linux-postmarketos-exynos4: upgrade to 5.15-rc2 (MR 2546) Also add patches from the Replicant project to fix so that charging works, and patches from the linux-pm list to fix the SOC INTR message that has been spamming our dmesg (issue https://gitlab.com/postmarketOS/pmaports/-/issues/1214).

From 70df2c08b907b391d354d80f136e21251efe5d44 Mon Sep 17 00:00:00 2001
Add package main/linux-postmarketos-exynos4 (MR 1634) The devices supported by this package are Galaxy S3 (GT-I9300, GT-I9305, SHV-E210K/L/S) and the Galaxy Note 2 (GT-N7100, GT-N7105) - a family of boards also known by the codename "Midas" - and the Galaxy S2 (GT-I9100) From this list, only the i9100 doesn't support the bootimg method. Because of this, this kernel package is using the isorec method for all the devices on the list. Additionally, for the midas devices, there is no problem with this because the boot.img file is, in fact, a copy of the kernel+initramfs on the pmos boot partition and what the isorec initramfs does is actually to load the initramfs on that partition directly (at least on my understanding).

Subject: [PATCH 01/10] ARM: decompressor: Flush tlb before swiching domain 0
to client mode
Add package main/linux-postmarketos-exynos4 (MR 1634) The devices supported by this package are Galaxy S3 (GT-I9300, GT-I9305, SHV-E210K/L/S) and the Galaxy Note 2 (GT-N7100, GT-N7105) - a family of boards also known by the codename "Midas" - and the Galaxy S2 (GT-I9100) From this list, only the i9100 doesn't support the bootimg method. Because of this, this kernel package is using the isorec method for all the devices on the list. Additionally, for the midas devices, there is no problem with this because the boot.img file is, in fact, a copy of the kernel+initramfs on the pmos boot partition and what the isorec initramfs does is actually to load the initramfs on that partition directly (at least on my understanding).

If the bootloader used a page table that is incompatible with domain 0
in client mode, and boots with the mmu on, then swithing domain 0 to
client mode causes a fault if we don't flush the tlb after updating
the page table pointer.
v2: Add ISB before loading dacr.
