ian Moffett <ian@osmora.org>

Since we are approaching the point to where we'll need to set sysctl variables from userspace. It would be a wise idea to actually set the length of the new data. Signed-off-by: Ian Moffett <ian@osmora.org>
